Declarative Schema in Magento 2.3 | StageBit

When I was creating a module I notice a new thing in Magento 2.3. Magento 2.3 core modules used a declarative schema approach instead of a setup upgrade script. This is a new recommended approach in Magento 2.3 and above.

Declarative schema reduces the unnecessary work of writing upgrade scripts for just a little change in the database. For example, If you want to rename a column, you need not write a setup upgrade schema script in the next version of that module. You can change the schema in db_schema.xml and run the setup upgrade command.

This allows the developer to declare the final state of the database. As a result, it will reduce redundant operations. It reduces the process of writing code in the next version. Because of this approach, you can delete data when you uninstall the module.
