  6. Data Manipulation Language (DML) to perform operations on data, including insertions, updates, and deletions

  7. User defined data types (UDTs)

  8. JDBC - Java Database Connectivity

  9. Mapping Structure:

  10. polymorphism - this type of polymorphism is achieved by function overloading or operator overloading

  11. Set, Bags, lists, maps are collection value type

  • Set - HashSet
