Table administration

Table administration

A table is a collection of records in the database. Each record corresponds to a row in a table, and each field on a record corresponds to a column on that table.

Applications use tables and records to manage data and processes, such as Incident, Problem, and CMDB. Tables can extend other tables, creating parent tables and child tables.

Watch this nine-minute video for an introduction to tables, records, and fields in ServiceNow®.

Administrators can use these tools for viewing and modifying the database structure:

  • Tables module: Provides a list of all tables in the database.
  • Tables & Columns module: Provides a list of all existing tables, with columns, column attributes, and indexes.
  • Schema map: Provides a graphical representation of the relationships between tables.
  • Data dictionary tables: Contains additional information that defines database elements.

Changes to site functionality will be made starting around 6am on January 21st (Pacific Time) and lasting approximately 6 hours.  The site may be intermittently unavailable.
