Datatypes Used in Oracle 9i

(Page 1 of 3 )

For those who use databases but are not familar to the Oracle 9i database, perhaps you should read about the datatypes used in Oracle 9i and how they can be used to support object orientation.

It is assumed that you have read my previous Oracle article based on creating an Oracle database in the latest Oracle database 9i. Before we can create a table, one should sit down and take the time to get to know the datatypes available for Oracle.

Also, upon reading articles relating to the Oracle database, you should have come across the term Abstract datatypes. This article will discuss abstract datatypes in depth so that creating a table, which is designed to include abstract datatypes, will inevitably become more understandable. These abstract datatypes, which I like to call user-defined types, are datatypes that behave like objects.
