Release 10.1A: OpenEdge Development:
ProDataSets

ProDataSets and Microsoft ADO.NET DataSets

ProDataSets map very closely to the ADO.NET DataSets defined by Microsoft as its new standard for data access. This allows you to pass a ProDataSet from Progress to .NET (by way of the new support for .NET in the OpenEdge 10 Open Client) and have it received as an ADO.NET DataSet with no loss of either data or definitional information. The same DataSet can then be passed back to business logic on a Progress AppServer, which can process changes and write them to the database.

In this way the ProDataSet extends both the power of expressing business logic in the Progress 4GL and the requirements for open applications that can be partitioned between Progress and other technologies such as .NET.
