SQL database is widely used on the Internet. Whether it is a simple website, online application, cloud, or online service, all use SQL databases to manage their data. Apart from the online use, SQL database also has applications in software and other offline tools as well.
A database has various groups and entities with primary, private, and/foreign keys. These keys are essential for the communication between the datasets/groups. With all the datasets, entities, and keys, it is hard to keep track of everything so making a database diagram is the most ideal solution.
A SQL database diagram is a structure of its datasets, that represents how data is organized and how the relations among them are associated. Now, making a database diagram can be easy and hard depending on how you are making it. There are many online tools out there where you can make database diagram either by drawing each dataset and relation or by creating separate group for each dataset and then defining relations among them. This doesn’t sound easy and fast.
