If Training is tough in real life its easy

In India if you want to go in Engineering you need to qualify Entrance Exam.
in late 90’s Seat available in my state were just 1200 out which I perceived upper class had only about around 400 rest were reserved. out of 1,50,000 Exam participant 400 would be chosen in state Exam. In IIT 2500 seats for around 2,00,000 contestant. But due to more seats and private engineering college senario is changed. infact 2nd year I was getting into second best private Engg college JSS Noida. Then I had just 1 year to finish graduation and dropped because next year I could write CAT, MCA entrance and Bank PO entrance.
I felt fixing minimum percentage to Exam should be crime. Because people circumstances keep Changing Every year should be given chance to compete.
Having said that I was never against reservation I have seen life of few dalits in villages struggling contrary I always used to go everywhere to help and many of my good friends were from same classification. I never believed in this classification as Arya samaj also never believed in Caste-ism.
Now Many people in Europe Take word Arya in different ways it had total different meaning in India. So Drop you pre-conceived notions.
Arya samaj offshoot of Hinduism never believed in Idol worship and Casteism , levelling of people into classes. Everyone was Equal and there is strong focus on non-violence and vegetarianism(but its people choice to think a eat what they like).
And Especially in our area there was very less differentiations. Today’s india has changed everyone to almost of same type I have seen before in hometown Everyone is treated Equal.
The Logic of Life for me was:
“When I was Born Hindu may be in next life I may be Christian or May be Muslim or May be Buddhist.” Can you or I predict it? Ans: NO.
So another version of this logic was may be 150 yrs back in previous life may be i was dalit facing discrimination and today as perceived upper class face another differentiations.
So people who took benefit in name of upper caste may be in rebirth taking benefit in name of dalit class now.
I always felt like in Europe if everyone is treated Equally and fairly by law instead of going back and thinking What was 200 yrs back it good for any society. Like many EU countries fought war among themselves just 70 yrs back now all together Is it not wonderful?
RE-cycled Soul:
So I never used to differentiate between people. If there is no re-birth how is there is continuity of life? What I mean if people die how new people come with new soul if soul is not recycled. This Re-cycling is big industry in God’s world. By God I mean some force which is controlling the Universe. Which best lengthy definition of God which i read in Rig-veda says “No one can predict What is God?”.
I begin Training for IIT Entrance Exam post 12th class. I actually went first in couching in 11th but When during demo single problem in mathematics went from geometry Asymptotes to differentiation and then Complex integration which required trigonometric substitutions to resolve then use a Algebraic equation. So I could see its 2 class syllabus in 1 problem. So I though it would be wise to cover the syllabus first and then come in coaching But it was mistake because it was just demo. In demo usually to impress student most difficult problem was chosen.
Having lost 2 yrs coaching post 12th teacher Told me one thing: :” If training is hard then Exam is Easy”.
So I We begin learning really challenging mathematics, IE irdov problem in physics, Morrison Boyd (organic Chemistry), JD Lee (inorganic chemistry). And a new Book HC verma (physical Chemistry).
I really used to Wonder How can  I.E. Irdov write such a master piece that its timeless? its relevance never Stops the accumulation of difficulty and range cannot be replicated.
There were problems which required lot of out of box thinking. Actually if you cannot think out of box you cannot solve them. in short people say Tricky question.
But yet There was structure if you follow structure you can reach there provided you identified trick involved.
After some times I had to drop physics and Chemistry due to financial stress but I continued taking mathematics for almost 3 years. The Structure was such that if you cannot go through coaching it was not impossible but it was tough.
And if there was some problem back home which does not let you focus on study it was double whamy for Student life joint family issues in India there is always conflict between parties involved leading to stress and there is this feeling of comparisons drawn.
But My parents did everything to insulate those things from our life yet something were not under there control.
The Schedule
So I had B.Sc classes as well this coaching. Our college was tough attendance was necessary so I had to attend college as well coaching. One Time I went to a professor and asked him
Sir I had coaching conflicting with lab sessions Can I skip? He told me : “Not possible Why are you here?”. No change of time was also allowed.
It was always rush hour for me on cycle to move fast 4 hours college 8 kms cycle then coaching 4 hours. Then problems solving at home. We would get around 200 problems every week in mathematics alone. tight schedule meant I could give max 5-6 hours Each day but there were not 3 but 5 subjects then B.Sc 9 subjects. total 14 subjects but I would usually leave B.Sc subjects.
I asked father Should I drop BSc can concentrate only on This :”He told me senario There was a Girl among office friend Who tried medical Entrance 3 yrs but then had come back to study BSc only. So you have to do both”. No waste of time.
I would usually drop off hours second shift B Sc lab and classes.
The Drop saviour:
One time a professor in Bsc pointed to me that I have rarely seen you in class why?
I went silent then he said meet me after class. I had to skip classes for coaching Entrance Exam.So he was teaching integration for B.Sc and not for Entrance which was second priority for me. At End of class he asked any one has any problem.
I was struck in one problem in coaching practise Sheet. it was integration of e to power suppose 1/3 multiplied by (1 +t)^m. I told me that. it required trigonometric substitution to reduce to easy alegebra then application of L.I.A.T.E rule.(First log then inverse trigonometry, algebra then trigonometry, then Exponential functions.

