Object-To-Relational Database-Mapping Tool Optimizes Java Persistence



Thought Inc. says its object-to-relational database-mapping software--CocoBase Enterprise O/R--has been integrated with the BEA WebLogic Server 6.0 from BEA Systems Inc. This brings to eight the number of Enterprise JavaBeans-compliant servers that CocoBase supports. The database-mapping product is optimized for EJBs and eliminates the need to hand-code database access for EJB Entity beans and Java Server Pages.

CocoBase uses a mapping facility to create a database table that maps from one-to-many, or many-to-one, to generate the code for EJB Entity beans and Session beans, with either Container Managed Persistence (CMP) or Bean Managed Persistence (BMP)--the standardized ways Java handles persistence in databases. This can save a developer up to eight hours of hand coding for a CMP Entity bean and 40 hours for a BMP Entity bean.

In addition, because CocoBase comes from the world of object-oriented design and modeling, and includes many best practices that have been built into its mapping techniques, the product acts as an optimizer for enterprise Java. It uses patterns to overcome the performance problems that commonly occur at the persistence level when scaling Java for the enterprise.

The other product advantage is one of flexibility and the ability to make changes to the system quickly, including changing the database. Maps containing the persistence models are independent of the database and are portable across different EJB-enabled application servers, so they can be easily modified to change patterns when either the enterprise applications or the system components require it.

Depending on the technology and configuration being used, CocoBase has been shown to make processing time on an EJB server 30 to 40 times faster.
