FREM is an acronym that stands for "Functional Requirements and Entity Model." It is a concept commonly used in software engineering and systems analysis to design and document the functional requirements and data entities of a system.
In software development, functional requirements refer to the specific behaviors, operations, and capabilities that a system must have in order to fulfill the users' needs or organizational goals. These requirements are typically outlined in a functional requirements document (FRD), which serves as a blueprint for the software design and development process.
On the other hand, the entity model in the context of a FREM represents the high-level structure and relationships of the entities or objects within a system. An entity is a person, place, object, concept, or event that has relevance in the system being designed. The entity model shows the different entities, along with their attributes (properties or characteristics), and the associations or relationships between them.
By combining functional requirements and entity modeling, a FREM provides a comprehensive overview and understanding of how the system will function and what data entities will be involved. This aids in the analysis, design, development, and maintenance of the software system, ensuring that it meets the desired objectives and satisfies the users' needs.
