'''Visual DataFlex''' is a [[programming language]] by [http://www.dataaccess.com Data Access], targeted at creating [[database]] and client-server type programs. Visual DataFlex is intended to enable developers to quickly build highly-reliable corporate software solutions and commercial application products with [[Microsoft Windows]], web and [[web services]] interfaces. A Visual DataFlex installation includes visual design tools, a comprehensive [[class_(computer science)|class]] library, a [[compiler]] & [[debugger]], an embedded database, connectivity for leading [[DBMS]]s and a scalable Web Application Server. |

== Architecture == |
|||
Visual DataFlex has a 3-layer architecture: |
|||
;Bottom Layer: Tables at this level represent customer information. Data dictionaries for each table define the rules for saving, editing, deleting, or finding a customer. |
|||
;Middle Layer: Tables at this level represent orders to customers. A ''Data Dictionary Connectivity Object Tree'' defines how tables relate to each other, and ensures that all business rules of the connected tables are in force and validate. |
|||
;Top Layer: A graphical interface ([[GUI]]) that allows users to enter, find, create, modify, or delete data. |
