Operating a DB Requester Application
A DB requester application uses keys to locate specific rows (records) in a database.
Three categories of keys exist for NonStop SQL tables:
Primary keys
Indexes
SYSKEYs
Three categories of keys exist for Enscribe files:
Primary keys
Alternate keys
Courtesy keys
DB requester applications generally use primary keys and indexes (alternate keys) to
locate information in the database. Courtesy keys cannot be used, and SYSKEYs are
not generally used.
As with most other end user screens created with the Pathmaker product, a DB
requester application screen contains a title area, a data field area, a function key list,
and a message area. If an asterisk (*) appears to the left of a data field heading on the
screen, it identifies a primary key field. If a plus sign (+) appears to the left of the data
field heading on the screen, it identifies an index or alternate key field. The end user
indicates to which row(s) an operation applies by entering data into these key fields on
the screen.
