Data dictionary tables These tables provide data dictionary, data modeling, and entity relationship information: Tables [sys_db_object]: Contains a record for each table. Dictionary Entries [sys_dictionary]: Contains additional details for each table and the definition for every column on each table. Each row represents either a column on a table or a table. Field Labels [sys_documentation]: Contains the human-readable labels and language information. Tables The Tables [sys_db_object] table contains a record for each table in the database. Access the Tables list by navigating to System Definition > Tables. Administrators can create a custom table, add or modify columns in a searchable and sortable embedded list, and define the auto-number format. The following image shows a list of the tables that extend the Task table.Figure 1. Tables Dictionary Entries The Dictionary Entries [sys_dictionary] table, also called the System Dictionary, defines every table and field in the system. It contains information about data type, character limit, default value, dependency, and other attributes of a field. Access the system dictionary in one of these ways: To see the system dictionary list view, navigate to System Definition > Dictionary. To view particular dictionary definition, right-click the list header, form header, or field label, and select Configure Dictionary. The following image shows a filtered list of dictionary entries for the Incident table and the Task table, which it extends.Figure 2. Dictionary Inc Task Field Labels The Field Labels [sys_documentation] table, also called the Language File, contains information about the labels and hints for each table and column in the system. Access the language file in one of these ways: To see the list view, navigate to System Definition > Language File. To see the field label for a particular field, right-click the field label on the form. The following image shows the language file filtered to display only labels on the Incident table.Figure 3. Field Labels System dictionaryThe system dictionary is a table, called Dictionary Entry [sys_dictionary], that contains details for each table and the definition for every column on each table in an instance.Dictionary attributesDictionary attributes alter the behavior of the table or element that the dictionary record describes. Administrators can add or modify dictionary attributes. Modify the Glide durations formatTo convert fields that are displayed in milliseconds (such as 'Resolution Time' on the Incident table) to a duration format (Months/Days/Hours/Seconds), populate the attribute field on the dictionary with: format=glide_duration.
