hi, we will use this pattern when we want to make our beans independent of the database. If u don't know exactly which database u r going to use in application then u will use this pattern. U can get the interface to the instance of the database type of object (ex: oracle, sql server etc.) from the factory depending upon the requirement. U can set which database u r going to use using the properties file (.java) . refer to the petstore 1.1.2 version.
