The plurality of query types are chosen such that any possible query can be classified as being of one query type. The plurality of queries is compatible with the particular interface. The method and system include running the query spectrum on the database engine and determining a time taken to run each of the plurality of queries on the database engine. In another aspect, the method and system are for characterizing the application. In this aspect, the method and system include characterizing the database engine using a query spectrum including a first plurality of queries compatible with the particular interface. The first plurality of queries has a plurality of query types. The method and system further include providing a second plurality of queries characteristic of the application. The second plurality of queries have a portion of the plurality of query types and are compatible with the particular interface. The method and system further include calculating a run time taken to run the second plurality of queries on a portion of the plurality of database engines based on the portion of the plurality of query types and characterization of the plurality of database engines.
