12 12  This microlearning centers around understanding the concept data modeling in design.

14 -== 3. CDM, CDM & system message, message mapping ==
15 -By following the steps below, you should gain a better understanding of the differences between CDM, CDM messages, and system messages.
14 +== 3. Please complete the following steps ==
16 16  
17 -* Creating a CDM
18 - Please import the file Order.xsd in your CDM.
19 -* Creating a CDM message ==
20 - Now, go to your CDM message and select Order as root entity. Add all other entities and attributes from Order.xsd, which were imported into the CDM, to your CDM message definition.
21 21  
22 -== 3.3 Creating a system message ==
23 -In one of your System messages, import the file TransportOrder.xsd. Select CreateOrder as root entity and add all other entities and attributes to your system definition.
17 +=== 3.1 Creating entities and attributes in your CDM ===
24 24  
25 -== 3.4 Complete message mapping ==
19 +Please add the following entities and attributes to your CDM:
20 +
21 +* Person, with attributes ID, Name, and Email.
22 +* PlatformCourse, with attributes ID and Name.
23 +
24 +One person has access to many platform courses. It should look like the following:
26 26  
27 -Now that you have completed these steps, go to Message mapping and complete the mapping.
28 28  
29 -The solutions to these exercises can be found [[here>>doc:Main.eMagiz Academy.Use Cases.Data modeling in Design.Exercises.Solutions.WebHome||target="blank"]].

31 -== 4. Key takeaways ==
32 32  
33 -* The CDM holds all entities and attributes that are relevant within the context of your complete integration landscape.
34 -* The CDM message is tailor-made for a specific piece of data and only holds the entities and attributes relevant for that piece of data.
35 -* A system message is specific to a system.
29 +== 4. Assignment ==
36 36  
31 +Navigate to Design and open the message definition option of at least one integration within your project.
32 +This assignment can be completed within the (Academy) project that you have created/used in the previous assignment.

40 -If you are interested in this topic and want more information on it please read the help text provided by eMagiz.
36 +* A message definition is a visual representation of how the elements are related to each other, whether they are mandatory and the data types they have that can be used in the message mapping
37 +* Some message definitions are specific to a system. Others are generic across systems
