What is Build -in Strategy in BO?

DESIGNER uses the following built-in strategies for creating the components of universes:

• The Objects Creation strategy, which tells DESIGNER how to define classes and objects automatically from the database’s tables and columns.
• The Joins Creation strategy, which tells DESIGNER how to define joins automatically from the database’s tables and columns.
• The Table Browser strategy, which tells DESIGNER how to read the table and column structures from the database’s data dictionary.
