A method of optimizing ranking queries in analytic applications. The method involves dividing a ranking query constructed by a user into multiple sub-commands. These sub-commands are based on the relationship between the foreign key and ranking attributes of a table of data and are run as a batch of commands. As usable data is extracted from each sub-command, it is stored and the foreign key is used as a filter for the next query in the batch. This eliminates accessing irrelevant data and facilitates the query operation. The extracted data is joined as the last step of the process in order to minimize the number of join operations performed by the query while the batch is being executed, thereby facilitating the query process.
