Features

• A server object-cache which
  • reduces access to the database
  • prevents unending loop reads when retrieving objects involved in a circular or bi-directional relationship
  • is designed to be extended.
• Mapping support for 1:1, 1:n and m:n associations
• Support for polymorphism and extents via various pattern (single table inheritance, table inheritance, concrete table inheritance, )
• Designed to support one class to n table mapping
• Sequence managing with Id buffering (limit database access)
• Optimistic concurrency support (Designed to support pessimist offline lock and coarse grained locking strategies)
• Non intrusive framework : persistence behaviour is added using runtime Aspect weaving
• Object framework query support. In other words, it provides SQL query abstraction (it does logical to phycal filed mapping during evaluation thus decoupling Queries from physical model)
• Automatic generation of insert, update, delete on trancsaction commit
• Lazy loading for object graph via ghost object pattern
• XML file based configuration to define the O-R mapping
• Transaction boundaries (units-of-work) defined by PersistenceFactory lifetime. Transaction management based on COM+ enterprise services
