An Object [data] Dictionary description is a programming object. The descriptions in DDDescriptions are available for use by special development tools, either those potentially available from Zim or those created by the application developer.

Establishing a Description

Call up the Development Center with the DC command, select DDDESCRIPTIONS from the OBJECTS drop-down menu, and use the tools of the Development Center to define the desired description.

Fields of the Descriptions Entity Set

The name of a user.

The name assigned to an end-user.

Valid Values

An 18-character string, containing a valid object name

Remarks

Each UserName must be unique. Unlike other attributes in the Object Dictionary, UserName is case-sensitive.

When you use the New Database (ZIMINIT) utility to initialize a new database, two UserNames are automatically added to the Users entity set. These names are super and ZIM. Both of these users have 0 for a UserId and 0 for a GroupId.

You may change or delete the super and ZIM entries; take care, however, as changing or deleting the ZIM entry may make the database inaccessible!

Only a “super user” (i.e., a user whose GroupId is 0) can view or update the Users entity set.
