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.
[edit] 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.
