Want to know how to create and diagram a database design one to many relationship? Watch this video to find out.
In database design, one to many relationships are the most common type of relationship between tables. They represent records in one table being related to many records in another table.
If you’re just getting started with designing your database, you may not know how they fit into your design or how to determine which relationships are on to many.
In this video, you’ll learn all about them and how to add them to your design.
You’ll learn:
- What a one to many relationship is in database design
- How to work out what objects or tables you are actually working with
- How to determine which way the database design one to many relationship actually goes
- How to create a standard diagram that shows the one to many relationship between the two tables
The diagram you’ll start creating is called an Entity Relationship Diagram, or ERD for short. It’s a standard diagram used to define a database. There are many software tools out there for doing this, but it’s just as easy to do on pen and paper in this video.
The video breaks this process down into 7 steps, and includes several examples of this process. If you follow these steps with the database you’re trying to design, you’ll be able to define your relationships in no time!
