Many people who know so much about SQL and even have created many projects based on SQL and they do not know what is SQL engine or how actually SQL database works. Without knowing How SQL works we can still create and access database using any SQL program. We have many types of SQL engines and they all have different architecture, but used to perform the same objective which includes CRUD operations on the database and many other features. The objective of SQL engine is to create, read, update and delete (CRUD) data from a database.
