How to Construct My Memento (Cont.)
  1. Oracle9i (Object-) Relational Database Design Database design uses either one of the following two methods:

    • Entity-relationship modeling, dividing your database in two logical parts, entities (such as “customer” and “product”) and relations (such as “buys” and “pays for”).

      •
    • Normalization, a series of steps followed to obtain a database design that allows for efficient access and storage of data in a relational database.
