Final answer:
The representation of content, relationships, and constraints of data that supports system requirements is known as a Data model, which is answer d to the original question.
Step-by-step explanation:
The representation of the content, relationships, and constraints of the data needed to support the system requirements is known as the Data model. A data model is an abstract representation that helps understand the structure and the rules about how data can be stored, connected, accessed, and updated within a given system. This includes graphical representations, descriptions of data structures, and the rules governing how data is validated and handled.
Developing a data model is one of the major steps in moving from a conceptual design to a detailed architectural design of a system. It involves identifying the criteria and constraints of the design to determine which design best solves the design problem. Criteria are standards or attributes that can be measured, such as weight and size, while constraints are the limitations or conditions that must be satisfied by the design.
Therefore, the correct answer to the original question is d) Data model.
