A data model is a collection of conceptual tools for describing all of these: Consistency Constraints, Data Schema, and Data.

Here's a step-by-step breakdown:

1. Consistency Constraints: These are rules that are applied to maintain the correct relationships between the data. For example, in a school database, a student cannot be enrolled in a course that does not exist.

2. Data Schema: This is the structure of the data in a database. It defines how data is organized and how the relations among them are associated. It involves the description of various entities, attributes, and relations.

3. Data: This is the actual information stored in a database. It can be any form of information that can be stored and retrieved, such as text, numbers, images, etc.

So, a data model encompasses all these aspects to provide a comprehensive view of data storage, manipulation, and integrity.
