30 30  A data model is a visual representation of how a system has structured its data. With the help of a data model, you can show the relationships between entities and define the attributes on the entity level. See below for a small example of a data model.

34 34  As you can see above, we have several entities (i.e., Order, Invoice) related to each other in a certain way. Furthermore, we see that our entities are defined through the help of attributes. So, for example, our Order entity holds an ID, Date, and Description attribute. The data model also tells us the data types of the entity's attributes. Therefore the picture above tells us that the ID is represented as an integer, the Date is a DateTime, and the Description is defined as a String (Text).

48 48  In the messaging pattern of eMagiz, we use a Canonical Data model (CDM). Canonical data models are a type of data model that aims to present data entities and relationships in the simplest possible form to integrate processes across various systems and databases. More often than not, the data exchanged across multiple systems rely on different languages, syntax, and protocols.
