Glossary: Data ModelGlossary

A data model is a representation of data elements describing how that data is structured, related, and used. It provides a framework for defining the data elements and their relationships, which are crucial for designing databases, data warehouses, and other data systems.

The key components of a data model are:

• Entities: Representations of objects or concepts that are important to an organization or process, such as a customer, business transaction, email or chat message, or generative AI prompt.
• Attributes: Properties or characteristics of entities. For example, a customer entity would have properties like a name, email address, and phone number.
• Relationships: These describe how entities are related or connected to each other, or how they interact with each other. Relationships can be one-to-one, one-to-many, or many-to-many. For example, a customer can place multiple orders, which would be represented by a one-to-many relationship between the corresponding customer entity and many order entities.
• Keys: Unique identifiers for entities. There are primary keys, which unique identify an entity, and foreign keys, which link entities of different types.
