Record Display
The ‘View Data’ window lists records for the selected file. Double click on a single record invokes a
window displaying full record display.
Select the record ‘Bertwhistle & Company Ltd’ and perform double click on it. This invokes a window
displaying record display along with the records for its dependents.
Record Display with Dependents
Note the tabs below the record display – Contacts and Purchases. These are the dependent tabs
showing the dependent data. The ACCESSES/OWNS relationships for the file ‘CUSF’ in the Data
Model Diagram is seen in action here. ‘CUSF-Sites’ owns ‘CNTACS-Contacts’ and ‘CUSTS-
Purchases’ and hence the two appear as dependents.
The ACCESSED BY relations is depicted by the ‘Descriptors’ button on the record display. This can
be understood as JOIN to a foreign file to get the description for the code used from the
Master/Owning file.
