Query

A query is a request for data or information from a database, typically structured to extract specific data from large volumes of stored information. Queries are essential in database management systems (DBMS) as they enable users to retrieve, manipulate, and analyze data efficiently. They can be simple, such as retrieving a list of names from a database, or complex, involving multiple conditions and relationships between data sets. Queries are written in query languages like SQL (Structured Query Language), which provide commands for performing various operations on the data. Understanding how to craft effective queries is crucial for data analysis, reporting, and decision-making processes within any data-driven organization.
