Sekarang masuk ke Data Architecture

ada 3 metamodel yg mau dibahas dulu

1. Data Entity
An encapsulation of data that is recognized by a business domain expert as a thing. Logical data entities can be tied to applications, repositories, and services and may be structured according to implementation considerations

2. Physical Data Component
A boundary zone that encapsulates related data entities to form a physical location to be held. For example, a purchase order business object, comprising purchase order header and item business object nodes

3. Logical Data Component
A boundary zone that encapsulates related data entities to form a logical location to be held. For example, external procurement information.
