What is type in SAP Commerce?

A type is a template for objects. 

SAP Commerce uses a system of types to organize data, for example product information, customer data, addresses, or orders.

Types define persistent objects in several aspects:

• attributes manage and store data for the object,
• the deployment defines the database table the object is stored in.
• the Java class of the object.

An object instance of a type is called an item:

Platform concept	Java concept
type	class
item	object / instance

A Type is the type definition in items.xml and its Java implementation.
