3) Data Model and Flow

Describe the data entities and how the data flows between components

The data model portion of a frontend system design is a crucial component in ensuring that the system functions as intended. It defines the structure of the data that will be used within the system and how it will be organized and accessed.

The data model defines the various data entities that will be used within the system. These entities can be thought of as the different types of data that the system will be handling, such as user information, product information, and transaction data. Each entity will have a specific set of fields that contain the relevant data for that entity. For example, a user entity may have fields for name, email, and password.

Once the entities and fields have been defined, the data model will specify which component(s) the data belongs to. This is important for ensuring that the data is properly organized and accessible within the system. For example, user data may belong to a component that handles user authentication and authorization, while product data may belong to a component that handles displaying and managing product information.

Overall, the data model portion of a frontend system design serves as a blueprint for how data will be structured and accessed within the system. It is essential for ensuring that data is organized in a logical and consistent manner, and that it can be easily accessed and used by the various components of the system.
