How to fill out data model description

How to fill out data model description:

1. Understand the purpose: Before you start filling out the data model description, it's important to understand the purpose of the data model. This will help you articulate the right information and ensure that the description aligns with the intended use of the data model.
2. Identify the entities: Begin by identifying the entities that the data model describes. Entities can be people, objects, concepts, or events that are relevant to the specific domain or problem you are addressing with the data model.
3. Define attributes: Once you have identified the entities, describe the attributes associated with each entity. Attributes are the characteristics, properties, or qualities that define the entities. For example, if the entity is "customer," attributes could include name, address, email, etc.

5. Specify cardinality and constraints: Cardinality refers to the number of instances of one entity that can be associated with another entity. Determine the cardinality of each relationship in the data model. Additionally, specify any constraints or rules that govern the relationships or attributes. This could include things like mandatory or optional attributes, unique values, etc.