He took out book started applying ramanujan provided solutions steps.
He said : First failed, second rule failed, third rule failed and end of 6 th rule it was 2 hours Extra time consumed but problem was not solved. He told I will look this later and there was one mathematician who gave lot of things in integrations ramanujan had he lived longer then we would have many problems solved. He died in age of 32.
After Class over I went to professor because he asked me to meet after class and told him before he tells anything Sir “I have another mathematics problem”. he said to me come later we will discuss.
I was saved from absent ism due to coaching hours. Next time student use to tell me that professor is avoiding the pathway to skip questions. So i was saved permanently.
But he was very helpful to many students. But I had curious different case altogether.

Coke Vs Pepsi of :Datawarehousing ETL Vs ELT

The Coke and Pepsi are always fighting to have bigger pie in international drinks market.
Both are present in 180+ countries agressively pursuing the pie of market share.

The Datwarehouses are different animals on block. They are databases But they are not normalized. They do not follow all 12 Codd Rules. But yet source and Target are RDBMS.
The Structure Where its saved Whether in Star Schema or Snow-flake is denormalized as possible like flat file structures. More Constraints slows down the join process.

So there are less restrained much Faster file based alternatives for databases which Emerged for need to store unstructured data and achieve 5V massive volume, variety, velocity etc.. Read below links:
Which are have also found favour in ETL world with Hadoop. Now Every ETL allows hadoop connector or adapter to Extract data from hadoop HDFS so service in HDFS and similar.

ETL process

ETL Extract-Transform-Load
ETL where transformation happens in staging area.
Extract data from sources , put in staging area cleanse it, transform data and Then Load in Target Datawarehouse. So popular Tools like informatica, datastage or ab-initio use this approach. Like in Informatica for fetching data or Extract Phase we can use fast source-qualifier transformation OR use Joiner transformation when we have multiple different databases like both SQL Server and Oracle although may be slow but can take both input but Source qualifier may require single vendor but is fast.
After Extracting We can use Filter transformation to filter out unwanted rows in staging area. Then load into target Databases.

ELT Extract Load and then Transform.
Extract data from disparate sources , Load the data into RDBMS engine first after . Then use RDBMS facility to Cleanse and Transform Data. This Approach was popularised By Oracle because Oracle Already had Database Intellectual property and was motivated to increase its usage.So Why does cleansing and Transformation outside the RDBMS into staging area rather within RDBMS engine. Oracle ODI Oracle Data integrator uses this concept of ELT not ETL bit reversal from routine.

So like Pepsi Vs Cola wave of Advertisement and gorilla marketing or To showcase Each other products strengths and hide weakness Games continue here Also in ETL world of data warehousing. Each one has its own merits and demerits.

Check:Example Decision Making based on Famous Sayings/quotations my be wrong

For Everything Which Exist in World There is a saying for it or proverb for it.
But For any proverb there is Anti-proverb So Life’s important or unimportant decisions should not be based on Proverb but based on real-time decisions you face.
There is a saying “If you are right you should not worry anything.”
So fear/worry does not mean Actual fear/worry but it means possibility of not succeeding in idealistic way. In today’s world there is less scope for idealism due to conflict of interest but person has to take middle path and take all people along. You cannot make everyone happy there would be always a set of people unhappy and ready to drag you down.

