ultimate99 Posted December 17, 2017 Share Posted December 17, 2017 I'm planning to create a small database to store and manipulate patient data in SQL, but I figured that I need to know about Entity Relationships. Any pointers to where I can read it about and start my little project? Link to comment Share on other sites More sharing options...
0 Seahorsepip Veteran Posted December 17, 2017 Veteran Share Posted December 17, 2017 Some background info and details about (E)ER diagrams: https://www.lucidchart.com/pages/er-diagrams Chen notation style is most commonly used and my recommendation due to it's simplicity. Start by making a list of entities, then draw those as squares and map their relations as diamonds. Finally add the properties of those entities as ovals. If you want any feedback on your work feel free to post it here or send me a PM. Link to comment Share on other sites More sharing options...
