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.

## Table administration overview {#exploring-table-administration__section_jdy_4z4_4xb}

The ServiceNow AI Platform® uses a table-based data structure to store and organize information. Pre-built tables are included for common IT service management (ITSM) processes, with their data fully importable and exportable
in CSV, XML, or other formats.

## Table administration users {#exploring-table-administration__cf-exploring-parent-users}

{#exploring-table-administration__table_xtm_sly_hcc__entry__2}

| User | Description |
|-|-|
| Administrator | Admins can create custom tables for specific business requirements, define field properties, create relationships between tables, and extend existing tables without modifying the originals. Administrators also define access controls to allow only approved user access to records, business rules for various tasks, and table cleanup policies for unused and outdated records. |

## Table administration workflow {#exploring-table-administration__cf-exploring-parent-workflow}

This infographic depicts how an administrator can extend both core tables and custom tables.
Figure 1. Extending core tables and custom Tables  
1. An administrator views table relationships and learns how table extension works on the ServiceNow AI Platform®.
2. The administrator creates a custom parent table and extends it by creating a custom child table.
3. The administrator defines access controls to restrict access to each table.
4. The administrator exports and imports data to core and custom tables as needed.

| Benefit | Feature | Users |
|-|-|-|
| Define models and entity relationships across multiple tables. | [Data dictionary tables](https://servicenow-prod.fluidtopics.net/3EZteVtyj81twU5KSs6fXw "Access details related to tables, columns, and field labels in your instance.") | Admin |
| Access visual references for tables and their contents. | [Viewing table references and extensions](https://servicenow-prod.fluidtopics.net/TFWFPZctaar_WohEyqeaQQ "View table relationships in a visual manner using the schema map.") | Admin |
| Store records for your instance. | [Create a table](https://servicenow-prod.fluidtopics.net/ytA17q3swveAExCTp20wmQ "Administrators and application developers can create custom tables to store application data. After you create a table, you can also modify field types and field labels.") | Admin |
| Remove unneeded tables from your instance. | [Deleting custom tables](https://servicenow-prod.fluidtopics.net/pl_2z4Ew0M9kLUZOFoAdMQ "Administrators can delete custom tables that are no longer needed. For example, delete a table from an application that is under development because the business requirements change.") | Admin |
| Quickly find data stored in a table. | [Create a table index](https://servicenow-prod.fluidtopics.net/w8kbQwpMpCH1Qn9dAI6jpA "Build indexes to access the data held in your tables more easily.") | Admin |
| Connect a list to another list of multiple entries instead of a single field. | [Create a many-to-many table relationship](https://servicenow-prod.fluidtopics.net/Cm0P7RQJbt7QKf5LcKDTSw "Create a bi-directional relationship between two tables, so that the related records are visible from both tables in a related list.") | Admin |
| Organize and store task-related data. | [Working with the Task table](https://servicenow-prod.fluidtopics.net/6HWd5t7MFT68WrB7qCnqmA "The Tasks [task] table is one of the core tables provided with the base system.") | Admin |
| Connect tables for reporting purposes. | [Working with database views for reporting](https://servicenow-prod.fluidtopics.net/GAUmTRa6UAEIxsWSMFYg2g "A database view defines table joins for reporting purposes.") | Admin |

{#exploring-table-administration__ul_b5m_sly_hcc}
* **[Custom tables](https://servicenow-prod.fluidtopics.net/SehPmHDWDfxzAhX4D5JZgQ)**   
  Custom tables enable you to expand the functionality of the ServiceNow AI Platform and create custom applications.
* **[Data dictionary tables](https://servicenow-prod.fluidtopics.net/3EZteVtyj81twU5KSs6fXw)**   
  Access details related to tables, columns, and field labels in your instance.
* **[System dictionary](https://servicenow-prod.fluidtopics.net/4a2v7eTS8qFMt~3PiE0b7w)**   
  View a list of all tables in columns in your instance from the system dictionary.
* **[Table relationships](https://servicenow-prod.fluidtopics.net/IlDkn8H8WGxMI8S8nkMKKw)**   
  You can create relationships between tables by extending tables, referencing records in another table, creating many-to-many relationships, and joining tables in a database view.
* **[Table extension and classes](https://servicenow-prod.fluidtopics.net/OTDxMr0wkFNHki~r9MEyVA)**   
  Enable one or more child tables to share fields and records with a parent table. Administrators and application developers can only extend tables during table creation.
* **[Storage aliases](https://servicenow-prod.fluidtopics.net/ZKewdBrM1_BndWZ8ctToKg)**   
  Learn about the role storage aliases play in data manipulation and field creation in the ServiceNow AI Platform.
