Selecting views to materialize is one of the most important decisions in designing a data warehouse. Decision support systems usually use complex queries in large databases. Because response time should be short, therefore query optimization is very important. In this paper, we present four advances...
In this paper, we will enlist the process of SQL query optimization based on Heuristic approach. It is often found in the database industry that a lot of time is consumed in executing inefficient SQL queries. The problem here is that although the DBA knows that the queries red are ...
Query Optimization Over Web Services Using A Mixed Approach The main aftermath of our research is ensued in an algorithm which uses cost-based as well as heuristic based approach for query optimization. Query plan... D Mukhopadhyay,D Chandarana,R Dave,... - Springer Berlin Heidelberg 被引量:...
Now a day, it is very common to see that complex queriesare being vastly used in the real time database applications.These complex queries often have a lot of common subexpressions,either within a single query or across multiplesuch queries run as a batch. Multi-query optimization aimsat ...
