This structure was chosen due to its familiarity with funders, investigators, readers, and reviewers. The Logical Model. The logical model is the version of the model that represents all of the logical business requirements of an organization. There are three levels of logical models that are used to capture these requirements: The Entity Relationship Diagram - A high-level data model that includes all major entities and relationships. The conceptual and logical data models describe how information is organized in a system regardless of the database used. The logical model specifies entities, attributes, and relationships between entities. It abstracts away from actual DBMS used in the implementation of the system. Physical Data Model. The physical data …The Logframes and Logical Framework Approach, is an analytical process that stands for project or programme planning, monitoring, and evaluation. The associated ‘logframe matrix’ serves as a discrete planning and monitoring tool for projects and programmes. Logframe matrices are developed during project/programme design and …Vertabelo allows us to use inheritance in database logical data models to represent the idea of a child entity being derived from a parent entity, as we can see in the following image. In the above logical model, we used inheritance to represent the idea that “any car is a vehicle” and also any “bike is a vehicle”.A logic model is a diagram that visually represents the logical relationships among the resources, activities, outputs, audiences, and outcomes of a program.
