Although Java is truly an object-oriented language, applications that access relational databases must deal with tables, rows, and columns. This forces a developer to work with two different models, an object model and a relational model. Developers must write tedious routines that convert rows and columns into Java objects. This is known as the impedance mismatch between Java objects and relational databases. VBSF contains an object-relational mapping engine that automatically implements object persistence to relational databases , allowing a programmer to forget about JDBC and stay focused on the object model.
Local objects are fully scaleable to a three-tier configuration with no source code changes.
With the distributed version of VBSF a developer can deploy persistent classes in a three-tier configuration. Clients communicate only with the middleware layer without worrying about database issues. Powerful applets that access databases can be created without the need to import any database drivers.
