Process of SQL

When you are executing an SQL command for any RDBMS, the system determines the

best way to carry out your request and SQL engine figures how to interpret the task.

There are various components included in this process.

These components are –

 Query Dispatcher

 Optimization Engines

 Classic Query Engine

 SQL Query Engine, etc.

A classic query engine handles all the non-SQL queries, but a SQL query engine won't

handle logical files.
