The ERD Exerciser is a Java application designed to help students practice their ability to create entity-relation diagrams (ERDs). It contains a variety of questions which present scenarios for the user to draw an ERD for. After the ERD is drawn, the user can ask the tool to grade their diagram. The tool will compare the user's diagram to a known solution and assign a mark. The user will then receive feedback in diagrammatic form on their work. This feedback can be used to improve the user's ERD.
