Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Visual DataFlex is a 4GL windows programming language by Data Access, targeted at creating database and client-server type programs. Data Access Worldwide of Miami, USA is the company behind the studio and language and built its business up around the console mode DataFlex language which was released prior to DOS and competed with dBase II in early microcomputer technology. The first attempt at a windows product was DataFlex for Windows which failed as it was a sort of windows bolted on top of DOS product. Then they released Visual DataFlex 4.0 in 1997 which allowed users to write native 32 bits Windows applications. Every 6 months a new revision level is released. Visual DataFlex is now in revision 15, named VDF 2009, and features a datadictionary layer of business rules which is of dual use with the windows product and the webapp extension.
