G Pathmaker and DDL
The Pathmaker product is a NonStop Transaction Services/MP (NonStop TS/MP)
application systems generator. When you start a Pathmaker project, the Pathmaker
program installs a dictionary for you as part of the application catalog, which is an
integrated system directory for the Pathmaker project.
After the Pathmaker dictionary has been installed, you can start a DDL process from
within the Pathmaker environment and enter definitions and records just as if you had
created the dictionary from the command interpreter; however, there are differences in
the information stored in the dictionary and this affects the way the dictionary is
maintained.
DDL is used to specify definitions and records used by Pathmaker dictionaries. The
DDL compiler can add these objects to and delete them from the dictionary, as well as
perform other operations on them. The Pathmaker product contains other objects in its
dictionaries (servers, services, requesters, and screens) that are not defined by using
DDL. Only the Pathmaker software can add these objects to or delete them from a
Pathmaker dictionary (or catalog). In addition, a Pathmaker dictionary contains
application design information provided by the Pathmaker product, not by DDL.
