Welcome again! In this part of our course, you will learn about various data types. Different databases have their own data types, but there are quite a lot of basic types that you will come across in every database. We'll present these types in this part of our course.
You may remember some data types that we used in the previous part. Let's review what they are now.
A data type specifies what kind of information can be stored in a given column. There are different data types because the database needs to know how much space it should allocate for information in each column. This way, it can also sort the data accordingly.
Now that we remember what data types are, we can discuss some of them in detail. Are you ready? Click the button and let's get started!
