I am a new customer, looking forward to great experiences.

Skills are C# programmer with lots of DBA (MS SQL, Oracle, PostgreSQL) experience.

I wish to create REST based API on existing relational data stores (3 above), which features of LLBLGen Pro will get me going quickest?

Which examples? What to read? Ideas and/or suggestions?

I need my REST API for query 70%, update 10%, create 20%, and seldom delete.

Thank you.

Are you looking for using OData or RIA services or your own?

I wish to publish only OData services myself, but thinking out a bit farther I might also consume proprietary services. So, initially, OData services.
