Save Mother Earth

I have always felt why do we need a day to celebrate or shower our love to our near and dear ones ,for they are always special and the love must not be bottled up for a single day.

But, having a World Environment Day is very essential and completely justified. 

Why is it significant?

For a simple reason that we cannot sustain without Mother Earth and her benediction. 

Now that the cause is defined, how do we do it?

Well, though this can be a collective effort, I personally feel it is the responsibility of each individual to save our environment in every possible way.In the long run, these can give pave way for the collective tackling of this issue to a larger extent. Where do we start it? I would say the realization must start from the schools. The effective of the outcome can be multiple times. And this comes from a personal experience too.

"Save Mother Earth" - was a drama performed by me during my school days to promote saving our environment from being plundered by us. And this did have a profound effect on me. From then on, I have always made it a point not to waste our resources, save energy and resource whenever possible.

When children are made to understand the importance of saving our environment, they would definitely adhere to many ways of preventing the degradation. And it doesn't stop there. They would even spread it to their families and talk sense to them.And the awareness will grow.exponentially. 

Every school must make it a practice to preach children the seriousness of the environmental concerns. And it shouldn't stop there. They must be made to practice what is being taught. You may ask how?A simple practice of switching off the fans and lights when they are done for the day  would inculcate the habit of saving electricity. Measures like Rewards/Appreciations for the most eco-friendly class can do wonders.I feel schools should definitely do this to ignite the awareness beacon among the students.

The realization is the initial step in this gargantuan task. The next step is ardently following the measures/practice (conscious effort needed though).This has to be followed rigorously , no matter what the situation is.The next step is to talk sense to people doing unacceptable practices. Though the reactions can be from a simple acceptance to exchange of heated words, we must make it a point to let them know what they are doing is not acceptable( with the use of good language and gestures).

Let us all pledge to save our environment in every possible way and strive to make it a better place to live in!!!

Back to where we started...the college!!

My friend had sent me the pictures of my college during her recent visit. And these snaps triggered me some of the best memories of my life which I would cherish for my lifetime. I guess you wouldn't agree for more :)

College is a paradoxical noun. We hate when we attend them and we miss once we are out of it.And I ain't an exception.

A college is a place where we evolve as a person.Its a place where threads of life long friendships are woven , a place where you discover yourself, a place to realize our dreams and a place where some of the life's important lessons are taught.Those are the formative years in a person's life that prepares her/him to face the world. I bet all of you would agree with me.

Apart from academic, assignments, marks they were important things taught in our colleges , many a times not by our professors. These lessons are always remembered.All of us have memories attached to our college and those stay etched for eternity. Every insignificant event/thing - birthday celebrations, numerous outings , silly  misunderstandings , late night chatting , "Good morning" messages, last minute exam preparations, internal marks( Biggest villan !!) , crushes , mock teasing, seminars,FYPs (final year projects) et all  becomes the most important part of our memories which we would always try to relive.

Life changes tremendously after college. We are caught up in the frenzy race of work, higher studies et all and we find it tough to re-live the college life. Lofty pay packets or higher positions or a series of post graduate degrees fail to bring back those satisfying and gratifying moments experienced by us in our colleges.

PS: I would like to thank all my friends for making my college stay the most memorable experience of all times.

State of Mind!!

Most of us (that includes me as well) have been caught in a variety of quagmire situations – melting pot of a mixture of problems and we find ourselves completely burned out.  All we hear is a loud thumping blast of the below lines of the song.

“Confusion hi confusion hai solution kuch patha nahi

 Solution jo mila to saala question kya tha pata nahi”

The meaning of the song goes like this –

 We see confusion everywhere and solution is nowhere to be seen. And by the time a solution is found, there is no clue about the question!!)

We find ourselves incapable of deciding on the course of action, let alone follow them. In scientific terms, it is a psychotic congregation of incompetent cognition (Well this is to emphasize the importance of how a complex state we find ourselves in).

We expend all our energies to figure out a solution (Lets not discuss how effective it is!!) and reach a point where we fail to notice the light at the end of the tunnel and our motivation levels hit an all time low. What do we do then?

From my observations, I have seen a majority of us keep thinking to find a solution. The harder we try, the more it eludes us. But many of us fail to understand this and thus, we are caught in the mirage of impediment for ages (Yeah a little exaggeration!!). So what do we do then?

