About this document

SQL: Key Tools for Data Manipulation by AASEEN ALAM is a document available to read on EtoBox.

SQL is a standard language for storing, manipulating and retrieving data in databases. It allows users to execute queries to retrieve data, as well as insert, update and delete records. Common SQL statements include SELECT to retrieve data, INSERT to add new records, UPDATE to modify existing records, and DELETE to remove records. The execution plan produced when a query is run shows the steps and path the database will take to access and return the requested data, and can help optimize query performance.
