Lesson Aim

This lesson teaches you how to enable Web applications to query, insert, update, or delete data in the database. You learn how to use ADF BC read-only view objects to provide a reusable mechanism for defining database queries. The entity object is the ADF BC mechanism for persisting data. You create entity objects from selected tables in the database schema and then create updatable view objects based on them.
