SQL Data Types

SQL Server and other relational database management systems use data types to hold data in specific columns.

Different data types are available, depending on the data that we want to store. For instance, we may want to store currency values, a product number, and a product description. There are certain data types that we must use to store that information. Most data types between each RDBMS (keynote: Relational database management systems) are relatively the same, though their names differ slightly, like SQL Server and MySQL. There are many data types that we use more than others. There are some common data types that we might use in the future.
