Defining the Database

Data definition involves specifying the structures for the database and object

definitions, and recording them in a data dictionary for the application. You can

specify ENSCRIBE files, record structures, and data structures through standard DDL.

Alternatively, you can make NonStop SQL tables available to your application by

registering them with PATHMAKER. Both of these operations are available from the

main menu. The PATHMAKER catalog uses your database definitions to help you in

the development process.

Defining the Requester

A PATHMAKER application can support various requesters that generate menus,

accept data from users, or invoke services to process data. Certain kinds of requesters

can even invoke servers developed outside of PATHMAKER if those servers are

registered with your project.
