What is the purpose of the COLLATE keyword when creating a new database in MySQL?

The COLLATE keyword in MySQL defines the collation (sorting and comparison rules) to be used for the character set of the database. Collation determines how string values are sorted and compared in queries, including operations like ordering, grouping, and comparing values.

When creating a new database in MySQL, specifying the COLLATE keyword allows you to set a default collation for all the character columns in the tables within that database. It ensures that string comparisons and sorting operations are performed in a predictable and consistent manner based on the specified collation rules.
