It serves as a vital tool for analyzing how various data entities interact with one another based on these four core operations.

In a CRUD matrix, each row typically represents a different entity or piece of data, while each column represents one of the CRUD operations. This gives stakeholders a clear overview of which operations are permitted for each data entity, facilitating a better understanding of system capabilities and data management requirements.

This visual representation helps in requirement analysis by clearly indicating which data needs to be created, retrieved, modified, or removed, thus ensuring that the development aligns with business needs and system design requirements. By using a CRUD matrix, business analysts can effectively communicate the necessary functionality of a system regarding data handling to the project team and stakeholders.

The context of the other options highlights their differences from the main function of the CRUD matrix. For instance, the mapping of user roles (the first option) focuses on showing how different users interact with a system, rather than detailing specific data operations. Data relationships (the second option) concern how different data entities are connected but do not specify the
