Answer 1

Hi friend,

In this method, the system presents a blank record and lets you specify the fields and values that define the query. Query language: Many database systems require you to make requests for information in the form of a stylised query that must be written in a special query language.

HOPE THIS HELPS:-))

Answer 2

Query language is a computer programming language. A query is a request for information from a database. A database query can be either a select query or an action query. A select query is a data retrieval query, while an action query asks for additional operations on the data, such as insertion, updating or deletion.The uses of databases are manifold. They provide a means of retrieving records or parts of records and performing various calculations before displaying the results.
