Publication number: 20170206199Abstract: According to embodiments, a derived cache that is derived from a first instance of particular data is used to speed up queries and other operations over a second instance of the particular data. Traditionally, a DBMS generates and uses derived cache data only for the database data from which the derived data was derived. However, according to embodiments, derived cache data associated with a first instance of database data is relocated to the location of a second, newly created, instance of the database data. Since the derived cache data is derived from an identical copy of the database data, the cache data derived for the first instance can successfully be used to speed up applications running over the second instance of the database data.Type: ApplicationFiled: January 19, 2017Publication date: July 20, 2017Inventors: Kothanda Umamageswaran, Krishnan Meiyyappan, Adrian Tsz Him Ng, Vijay Sridharan, Wei Zhang, Ke Hu, Xin Zeng

Patent number: 9284692Abstract: The present invention relates to a switch monitoring method and a switch monitoring system, a railway line management method and a railway line management system. Electric signal of a switch motor during pulling of the switch can effectively reflect status of the switch, when the switch is in a stable state, electric signal of its motor is very steady during pulling of the switch; however, when the switch is in an unstable state, there will be different degrees of fluctuation in electric signal of its motor during pulling of the switch. Thus, the invention may be used to identify state of a switch by monitoring electric signal of a switch motor, and further take different measures based on different states of the switch. With these measures, accidents due to switch failure may be effectively reduced, and train delay time may also be reduced through proper line management.Type: GrantFiled: October 28, 2015Date of Patent: March 15, 2016Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Ning Duan, Ke Hu, Li Li, Wen Ting Mo, Wei Sun, Xi Sun, Feng Juan Wang
