DB Analogy

QT:
(Proverbs:30-34)
30 I walked by the field of a lazy person,
the vineyard of one with no common sense.
31 I saw that it was overgrown with nettles.
It was covered with weeds,
and its walls were broken down.
32 Then, as I looked and thought about it,
I learned this lesson:
33 A little extra sleep, a little more slumber,
a little folding of the hands to rest—
34 then poverty will pounce on you like a bandit;
scarcity will attack you like an armed robber.

When there is work to be done it got to be done,
When you need a break have it and take no extras.

Take Away:
from lec: meant to be fun!!
My DB lecturer came with a captivating analogy to illustrate the concept of Transaction States in a DB which he claims is boring.

A transaction invoke commence to an active state having read and write operations.Like guys busying studying at school.Some dare not approach girls for they fear that they will be rejected and end up a failure, like a transaction getting aborted to a failed state.

Some guys are daring and goes out to woo the girl and hence like the transaction become partially committed but still the girl can say 'NO' and the transaction aborted to a failed state.If the girl say 'YES' then the transaction end to a committed state.

All love story comes to an end and transaction end up being in a terminated state

Part2

Many guys can go after a girl resulting in a multiple transaction states resulting
in lots of problem.There is a tendency that the most recent guy will be accepted for
he learns from the previous guys and better himself before the girl.The current most transaction gets executed skipping the earlier ones.

Lecture will be fun with such analogy don't you agree?
