5. Comparison between HFSQL and CEDB
Previous pageTable of contentsNext page
To display information coming from a database in a window, the controls of this window must be linked to the different database items.
The method for displaying and retrieving information depends on the database used (HFSQL or CEDB).
File link between a window and an HFSQL database
In most cases, the link between a control and an item is defined in the window editor when describing the control ("File" tab). This link allows you to specify the file item that will be used by ScreenToFile and FileToScreen.
File link between a window and a Pocket PC database (CEDB)
This link must be defined by programming (cdbXXX functions).
Other differences
Using HFSQL databases (Classic or Client/Server) gives you the following advantages (non-exhaustive list):
  • Speed of the HFSQL database.
  • Queries on HFSQL databases (created with the query editor included in the product).
  • Fast application development via Full Application RAD.
  • HFSQL-specific features (encryption, etc.)
