Logical Design
Logical design is a phase in system development that focuses on defining the structure and behavior of a system without considering physical implementation details. It involves creating abstract models, such as entity-relationship diagrams or UML diagrams, to represent data, processes, and interactions. This step bridges requirements analysis and physical design, ensuring the system meets functional needs before technical constraints are applied.
Developers should learn logical design to create scalable, maintainable systems by clearly separating business logic from implementation details. It is crucial in database design, software architecture, and system analysis, helping prevent errors early in development. Use cases include designing relational databases, planning software modules, and documenting system workflows for teams.
