Components of a DB Requester Application
A DB requester application is composed of:
One or more DB requesters that application developers create using the
Pathmaker product
The standard services and servers provided by the Pathmaker product
One or more menu requesters that application developers create using the
Pathmaker product (optional)
It is possible to create a DB requester application that accesses:
Only one table or file (a single-file DB requester)
Multiple related tables or files (a multifile DB requester)
NonStop SQL tables and Enscribe files, however, cannot both be accessed by a single
DB requester.
DB Requester. A database (DB) requester displays a screen that end users can use to
enter, retrieve, or modify data in a database. Only a DB requester can be used to
invoke the standard services provided with the Pathmaker product.
Note DB requesters cannot use custom or registered services.
Standard Service. Standard services perform common database functions such as
inserts, deletes, and updates. These services are packaged into two standard servers
provided by the Pathmaker product—one for use with NonStop SQL databases and
one for Enscribe files.
