### SmartAgent family

We are committed to serve the Object Technology community by providing a series of high quality middle ware components which allow application developers to focus on their business solution instead of infra-structure details. Our series of SmartAgent components come as the traditional Smalltalk classes structure and VisualAge's Part interface, one can easily wire up the SmartAgent inside the VisualAge composite editor.

#### Object Persistent Agent - $ FREE

Provides an easy and flexible mechanism to store and retrieve Smalltalk objects into/from relational databases. Supporting DB2/2 and ODBC databases, working in OS2, Windows NT, Windows 95 environments.

Traditionally, storing Smalltalk objects into RDBMS either requires hard coded SQL statements embedded into the application, results to virtually zero reusability. With the Object Persistent Agent, developers need only write two simple methods to define a "Persistent Schema" and "Object Schema" in the class which requires persistent, the agent then takes care of all, there is no special programming effort or change in application logic required.
