10
11 To conclude our section on microlearnings that all have something to do with the CDM we wrap things up by learning what the difference is between CDM and CDM messages.

18 == 1. Prerequisites ==
19
20 * Basic knowledge of the eMagiz platform
21
22 == 2. Key concepts ==
23
24 This microlearning centers around understanding the difference between CDM and CDM messages.
25 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
26
27 * The complete CDM consists of the collection of entities that are used or going to be used in the various CDM messages

31 == 3. Difference between CDM and CDM messages ==
32
33 Simply put the difference between the CDM and the CDM messages is as follows:
34
35 * The CDM holds all entities and attributes that are relevant within the context of your complete integration landscape.
36 * 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.
37
38 So that means that when you navigate to Design -> CDM you will see everything

41
42 Afterward when you zoom in on one of the available message types to create or view your CDM message the overview
43 changes to show the structure of the message and to show which parts of the CDM are used for the CDM message.

49 == 4. Assignment ==
50
51 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.
52 This assignment can be completed with the help of your (Academy) project you have created/used in the previous assignment.
53
54 == 5. Key takeaways ==
55
56 * The CDM holds all entities and attributes that are relevant within the context of your complete integration landscape.
57 * 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.
