Answer 1

Hi Saichand,
Let me contribute a little,
1. For doing transformation you need to have source and target connections right,topology manager is for defining the connections, basicaly to set the connection environment.
2. Not required as the name implies its a demo environment. Once you created repositories you can go ahead in doing transformation.
3. Repositories are not in files structures, its metadata structure. Master / work repositories are stored in your underlying DB ( you can see some tables in your master and work repos locations)
Master : All your topology, security manager works goes here.
Work : All your design, operator works/metadata goes here.
4. Interface is for building mappings, doing transformations but in one interface you can have ONLY ONE target.
5. No idea. :), google.
Let me know if its clears.
Thanks,
G
