Is Sybase 11.0.3 a Relational DBMS or an Object-Relational DBMS? Can I create object like in Oracle 8+?

Can I connect to Sybase 11.0.3 using C++ or Java? What libraries do I have to use and where can I get it?

What are the differences between Sybase, Oracle and PostgreSQL in term of querying? Are they the same?

Best Regards
