How to Design a Database

If you’ve got an idea or requirements to create a database, and don’t know how to design it, then this is the video for you.

You can take an idea or some requirements for an application and create a database design.

In this video, I’ll explain step-by-step how you can do this, using an example. We start with a written description of what we want to do, and end up with a database design with a few tables, columns, and primary and foreign keys added.

Timestamps:

Videos like this are way more useful than the other bog standard stuff that litters the web - rather than over-explaining 'how to query a, b, c, d and e', your videos cover the more important fundamentals like how to design relational databases properly. The querying can just be googled as you develop, but leaning how to design a database cannot be googled so easily. Thank you

your video was absolutely helpful compared to class lectures about database management, do you have anything on how to design (even with pen and paper) other kind of relationship between tables? Thanks a lot!

This was helpful, although I have a massive database I’m planning. Maybe I will need to break it down into small chunks as I go?

Hi there, thanks for this! I was wondering how we can do with multiple patients at the same time, perhaps create a separate table of patients and how will we identify other patients from that table list?
