1. Prerequisites

• Basic knowledge of the eMagiz platform

2. Key concepts

This microlearning centers around understanding the difference between CDM and CDM messages. By CDM we mean: The Canonical Data Model that plays a vital and central role while exchanging data between various systems via the messaging pattern

• The complete CDM consists of the collection of entities that are used or going to be used in the various CDM messages

3. Difference between CDM and CDM messages

Simply put the difference between the CDM and the CDM messages is as follows:

• The CDM holds all entities and attributes that are relevant within the context of your complete integration landscape.
• The CDM message is tailor-made for a specific piece of data (i.e. Order, Invoice, Employee) and only holds the entities and attributes relevant for that piece of data.

So that means that when you navigate to Design -> CDM you will see everything

Afterward when you zoom in on one of the available message types to create or view your CDM message the overview changes to show the structure of the message and to show which parts of the CDM are used for the CDM message.

Practice

4. Assignment

Open the CDM of your (Academy) project and subsequently open one of the CDM messages that are created within your (Academy) project and spot the differences. This assignment can be completed with the help of your (Academy) project you have created/used in the previous assignment.

5. Key takeaways

• The CDM holds all entities and attributes that are relevant within the context of your complete integration landscape.
• The CDM message is tailor-made for a specific piece of data (i.e. Order, Invoice, Employee) and only holds the entities and attributes relevant for that piece of data.
