MySQL: Check Database and Table Size
This process will work in all cases, whether you are accessing your database through the command line or using any GUI tool (like MySQL Workbench or HeidiSQL). Because the size-related information is already saved in a specific MySQL table. Check the table named “TABLES” from the database “information_schema”, you will find all the information related to the sizes of the tables.

Singleton pattern is used to ensure that only one instance of a class is created in any case, and whenever you want to get an instance of that class, then the same object instance is returned.
