Record Groups:
A record group is a column-and-row structure stores within Forms Runtime memory and is same to the structure of a database table. It contains records which can be reused through Oracle Developer applications therefore decreasing repeated access to external data.
A Record group can be designed to hold static values. In other words, they can be populated programmatically at run time or, most generally, populated through a SQL query.
Record groups can give the following:
1 Data which is presented through LOVs.
2 Data for dynamic list items
3 Data to be passed to Graphics Builder and Report Builder
4 Other application-defined uses.
