[Microsoft.ACE.OLEDB.12.0 data provider]: Used by Microsoft Access And as an integrated and improved ACE engine whose development started by taking a code snapshot of the original JET code base and upgraded to support 64-bit version and to enhance the integration with SharePoint related technologies and Web services generally.
Prior to Access 2007, Access used theMicrosoft Joint Engine Technology (JET)` engine. However, with Access 2007 release the JET engine was deprecated and is no longer distributed with MDAC. Instead, Access now uses an integrated and improved ACE engine whose development started by taking a code snapshot of the original JET code base.
The ACE engine is fully backward-compatible with previous versions of the JET engine so that it reads and writes (.mdb) files from earlier Access versions. Because the Access team now owns the engine, developers can be confident that their Access solutions will not only continue to work in the future but will also be faster, more robust, and feature rich. For example, with Access 2010 release, among other improvements, the ACE engine was upgraded to support 64-bit version and to enhance the integration with SharePoint related technologies and Web services generally. Microsoft is committed to Access as a developer platform.