A quote by Dalai Lama helps us to have some perspective on what can be done.

“We can never obtain peace in the outer world until we make peace with ourselves.”

How do we do it is the million dollar question?

So the first action point is to pause thinking about the anxieties and give them a good rest. In simple words, we must forget it for the time being. When I find myself at such junctures, instant detachment helps. The next thing is to concentrate on activities/things that make us  happy and brings back the mental equilibrium. It is essential to rightly identify those activities. It could be anything from staring blankly at nothing , eating meditating ( you name anything under the sun..). But the essential part is, never think about the problem or the solution during this time frame. This doesn't come in a day. All we need to do is practice and I m sure it will help us in the long run.

But how long do we do this? Ahhh...that's something I leave it to you for figuring out. It is a trial and error process and I don't have a definitive period for that as it usually varies for each of us.

Some of the activities in which I would like to indulge myself are watching movies, going for long walks, talking to my close friends, sleeping , playing badminton , writing an article etc. This calms down the mind and brings back the thinking capacity. 

And this followed by a steaming cup of tea brings me back to my right state and mind :)

Health Tip !!

Staying fit is an arduous task...(since the weight control curriculum that we always miss to follow!!)


Here's a simple fitness tip I came across to stay in shape sans the rigid exercise regime. The additional perk is it also helps to improve the skin tones.


All we need to do is drink half a liter water , one hour before break fast , lunch and dinner. 


Well give it a try and let me know if it works!!

My New Found Interest!

I have always prefered to stay behind the lens in most of the ocassions and in the recent times my curiosity with the camera has magnified by 10X times. Photography has stimulated my creativity grey cells.


So I just thought of sharing some of the pictures I clicked and know your comments - maybe a picture or two in a week.


Here comes the first one:

A bird's eye view from my room's window on a rainy day!

PS : Comments are most welcome!

Athisaya Ragam

I had heard the song " Athisaya Ragam"  from the movie Aboorva Rangangal after a  long time and these lines immediately caught my attention:

"Oru puram paarthaal mithilayin maithili

marupuram paarthaal kaviri maadhavi  

Mugam mattum paartthal nilavin edhiroli  

Muzhuvadhum parthal avaloru bairavi"

I was amazed at how Mr. Kannadasan had deftly described the female protagonist in these 4 lines. He has effectively portrayed Bhairavi's character in these 4 lines. I was bewildered by his use of words - eloquent and complementing. 

The shortest " About me" I have even come across :) 

He is indeed a man of powerful words. Rightly called as " Kaviarasu ( King of Poets)". He is one of the greatest poets of all times 

Here's the song:

. 

Secular India - are we??

The recent SIT's report providing a clean chit to Mr Modi has not been well received. The 2002 Godhra riots where innocent lives were lost, has been a clear black mark in the political career of the highly eulogized image of the man who shaped Gujarat. I have admired and appreciated his efforts to make Gujarat as one of the most promising states in India.Was he unable to check the raging riots of 2002?????

The recent report has cleared him of conspiring or instigating the riots. But then an astute policy maker like Mr. Modi was haplessly incompetent in handling such a heated issue is an irony. The Godhra riots could have been curbed saving many lives, if not for his muteness...Holding the most important post; his inaction is as good as conspiring.

What could be the root cause of such an erratic insurgence that has surfaced very often?

The Hindu - Muslim strained relationships are dated back to the First war of Indian Independence (1857 Sepoy Mutiny), where divide and rule policy was instrumented by the Brits to rule us. Since then, the ruling class has exploited us. From then on, the damage has been irreparable. The final blow to the rift was the 1947 India - Pakistan partition, the largest human migration in world's history. The exploitation by our own politicians has been profound and I see BJP as no exception (and neither Congress...)

Godhra massacre is one such event. We have been plagued by numerous communal riots since our independence. It pains to see that this very issue hasn’t been addressed by our Government for the last 65 years. Hindu –Muslim rivalry isn’t the only form of communal aberrations, but it has remained the longest one and forms the crux of the other such communal tensions. Were there any real measures taken to abridge this gap after Gandhiji's martyrdom? As I see it, no sorts of elucidation have been promoted. This makes me to think if there really existed/exists a way to alleviate this bitterness? Well, if South Africa could reconcile from the dreadful apartheid, can we not? Mr. Mandela played a pivotal role and it was not an easy task. I really wish we had a leader who could have got into the root of this issue and pacified the prevailing communal hatred. I m sure it is a gargantuan task, but not an impossible one.

