database. We use VSS to managing version of an application.

modification we consider that as a new version of that 
application. We kept our old version and this new version 
of application in our database. We use VSS (Version source 
System) to manage the verions of application

Charan Teja VSS Stands for Visual Source Safe , Yes it's a

Here Mainly 2 terms is there one is Check in & another one 
is Check out.

Check in Means what ever changes we made to the coding or 
build etc.. that will apply to Main Server.

Check Out Means we will get the latest version of files.

So initially when we are entering in to VSS first time we 
have to click on Check out option...to get the latest 
Version files . After any modification done by you then 
click on Check in that changes will apply to Main Server..
