Query language is a powerful tool that allows users to select specific database records. This language is capable of performing complex search operations and filtering data based on specific criteria.
One of the most well-known query languages is SQL, which stands for Structured Query Language. SQL provides users with a prepared query menu and the ability to query by example through typed commands, making it a highly effective way to retrieve the desired database records. Additionally, QBE or Query By Example is another popular form of query language.
For those who need to query non-DBMS files, there is a stand-alone program available as well. However, most database management systems (DBMSs) include their own query language.
