There are reasons to use or not to use relational databases. Explore the typical use cases in this video.
- [Instructor] We covered the pros and cons…of document databases versus relational databases…already when we talked about document databases before,…but let me emphasize that again real quick.…You want to use relational databases…when there are multiple different entities…that are in some way related,…and when the database needs to stay in a consistent state…and when the database should also enforce this consistency,…no matter from which application is accessing it.…
In our example now, we will use MySQL to store our orders.…For that we will first transition the basket…that is currently stored in Redis…into an order and we will store…all items inside this order in a table OrderItem.…Then we will delete the contents of the basket…and everything going on here…should run in one transaction.…This means it's either everything or nothing,…and that's a very nice use case…for a relational database, like MySQL.…