 On the contrary I find our Constitution further deepening this rift by the policy of reservation. Please don’t get me wrong here. I m not opposing the concept of reservation, the implementation of it is what I would like to question. Undue advantage and exploitation are being done by the political parties based on the caste reservations. They are being used as the cash bank by the parties to win elections or save their deposits. Further, granting reservations even for Post Graduate degree, promotions etc. are highly undesirable traits that add up to the existing woes. This also impedes the growth and development of the country. If India really intends to create a secular state, it has to abolish the reservations in an incremental fashion.

Only two members from a family of the castes/classes entitled for reservation must be eligible for the quota. If the allocation has been used up, no other member form the family is eligible for further reservations. The importance of the opportunity will only then be felt when it is made scare and people will understand its value. Indeed a quota scheme for the quota system (with a lot of tuning). In this set up, eventually the quota system will disappear(not in our times though).

I m sure this proposal would be vehemently opposed by the politicians and no politician would dare to take such a radical step (given that their vote banks would suffer horrendously). This would be a major step to bridge the widening gap between the estranged castes and would help in the creation of a truly secular state in the long run.

Story Writing...

This is my first attempt in writing a short story! Yes.. I had written this for a contest conducted by Reader's Digest.

Silence speaks!

Love is a paradox – easy to feel tough to express. This exact thought was running on Vinod’s mind at the moment. Winding back 3 years of his life, he vividly remembers the first time he had met Harini at his friend’s place. The conversation had kicked off instantly and they becoming friends was inevitable. Despite hailing from different backgrounds – he was a simple lad from a small town near Trichy while she was a metropolitan girl from Chennai, chords of comradeship was gradually entwining them. The sole purpose of Vinod’s stay in Chennai was to fulfill his ambition of becoming a Chartered Account, although his only financial support was his father.

As days rolled by, he liked her openness, genuineness and boldness while she adored his focus on life, never say never attitude. The love was profound and this was acknowledged in silence between them. The soaring relationship was rattled by souring news of his father’s sudden demise. He was surrounded by nimiety of emotions – confused, perplexed, depressed and clueless. He was prepared to call off his studies and go back. But it was Harini who made him realize his gaffe and offered to be with him through the thick and thin by contributing a part of her income to his studies. He took up a part time job and toiled hard to accomplish his dream. All these 3 years, they never expressed their love.

Today, Vinod a financial consultant with a MNC has finally confessed his love for her and a harbinger of happiness awaits them!!

PS: Results aren't out yet and doesn't matter either :) 

Bali - Certainly an Experienceee!!!

A jaunt out of the mundane schedule of a software engineer always finds  its stance high on cards and this trip wasn't an exception !!! We sisters had planned  a trip to propose a toast for our parent's successful completion of 27 fruitful years in amalgamation. Excitement knew no bounds and the destination was BALI!!!!

No history..No geography..!! This is a repertoire on my personal experiences at the Island of Gods.

Lake Batur

I had done my surfing of the net to grasp in as much as I can about Bali. Thanks to wikitravel, for aggrandizing my imaginations about  landscape and picturesque of Bali, the most famous destinations in South-East Asia.

Hopping out of the JetStar airbus, we were greeted by a spurt of sea breeze , gently playing to the tunes of the mighty Indian ocean on one hand and on the other , the vociferous babbles from co-visitors across the globe. A stamp in my passport was all needed to set my foot on this mass of land.

Wading through the roads of Bali I found it to be urbanely rustic , spicing up its painted backdrop. Bali is a complete composite package consisting of jagged coastal lines , lush green rice fields ( Fields on small hills - that's right Terrace Farming) , voluptuous volcanoes and towering mountain ranges.

Mt Batur - Active Volcano

Believe me you can spot a temple at every corner of the street as you would in Chennai. They are the most ubiquitous architecture in Bali owing to the presence of dominant Hindu culture from as early as 100 BC. Unlike the Indonesian archipelago, where Islam is the dominant religion, Bali remains a devout Hindu state. Every day is greeted with offerings in house, workplace, hotels , streets etc.These offerings consist of a small leaf tray containing flowers, rice , incandescent sticks. Religion  is fused with every aspect of life in Bali. There are mass processions, similar to those seen in the Indian culture , happening every alternative day.

