# Data Model

Entity relationship diagrams (ERDs) for standard Salesforce objects illustrate important relationships between objects. Salesforce ERDs use crow’s foot notation.

#### Note

ERDs are hosted in the [Data Model Gallery](https://developer.salesforce.com/docs/platform/data-models/guide). The Salesforce Data Model Gallery is a curated collection of diagrams that illustrate the underlying data models for Salesforce products, features, and clouds. It’s a resource designed to support customers, developers, solution engineers, and data architects in understanding how data is structured across Salesforce — enabling better solution design, integration planning, and implementation strategy.

The data model for your custom objects depends on what you create.
