Answer / vijayvardhan

For integrating the modules we have three techniques or approaches. Which one we have to follow is depends on the source code availability.

Three techniques are
1.Bing Bang approach
2.Top - Down approach
3.Bottom-Up approach

>Bing bang approach can be choosed when all Units are available without any incompletion in programming.
>Top-Down approach can be choosed when any in completed program at bottom level while integrating the modules. Here integration can be done from top to bottom. and incompleted program can be replaced with "Stub"
>Bottom-Up approach can be choosed when any in completed program at top level. Here integration can be done from bottom to top and the incompleted program can be replaced with "Driver"

Correct me if am wrong.