The main deity is carried around on a palanquin accompanied by a band playing music. Men get to do this while the women dressed in their traditional attire carry the offerings required for performing the prayers.Every body in the temple perform the ritual in unison.Balinese Hinduism is derived from the traditional Hindu values. 

They worship Brahma ( The Creator) , Vishnu (The Preserver) and Shiva (The destroyer) represented by Red , White and Black colors respectively.I just forgot to elaborate on the traditional attire - it is called Sarong and Kain. And even the foreigners have to follow this custom when entering the temples. Yeah .. you got it right.. we did wear those attires!!And we were lucky to witness such a procession at Pura Kehan Temple ,the second largest temple  and be a part of it.

Celebrations have always been a part of Balinese culture. They celebrate death with as much fervor as they welcome  birth. This is a cemetery at Monkey forest, a reserve for more than 350 primates  ( Well... in simple words --monkeys ). 

Pura Kehen Temple

Now talking about monkeys, I have had close life threatening encounters ( an extra dose of exaggeration ) which made my dear family members go in splits in the Uluwatu Temple( Temple on the coral reef). One tried to pounce on me while another tried to snatch my bag. Well I did make a ruckus which was quite a fun to witness.(Found it from laughing faces around...!!!)

Leaving aside the surprise onset from monkeys, the sunset at the temple was a spectacular sight to witness. The furiously thrashing waves against the reef visually enamored the scene. 

Uluwatu Temple

Trips are bound to be full of experiences and so was this. I have always been fond of waters and beaches lure me. But word's fail me. Myself and my sister were eager to try our hands in " Scuba Diving". The idea seemed pretty cool when we started off. So off we went in a ferry to embark on an expedition ( that's a little fill of fabrication.. too much of Bollywood's influence i must admit ...;)!!). The trainer was giving  out instructions on the sign language and using the buoyancy control device. During all of this, my mom was very anxious and was cautioning me 

( Not my sister who had snorkeling experience to her credits!!) which was of-course futile. Then came the moment ... I was asked to take a plunge into the otherwise calm Indian ocean.

 I did but only after a little hesitation and was asked to fit the breathing apparatus. Here I fumbled to breathe through my mouth when inside the water and was gasping for air. That moment I knew what suffocation was!!! My trainer asked me to try it out once again , but I still couldn't manage to breathe through my mouth.. After my repeated failure, I gave up!! Fear gripped me and I didn't want to do it anymore...( my fondness for water didn't diminish by a speck..). My mom was most relieved when I went on-board and my dad was happily mimicking my gestures in water ( I must admit it was funny to look at .. ). Hmmm,.. my sister went on to complete her mission successfully and even brought a star fish as a token of her voyage. We took a snap and let the sea star back to her domicile. I vowed to come back sometime soon and accomplish this unfinished task of mine :) and I will..

Terrace farms

The Barong is the almost synonymous to Bali ( Not in literal sense though!!) Anybody visiting Bali will definitely know what Barong is.. It is a mythical creature representing the good spirit. The Barong dance is the most famous of all dances.And as a remembrance , we had Barong drawn on our T-shirt - the Bathik art , which is very famous. Hot wax is used for this purpose. Silver smiths are also very famous here.These 2 art forms widely flourish in Bali.

Barong Dance

Bali thrives on its agriculture and tourism.Majority of the population is involved in the cultivation. The staple food of Bali is rice and you can see rice fields grown on slopes of hills. Terrace farming is much prevalent here. Apart from rice, Bali chilies are very famous for their hot and spicy characteristics.People in Bali are strictly include meat(any kind..) in their diet. We being purely vegetarians found it a little tough to get food that had no meat. Our driver told us that they eat a diet like ours only when they are sick ( Huh!! couldn't complain though..).

Life style is very simple is Bali , people use 2 wheeler (scooters) as their main means of transport.There is no public means of transport.Their is always an air of tranquility surrounded in their way of living. Fast paced and night life is unknown to this part of Indonesia except for the  commercialized tourist spots and it was indeed refreshing.People retire for the day by sunset and wake up by sunrise. A laid back life devoid of computers , hi-tech gadgets etc. etc. I must say that Bali is still immune to the virus of ultra - modernization.

The Barong Batik

Truly Bali is one of the best holiday destinations to relish and the  enjoyment knew no bounds!!!!!

