Release 10.1A: OpenEdge Development:
Progress Dynamics Basic Development

Summary

This chapter has described the structure of the SDO and how you can add business logic to the SDO to validate data in what will most commonly be a single-table update plus updates to related tables on the server. It has also shown you how to define messages in the Repository and use them in your application.

For a description of more advanced business logic, see Chapter 11, " Building Advanced Business Logic in a Progress Dynamics Application." It covers the following topics:

Information on using the SmartBusinessObject (SBO) to define an update spanning multiple, related tables that are modified on the client and then saved as part of the same transaction.
Other techniques for handling parent-child record display and update in a single transaction.
Guidelines for using database trigger procedures as part of your application logic.
A description of how to build SDOs that operate against a temp-table created on the server rather than a database table.
Writing your own custom business logic procedures to run on the server, and invoking those from client application code.