Anti-proverb / opposite saying:
Saying “Straight Trees are cut first”.
Another way to understand this is :So if you are straight forward in your approach and may be not diplomatic about it may be you are first one to face wrath.
In the world of competition mediocrity is not a choice or 0ption. But there is conflict in market there exist space for Every category or segment of product now How do you decide which approach? Both are right based on circumstances or situations ?
Let me give one Example from Stock Market:
Boom period : In time of boom invest more on equity and take risk to garner more return.
Recessionary Times: In case of Bust period invest more in debt funds and take less risk because risky stock can give negative returns.
Uncertainty: In case of uncertainty you need to balance your portfolio other word Diverse your risk to multiple options Or in other words Follow Middle-path.
So There Exists Market for Everything as long as you able to make rational decisions.
The irr-rational behaviour may exists due ill-informed decisions, or lack of environmental knowledge or due to lack of knowledge itself or Unknown Unknown. Lack of environmental knowledge like sitting in Earth you cannot visualize what might be situation in Space?
You need to go through cycle of gravity and weightlessness.

Decision making:
Decisions should be based on hard facts or situations faced. The Abstract thinking of proverb cannot be considered an alternative unless its validated by situational parameters. Based on These parameter ranking which is nearest one should be chosen heuristically or on opposite based on measured metrics based rules/score. The nearness of the score justify decision or Risk taken based on situation involved.

Something Which is right for one person cannot be right for another person. Yet Sometimes Copycat does work? Some decisions perfected over period of wisdom can be taken as rule but yet there always a space where they can be improved or contrary view.
There nothing in world which is impossible Other world of saying is There is no rule which is ultimate there is always scope to Explore and find meanings.

Having said That Let me tell you a story.
One fine day There are 7 people happen to pass through a jungle. It was getting Night so the 7 people (1 old women, One young Businessmen, One trader, one soldier, one teacher , a doctor and a small child ) were passing by A large tree.
Suddenly it started raining and lighting started falling. After many lighting Strikes passed away. People started gossiping with each other. Suddenly there came a topic What is happening Today? Why is this lighting coming when we have no shelter Elsewhere?
Rumours Started spreading Fast among group That there is some person due to which lighting is falling on all of us. Solider telling its due to corrupt businessmen. Businessmen telling it due to corrupt bureaucracy where soldier was employed. Teacher telling its due to doctor who ill-treated patients. And doctor telling its due ill-equipped teacher harming students with half knowledge. Women telling its due to child who may be full of sin.
Then everyone started fighting and blaming each other.
Settlement Rule
To settle matter teacher suggested why not like we give punishment to students? We will take this one person out of this group and let him stand not protected by shed into the open for 5 minute if nothing happen then individual comes back.
The Fear
Because every one feared if lighting strikes due to one person on this tree then many other people who are innocent may get killed.
First They decided Soldier Will go because he may have killed many people in wars he fought. So they pushed soldier in open for 5 minute But nothing happened he returned safely. Everyone was surprised.
Then They all pushed Businessmen thinking corrupt but still he also surprised everyone and came back safely no lighting falling on him. God is not angry with him.
Then they pushed trader may be doing wrong trade due which is attracting wrath of God in form of lighting. But nothing happened in 5 minute.
They Doctor was sent thought was many patient who may have died complaint to god so god was sending emergency response in form of lighting.But he also survived.
Now its turn of Teacher as many people future depends on teacher may have destroyed many career. So he was pushed but nothing happened still.
Then Everyone though its The Women because child cannot be the culprit may be she is politician and its her trade to circulate lies and win votes or may be she is not morally right So She was pushed but nothing happened still.
Everyone Was really surprised So it is this small child Who has committed so much sins that lighting is threatening there purified lifes. So They were standing at crux to push this child to wild open fumes of god wrath and getting consumed by flurry of lighting into ashes.
No one was willing to push child but they decided for the interest of there family and themselves they need to push this child to lightening. So they pushed Child To open area.
As the Child walked into open immediately lighting Strikes.
The Reaction time was limited god’s willingness at test. And bodies turned to ashes. The lighting has fallen not on child but on Tree And 6 people were consumed. Only child survived. You know why?
Due to one child god was protecting all the lighting falling on tree as he has not committed any sins As soon as child walked out. God allowed lighting through tree to pass to rest of 6 bodies for there sins.
So What is Moral of Story? Scientific wisdom says no god Exist but still there is Cause and Effect there is Newton law of Equal opposite reaction. There is Some force controlling universe.The force does react only by testing its willingness and limits.
