• Creating a DATABASE occurrence
• Adding one or more AREA occurrences
• Adding one or more TABLE substructures for each AREA
• Adding one or more KEY occurrences for each TABLE
• Adding one or more ELEMENT occurrences for each TABLE
• Defining one or more FIELD occurrences for each TABLE
• Defining which FIELD occurrences are contained in a KEY
• Defining which FIELD occurrences are contained in an ELEMENT
• Creating DATAVIEW occurrences for use by CA Ideal and CA MetaCOBOL+
• Defining additional attributes for occurrences in the database structure

For more information, additional examples, and the step-by-step procedures to define a CA Datacom/DB database, see the CA Datacom Datadictionary User Guide.

Optional tasks that you can perform in DBMAINT Mode include the following:

• Assigning additional attribute-values for the attributes which are not displayed on the panels
• Designating aliases for the occurrence
• Assigning descriptors to group occurrences for CA Datacom Datadictionary functions
• Retrieving, updating, adding, or deleting the relationships of an occurrence
• Entering free-form, unedited text data to supplement information stored in the attribute-values of the occurrence
• Assigning a lock level to restrict access to an occurrence
• Assigning a password to an occurrence
• Updating the name of an occurrence

When using the processing modes, select a function by entering the option number for that function in the space indicated on the menu panels or enter a command on a command line. A prompter panel is displayed where you enter the keywords for the command. You can skip the prompter panel for a function by entering the full command on the command line.

You can use the following commands in the DBMAINT Mode. For more information and an explanation of each command and the valid keywords, see Online Commands:
