Object Services
Object Services is an object orientated framework for working with relational databases. Instead of working directly with Open SQL statements , persistent objects are used whose attributes are mapped to database content. In this way the actual database access is encapsulated by the classes and interfaces of Object Services.
Object Services provide the following sevices for handling persistent objects on the database:

Persistence service

Transaction service

Query service

Persistente objects are based on
persistent classes . The creation of persistent classes is supported in Class Builder by generating an object-relational mapping using the attributes of the class and automatic creation of associated class agents.
