Abstract: A computing device can receive a query in a first query language that identifies a set of data to be processed and determine that at least a portion of the set of data resides in an external data system that uses a different query language. The query system can translate the query in the first query language in to a second query language for the external data system. To retrieve results of the translated query, the computing device may determine a quantity of results of generated by the translated query and generate one or more results readers to read the results in parallel. The computing device may further process the results and provide them to a user.

Abstract: Disclosed is an identification method for a Wideband Code Division Multiple Access (WCDMA) network cell soft switching band. The method includes that: a data collection server performs positioning calculation of a mobile station according to Round Trip Time (RTT) data, collected by a Radio Network Controller (RNC), of each of cells in an active set, performs grid statistics according to a positioning calculation result, and stores a statistical result; and a client calculates and displays a soft switching band of a cell in an active set to be queried according to the statistical result corresponding to the cell. Also disclosed are a system corresponding to the method, a data collection server and a storage medium.
