Acquia Source structures data with the following primary entity types:

*   Content
    
*   Media
    
*   Taxonomy
    
*   Menus
    

An entity represents a distinct, manageable piece of information or content within a system. Each entity type is further categorized into one or more bundles. The terminology for these bundles varies depending on the entity type. For example, a bundle within the Media entity type is called the Media type bundle, and a bundle within the Taxonomy entity type is called the Vocabulary bundle.

The following table provides detailed information about entity types:

In Acquia Source, you can customize any bundle for any entity type and can also create new bundles.
