Hi,
Is there a way to do version control in Datastage.
If not, do tools like SVN and other third party tools support Datastage versioning as well.

Asked and answered several times here already as an exact search for "version control" will turn up. A recent example is here, there are a number of others.

And to your second question, yes, there is an interface to source code control systems via their Eclipse plug-in and the Information Server Manager client.
