+# ServiceNow Automatic Relationship Builder  
+**Auto-create CMDB relationships dynamically on CI insert or update**
+
+---
+
+## Overview
+
+The **Automatic Relationship Builder** ensures that your CMDB stays complete and accurate by automatically creating parent–child relationships between Configuration Items (CIs) whenever they are inserted or updated.  
+
+Instead of manually linking servers, applications, and databases, this Business Rule dynamically establishes **"Runs on"**, **"Depends on"**, or **"Connected to"** relationships based on CI attributes.
+
+---
+
+## Key Highlights
+
+Builds CMDB relationships automatically  
+Eliminates manual linking of dependent CIs  
+
+---
+
+## Use Case
+
+When a new **Application CI** is created or discovered and its **host CI (server)** is known,  
+the script automatically builds a relationship of type **“Runs on::Runs”** between the two.
+
+This keeps your CMDB up-to-date without human intervention.
+
+---
+
+## Table and Trigger
+
+| Item | Value |
+|------|-------|
+| **Table** | `cmdb_ci_appl` |
+| **Trigger** | After Insert / After Update |
+| **Condition** | `u_host` field is populated |
+| **Purpose** | Create a “Runs on” relationship between host and application |
+
+---
+

+| Owner  | IT Operations                |
