Why Do Application Developers Need ADO.NET?
ADO.NET provides a comprehensive caching data model for marshalling data between applications and services with facilities to optimistically update the original data sources. This enables developer to begin with XML while leveraging existing skills with SQL and the relational model. Although the ADO.NET model is different from the existing ADO model, the same basic concepts include provider, connection and command objects. By combining the continued use of SQL with similar basic concepts, current ADO developers should be able to migrate to ADO.NET over a reasonable period of time.
