Detailed Explanation:

In ServiceNow, thesys_idfield serves as a unique identifier for every record within the platform’s database. The sys_id is a 32-character globally unique identifier (GUID) that ServiceNow automatically generates for each record, ensuring that every record is uniquely identifiable and can be referenced across the system. This sys_id is essential for integrations, queries, and relationships between records. (Reference: ServiceNow Documentation - Record Identification and sys_id Field)

✔Client-side Scripting:UI Policies, Client Scripts

✔Server-side Scripting:Business Rules, Script Includes, Scheduled Jobs

✔Workflow & Flow Designer:Custom scripts for approvals, conditions, and notifications

✔Integration Scripts:REST API, SOAP API calls

TheConfiguration Management Database (CMDB)inServiceNowstores information aboutconfiguration items (CIs)and theirrelationships.

cmdb (Configuration Management Database)The main parent table for all CMDB-related data.

Storescore configuration item (CI) data.

Other CMDB-related tables inherit from this table.

cmdb_ci (Configuration Items Table)Stores individual configuration items (CIs).

Every CI (e.g., servers, network devices, software) is stored in this table or one of its child tables.

This tableextendscmdb.

cmdb_rel_ci (CI Relationships Table)Stores relationships between CIs.

Defines how CIsconnect to each other(e.g., "server hosts application").

Helps withService Mapping and Impact Analysis.
