A database diagram is an illustration or chart that shows the relationships between data elements in a specific database. It visually highlights the structure of a particular database, allowing someone to quickly understand how it works. An example of a specific type of database diagram is an API gateway diagram for Redis. This diagram would show how incoming requests are routed to and managed by Redis, as well as what data is used and where it is stored.
