 What is ODBC ?
--------------------------------------------------------------------------------

   ODBC is the standard proposed by Microsoft Windows for using DataBases
   from any Windows application. You may think about ODBC as we think about
   the Clipper RDD system.

   Clipper RDD system -replaceable Data drivers- is an open architecture
   to be used in Clipper applications. Just for Clipper.

   Windows ODBC system -Open DataBase connectivity- is an open architecture
   to be used in ALL Windows applications.

   As Clipper has an internal engine to support all RDD connections, likewise
   ODBC has a common engine (in ODBC.DLL) which lets all ODBC drivers connect
   easily, using the same way.

   ODBC is supported through a little DLL -about 40 Ks- that serves as an
   interface between Windows applications and any kind of ODBC driver:

    +----------------+   +------------+   +-----------+   +------------+
    |   Your Windows |   |  Windows   |   | Your ODBC |   |  Your      |
    |  application   |-->|  ODBC.DLL  |-->|  Driver   |-->|  DataBase  |
    +----------------+   +------------+   +-----------+   +------------+

  The ODBC driver has to follow the ODBC.DLL rules, so we don't have to
  worry about it as we know that it will always be used in the same
  way. ODBC lets Windows applications use any kind of DataBases in the
  same way!

  FiveWin encapsulates this process and offers you a powerful xBase
  and OOPS management:

    +--------------+      +-----------------+      +------------+
    |    Your      |      |  ODBC Objects   |      |  Windows   |
    |   FiveWin    |----->| easily managed  |----->|  ODBC.DLL  |
    | application  |      | through xBase   |      |            |
    +--------------+      +-----------------+      +------------+

  ODBC.DLL offers a lot of functions to manage different ODBC services.
  FiveWin manages them all with the standard Clipper DBFs management methods.

  We are building a Clipper RDD to manage ODBC, so in future versions of
  FiveWin, managing ODBC will be as easy as:

                USE "MyDataBase" VIA "ODBC"

  Right now we offer a powerful ODBC class to easily manage ODBC. When our
  ODBC RDD is ready, then we will manage FiveWin ODBC objects through the
  Clipper RDD driver.

                Clipper ODBC RDD coming in FiveWin 2.0!
