What is Query Manager?

Query Manager is a broad term referring to a system or component responsible for processing and optimizing database queries. It often sits between the user or application and the underlying database, receiving queries, analyzing them (e.g., for syntax, security, and potential performance issues), rewriting them if necessary, and then dispatching them to the database. A Query Manager may also manage query caching, connection pooling, and resource allocation to improve overall database performance and efficiency. It is commonly used in database management systems (DBMS), data warehouses, and applications that heavily rely on database interactions.
