Opf3 v3.0.2 Review

Opf3 is an object persistence framework for .NET 2.0 that provides a large set of sample/tutorial projects for you to see how the framework works. Opf3 uses code attributes and reflection to handle the mapping of Object fields to database table columns. The vendor's Web site has a PowerPoint tutorial that shows how to make use of the framework for creating and persisting objects using the Opf3 framework. The samples we downloaded require Visual Studio 2005 and can not be opened by Visual Studio 2003. Database support is strong as the Opf3 framework supports Microsoft SQL Server, Oracle, VistaDB, Postgre SQL, Microsoft Access, and Pervasive SQL. OPath is the object query language used by the Opf3 framework and supports raw SQL for sorting and grouping purposes. Support for Opf3 is provided via e-mail and annual priority e-mail support is available for purchase from the vendor's Web site.
