Database Design and Entity-Relationship Modeling flowcharts

Database design and entity-relationship modeling flowcharts

These flowcharts show database designs through different examples. ER Model connects suppliers, products, orders, employees and sales. Hospital Relationship Entity Diagram includes patient and sector details, with fields marked as primary and foreign keys.

Start with ER Diagram - Updated if you want to follow a diagram centred on members and toys. Look at the entities, then trace the links between them and the attributes attached to each. The toy details include location, price and purchase date.

Revise with the diagrams

Compare the labels and connections in two flowcharts, then try describing each design without looking at it. Return to the diagrams to check what you missed. The flowchart about team, player and coach relationships gives you another set of examples to examine.

When you want to check your understanding, switch to a quiz on the unit page. Use flashcards there to revisit terms. Choose a diagram and trace its connections.