History repeats itself!!!

When I was glancing through today’s newspaper, the article that caught my immediate attention was Mr.Manmohan’s vow for a stronger Lokpal. I guess this is the nth time I m hearing Government’s co-operation in this. This govt has been advocating corruption and scams of various forms for time immemorial. The recent ones being 2G spectrum, Commonwealth games , Black money stashing at Swiss Banks , Adarsh et all and dates back to Bofors arms deal ( mystery still prevails ), antique biz , Fodder scam and the list continues.Sigh!!!!

Indian Politics has been plagued with ever spreading corruption deterring its growth in the most effective way which none of us can imagine. We are known for our forbearance and we continue to tolerate the humbugs governing us from the National capital. This government is widely perceived as the most corrupt in the history of independent India. And this opaque, corrupt, and driven by greed government was startled on April 5, 2011 by a 72 year old utopian Anna Hazare and the whole country was behind him supporting his crusade against the corruption. People from all walks of life staged protests for implementing the Jan Lokpal Bill and the aftermath was the setting up of a Lokpal drafting committee with govt. representatives who never had an iota of confidence on the effectiveness of Lokpal. I personally feel this committee never took Anna and his request seriously and made a mockery out of him and the bill instead of reaching consensus with Team Anna.

And the climax was reached on 16th Aug, 2011 when Anna and team was arrested before going on a hunger strike for a more stronger anti-corruption bill in New Delhi. The government showed its tyrannical and despotic facet. Is India the largest democratic nation in the world?? Aren’t we denied of our fundamental right to dissent and protest peacefully? The consequence of this arrest has put Congress on its thinking heels. It is time for the government to understand that it is the people’s rage and discontentment that has geared so much attention to this campaign against corruption failing which it has to pay a dear price!!

Isn’t history repeating itself after 64 years????

First Dancing Lesson!!!

 I put on my dancing shoes today in the last 15 yrs !!!Phewww... that's a long timeeeee indeed and I m feeling elated...It involved a great deal of effort from me to gear up and face this challenge... And I must thank my roomy Prat for pulling me into this... Without her this would not have been possible. Thanks Prat!!!! :) :)

Initially, I was apprehensive about my dancing skills and never gave it a try. But trust me it was an exhilarating experience. Though our dancing talent needs to be fine tuned, we were thrilled to shake our legs to some of the latest Bollywood peppy numbers like Sheila ki jawani , Munni Badnam hui, Rang de basanti etc. We just kicked up our heels out at the dancing studio.


We were out of sync, out of breath and missed our beats. But all that mattered the most was we danced after 3 months of planning it out.I m glad we made it for dancing was the top most contender in my inhibitions list.

So what's next??? Well we have decided to join the classes :)


PS: No worries....Classified  Performance... Only for 511 housemates.. :)

Back After a Hiatus!!!

After a long hitch... here I m blogging once again... Been almost 2 years ... Hmmm quite a long time since I visited my blog . So here I am solemnly promising myself to pour down my thoughts more often than my previous track records :)

Honestly I was caught up in the mirage of the so called Masters, exams, submissions, work, pressure et all. And it took me some time to comprehend that illusions go down with its creator. Changes play a pivotal part in this cycle of snaring and liberating us from the clutches of these delusions.

Changes bring us an assorted package  of exulting gladness and jolting despondencies in the most unexpected way -the best way to know ourselves. All one has to do is try to follow what your heart says for it is the ultimate beacon of light. I have loathed changes from the bottom of my heart as it plagues me with anxiety and insecurity. But now I feel they are our teachers who help us to rediscover ourselves when we tend to drown in a quagmire of illusions.

Let’s play it on!! :)

VOID self (temporarily out of reach)!!!!!!!!!!!!!!!!!

At times I go through a plethora of emotions and I m not sure why am I so perplexed????????? I totally lose interest in whatever I do and I guess each one of us at some point of time, pass through this phase of emptiness. Well I call this “VOID phase”. Life is wily at times and we find it monotonous and flat. At this point we feel stagnant and sluggish, a state where anguish soars and level of confidence sours. Maybe this is why we go through this phase. I am trying to figure out the reason solely based on my experience. This phase of “nothingness” (as I call it) turns me into a completely new person I am unaware of for a brief period of time. I am not referring to the usual mood swings that we go through due to various emotional factors.

