Database querying is the process of requesting specific information from a database. It involves using a structured language, often SQL (Structured Query Language), to communicate with the database. Users can retrieve, update, or delete data by writing queries that specify the desired information and conditions. Queries can be simple, asking for all records in a table, or complex, involving multiple tables and conditions. The results are typically returned in a structured format, making it easier for users to analyze and utilize the data for various applications, such as reporting or decision-making.
