AUT-QPM: The New Framework to Query Evaluation for Data Warehouse Creation %K Data warehousedata warehouse designmethodologyquerysimulatorsoftware engineering %X The main reason of data warehouse systems failure is lack of justification proof. Analysis is an important task for decision about data warehouse creation. In this paper, we present the framework to justify data warehouse based on the input query types. We classify query types and execute them on the databases and data warehouses with different sizes. The query response time and the number of I/O are evaluation parameters. In the experiments, different types of queries have been processed on databases and data warehouses and the results based on time and memory have been compared. These results are presented below: • For answering multidimensional queries and aggregated queries data warehouse systems will be required, • For answering nested queries and join queries, data warehouse system will be useful, • Database systems will be proper for answering simple queries and computational queries. In this work, the tools which can process the above ideas have been produced. The software will take user query and evaluate its process to decide having or not having data warehouses. %U http://rimag.ir/fa/Article/27894
