The Black Box Approach
In our Signal and Systems course we saw Electric Circuits. There are famous Circuits called
Thevenin and Norton Equivalent curcuits. These Circuits formed from complex circuits.
You calculate the tendency of the complicated circuit and replace all circuit with one current
source and one resistor. Put it inside a black box. Since you do not need to know the all circuit
only behavior is needed so simplify it and cancel the rest.We can't see complicated circuit since All the staff is inside the Black Box. All the thing we saw is 1 resistor and 1 current sourrce or 1 Voltage source.
But This Time situation is a bit strange since Devoloppers are made to behave database software
as a black box Altough Database is the most important point of the system. This means Do not know what is inside, do not try to understand it use it as a
data storage and do your coding staff.
This section simply tells that this is completely wrong. Devoloppers can not behave Database software as a black box.
They should know how the application running inside the database.If not when they face with error
they(devoloppers) will be in deadlock. All of them will look each other or one computer.
And he tells one of his experience about such condition in this section. He has such an interesting devoloppers that
when he wants documatation in the time of Oracle 7.3 They give him Oracle 6.0 document. :)
From diiferent perspective if we look to the issue we can see that how will devoloppers job become easier if they realize What database provide for them. With this understanding Performance will also increase.Shortly it is suggested that : Understand your database, Know how it works, Know what it can do for you, And use it to its fullest potential.
