Visual DataFlex is a "transparent" front end tool, being able to interface with most backend types including the included free embedded DataFlex tables, MS-SQL, IBM-DB2, and Oracle, etc. |
|||
== 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. |