In this intermittent state, I remain aloof, barely talking to people. May be because I don’t want them to know I could be so emotional or may be a bit of pride in admitting I m distressed. I become arid and all liveliness drains out of me. Even the smallest discomfort can make me shed tears (though not very often).An all time low confidence courts me and I am in constant search for reassurances from anywhere and anybody. I just turn into a zombie (not generalizing… this is about me...)

Off late I have started doing a bit of research to prevent falling into this momentous unapproachable status. One thing I have found that trying out new things or pursuing what we like the most can definitely push us on and on. Actually I feel better when I have vented my thoughts through this write up. So I just figured out a way to avert the “out of reach” state. So it’s just that out of bloom we find our fixes. And this effort has to come from us (self realization!!!).

I haven’t done with the research part and it will keep continuing. Next time I will definitely come up with a lot more ways to stop drooling back to the VOID state.

AN INTRODUCTION TO BUSINESS INTELLIGENCE

DEFINITON:

•Business intelligence (BI) is defined as a set of concepts and procedures that aid in making business decisions based on the facts.

BI is:

•Collecting and refining information from different sources.

•Analyzing and presenting information in useful ways.

WHY BI?

•Provides easy access to information.

•Consistent view of information.

•Helps in making both long term and short term goals.

•Maintains an adaptive and resilient source of information.

•Provides control access to the data.

DATA WAREHOUSING

•Data warehousing is a means to retrieve and analyze data, to extract, transform and load data.

•BI is accomplished using data warehouses.

DATA WAREHOUSE

•A collection of data from multiple sources

ØWithin the organization

ØOutside the organization

•Includes summary, historical as well as operational data.

•Cleansing of data is required.

TYPES OF DATA WAREHOUSES

•Top-down

ØCentralized.

•Bottom-up

ØDistributed.

ARCHITECTURE OF DATA WAREHOUSE

The components of the architecture are

ØSource systems.

ØData staging area.

ØPresentation server.

ØEnd user data access.

SOURCE SYSTEMS

•A system that captures the transactions of the business.

•Also known as legacy systems.

•Maintains little historical data.

•A stovepipe.

DATA STAGING AREA

•A set of processes that clean, transform, combine, de-duplicate, household, archive and prepare source data for

use in the data warehouse.

•Involves activities of sorting and sequential processing.

BASIC PROCESSES OF DATA STAGING

•Extracting.

•Transforming.

•Loading and indexing.

•Quality Assurance Checking.

•Release/Publishing.

•Updating

•Querying.

•Data Feedback/feeding in Reverse.

•Auditing.

•Securing.

•Backing up and Recovering.

PRESENTATION SERVER

•The target machine on which the data warehouse data is organized and stored for querying purpose.

•Data is presented and stored in a dimensional framework.

•This consists of

ØData marts

ØData warehouse

ØOperational data store

DATA MARTS

•Logical subset of the data warehouse.

•This consist of data restricted to a a single process or a group of related business processes.

•Represented using a dimension model.

•They must be built from conformed dimensions and conformed facts.

DATA WAREHOUSE

•Query able source of data.

•Facilitate reporting and analysis of information.

•Union of all data marts.

OPERATIONAL DATA STORE(ODS)

•This is designed to contain low level atomic data with limited history that is captured in real time or near real time

on a less frequent basis.

•The contents of ODS are updated frequently.

•It is designed to perform simple queries on small amount of data.

•4 types of ODS:

ØClass I

ØClass II

ØClass III

ØClass IV

•The original ODS systems were developed as a reporting tool for administrative purposes. They were usually

updated daily and provided reports about business transactions for that day, such as sales totals or orders filled.

This type of system is now referred to as a Class III ODS.

• With changes in technology and business needs, the Class II ODS evolved to track more complex information

such as product and location codes, and to update the database more frequently (perhaps hourly) to reflect

changes.

•Class I ODS systems arose from the development of customer relationship management (CRM). In Class I

systems, synchronous or near-synchronous updates are used to provide customers with consistently valid and

organized information.

•The Class IV ODS, was recently developed with an added capacity for more interaction between the data

warehouse or data mart and the ODS.

END USER DATA ACCESS:

•Users query, analyze and present information stored in data warehouses to support a business need.

PS : The above concepts discussed as merely based on my understanding. Any misstated information is the result of same.
