ERDPlus tool

ERDPlus is a free online tool used to create diagrams that help organize and visualize how data relates within a system, like a database. It allows users to design entity-relationship diagrams (ERDs), which show different entities (e.g., people, products) and the relationships between them. This assists in planning and understanding data structure before building software or databases. The tool provides an intuitive interface for drawing and managing these diagrams, making it easier for professionals to communicate ideas and ensure data models are well-structured.
