Version 2.0

ODBC Desktop Database Drivers 2.0 was released in December 1994. These drivers were released for use with ODBC 2.0, which significantly expanded their ODBC functionality. The major change in version 2.0 was that the Microsoft Jet database engine replaced the SIMBA query processor. There were many advantages to this:

• With the Microsoft Jet database engine, the Desktop Database Drivers integrated much more tightly with the Microsoft Jet installable ISAM drivers and Microsoft Access technology.
  
  
• The Microsoft Jet cursor model offered significant improvements over the SIMBA model, which used the ODBC Cursor Library to provide scrollable cursors. Microsoft Jet provided native support for scrollable cursors.
  
  
• Microsoft Jet provided native support for outer joins, updatable and heterogeneous joins, and transactions.
  
  
• The Microsoft Jet query optimizer, with enhancements such as Rushmore technology, dramatically increased driver performance.
  
  
• Microsoft Jet provided 32-bit versions of the drivers for Microsoft Windows NT.
