What are Query Rewriting Techniques in DBMS?
Rewriting techniques include a package of approaches that allow changing complicated queries into their logical equivalents, which provide the same results but are more effective. They exploit the features of the query optimizer that compile only those plans that have minimal resource use, a high-performance rate, etc. Query reformulation stands for transforming queries so that they extract content and process the data in the most optimized way, which does not modify the results as compared with the original query.
What is Query Rewriting Techniques in DBMS
In the world of DBMS, efficiency and optimization define everything; as a result, it is the most important. The art of optimization is used to enhance database queries. It is Query rewriting. The process of query rewriting pertains to the conversion of the given form query into an equivalent form that enables the search to be executed faster with the use of many optimization strategies.
