  1. RDB – OODB - ORDB Comparison

  2. RDB • Simple data model (but less versatile) • Simpler for user to learn (OO programmer?) • Easier to optimize (for simple access?) • Strong market-share (inertia of change)

  3. ORDB – OODB Similarities Similar OO type system ambitions: Objects/OIDs Methods ADTs Constructed types Inheritance Object-QL

  4. Advantages of Adding OO • Richer Data Types • Simplify DB design • Simplify query specification • Reusability of code (more natural to OO programmer) • No impedance mismatch

  5. ORDB Extra Goodies DBMS features inherited from RDB into ORDB : • Constraints • Views • Triggers • Priviledges (security)
