Performance and Query Optimization

What is Query and Performance Optimization?

Query optimization is a function of many relational database management system. The query optimizer attempts to determine the most efficient way to execute a given query by considering the possible query plans.

Generally, the query optimizer cannot be accessed directly by users: once queries are submitted to database server, and parsed by the parser, they are then passed to the query optimizer where optimization occurs. However, some database engines allow guiding the query optimizer with hints.

Query optimization requires the in depth knowledge of the database engine. Adlab database certified consultants review, identify and optimize the bad written queries on the system. The consultants monitor and tune queries on proactive basis, which helps in achieving the optimal system performance.
