3. The product should be favourable to generate flat files as output (minimum ) (if it support other types it is well and good)
4. Before that we need to have define our own business ,transformation rules .
5. Also we need to have an option of printing the business rules and transformation rules.
6. Generate the code
7. user management should be there.
