OData Introduction

You can think of the OData service as a database exposed through an HTTP REST interface. When you work with a database you are working with records in a table. You perform one of four operations on the records: create, read, update, or delete. These operations are known as CRUD operations. OData shares this same concept of record manipulation.

An OData service has three basic components, entities (data model types), entity sets (collections), and OData operations. A collection (like a database table) contains instances (like database records) of a specific entity type. Entity types are data structures that are used by collections and have key properties whose values uniquely identify one instance from another. OData operations (like database stored procedures) are pieces of custom logic that you can call. For more information about basic OData concepts, see the OData documentation.
