DDL/DML Version Control - forum topic by pawankumarjha

Hi Teradata Gurus,
I am relatively new to Teradata and using Teradata ver 13 SQL assistant. I need to verify from the experts whether there is any version control in place in Teradata for the code we develop. For example, if I modify a table 5 times adding some columns each time, Can I see all these DDL/DML versions at a place for that table/view/macro/etc.?
If this feature is in place, please share how to get this. If not, then what is the process we can use to get all the versions of DDL/DML for a table/view/macro?
Thanks in advance,
Pawan
