Entity Objects in Oracle OAF

  • Entity Objects map to a Database table or other data source.
  • One EO represents one table in database but in some cases one EO may represent several tables.
  • Each Entity Object instance represents a single row.
  • Entity Objects are fundamental BC4J objects through which all inserts/updates/deletes interact with the database.
  • Entity Object contain attributes representing database columns.
  • Entity Objects are the central point for business logic and validation related to a table.
  • Entity Objects encapsulates attribute-level and Entity Level validation logic
  • Entity Object can contain custom business methods also.
  • We will not modify Oracle Provided Entity Objects directly but we can extend EO.
