The CrystalNet Technologies LTD company has released a new version of the ADO.Net VCL for Delphi v4.0.0.0.

ADO.Net VCL for Delphi is the fastest and most reliable database connectivity solutions for any database using ADO.Net technology in Delphi. It provides data access to data sources such as SQL Server, Oracle and to data sources exposed through OLE DB and ODBC using ADO.Net data provider framework. ADO.Net VCL for Delphi is an enterprise solution with highest performance and unlimited possibilities. Data-sharing consumer applications can use ADO.NET VCL for Delphi to connect to these data sources and retrieve, handle, and update the data that they contain.

With its powerful common architecture base on ADO.Net technology, ADO.Net VCL for Delphi enables high-speed direct data access from Delphi to SQL Server, Oracle and other data sources exposed through OLE DB and ODBC.

This article summarises basic requirement and key new features and improvements in this version. This VCL is a new design and implementation and the design architecture is different from the previous version.
