Being a developer we have to write several files which contains source code.

Developer  Write Code  Files

Client gave requirement to Durga to develop a project

client project

|--100 files developed

|- client suggested some changes

|- I changed some files source code to meet client requirement

|- I gave the demo and client suggested some more changes

|- I changed some files source code to meet client requirement

|- I gave demo 3rd time

|- Client asked for first version only

|- My Face with big ????

We should not overwrite our code.

Every version we have to maintain.

1) Maintaining multiple versions manually is very complex activity.

2) Dev-A and Dev-B working on the code. At last we have to merge the code developed

by both developers and we have to deliver to the client. If both developers developed

a file named with Util.java, then one copy will overwrite with another copy, which

creates abnormal behaviour. We should not overwrite our code.

Git For DevOps

2) Every change should be tracked like

who did the change

when he did the change

which changes he did etc

and all changes should be maintained.

3) Overwriting of the code should not be happend.

4) Developers have to share their code to peer developers, so that multiple developers

will work in collaborative way.

5) Parallel development must be required
