1. Reproduction

The first step in creating good diagrams is simply to copy an existing one faithfully. Use draw.io to reproduce the diagram below.

2. Translation

The links below lead to ER diagrams which are not in UML format. Use draw.io to produce a UML version of each one.

• Bus stops
• Accidents at work
• The games store
• Student lab teams

3. Problem solving

The diagrams linked in this section all have something wrong with them. Write down as many problems as you can identify - some diagrams may have several issues. When you have done that, use draw.io to create a correct version of each one.

• Banks and branches
• Car hire
• Library books (download and open with draw.io)
