It includes pre-built tables that support data import and export in common formats like CSV and XML. Tables can be extended to form parent-child relationships, enabling flexible data modeling and reuse without altering original tables. Show full answer Show less ## Table Administration Administrators have comprehensive control over tables, including creating custom tables tailored to specific business needs, defining field properties, managing table relationships, and extending existing tables. They also set access controls to secure data, implement business rules, and manage table cleanup for obsolete records. Administrators can export and import data to both core and custom tables, facilitating data management and integration. ## Key Features * **Custom Tables:** Expand platform functionality by creating tables and applications that align with unique business requirements. * **Table Relationships:** Establish relationships through table extension, record referencing, many-to-many relationships, and database views for reporting. * **Access Controls:** Restrict user access to sensitive data via defined permissions on tables and records. * **Data Dictionary and System Dictionary:** Access metadata about tables, columns, and fields to aid in data governance and customization. * **Table Management:** Create indexes for optimized data retrieval, delete unnecessary tables, and view visual references of table structures. * **Storage Aliases:** Utilize storage aliases to manage data manipulation and field creation effectively within the platform. ## Benefits for ServiceNow Customers * Leverage pre-built and custom tables to model complex business processes comprehensively. * Maintain data integrity and security with granular access controls and business rules. * Improve data organization and reporting through relationships and database views. * Efficiently manage data lifecycle with table cleanup policies and import/export capabilities. * Enable administrators and developers to customize the platform without impacting core functionality. ## Next Steps To deepen your understanding and effectively manage tables within the ServiceNow AI Platform, explore topics such as managing tables and indexes, working with the Task table, and utilizing database views for reporting. 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 1. Users] {#exploring-table-administration__table_xtm_sly_hcc} ## 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. {#exploring-table-administration__cf-exploring-parent-workflow-ol} ## Table administration benefits {#exploring-table-administration__section_hvn_p4y_mxb} {#exploring-table-administration__table_ivn_p4y_mxb__entry__3} | Benefit | Feature | Users | |-|-|-| | Define models and entity relationships across multiple tables. | [Data dictionary tables](https://www.servicenow.com/docs/Mdb491O~GNpIroWOtz4qPA "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://www.servicenow.com/docs/RZteBXbS87cIDnzTAO3Elw "View table relationships in a visual manner using the schema map.") | Admin | | Store records for your instance. | [Create a table](https://www.servicenow.com/docs/kPmMAEgQaK4x9H5EIGtJZg "Administrators and application developers can create custom tables to store application data.
