摘要： The present invention provides a recovery method using extendible hashing-based cluster logs in a shared-nothing spatial database cluster, which eliminates the duplication of cluster logs required for cluster recovery in a shared-nothing database cluster, so that recovery time is decreased, thus allowing the shared-nothing spatial database cluster system to continuously provide stable service. In the recovery method, if a failure occurs in a predetermined node, a second node in a group, including the node, records cluster logs in main memory on the basis of extendible hashing. If the node that has failed recovers itself using a local log, the second node in the group transmits cluster logs in packets to a recovery node that is the failed node. If the recovery node reflects the received cluster logs and maintains consistency with other nodes in the group, the recovery node resumes normal service.

摘要： A vector-based system maximizes the performance of a server of a clustering Web geographic information system by realizing efficient load balancing using a load balancing processor, thus improving the system's reliability and stability. A control method of the system minimizes a user response time by using a progressive transmission technique when transmitting vector data.

摘要： The present invention provides a novel sulfonamide derivative of general formula (I) useful as an inhibitor of matrix metalloproteinase (MMP), its isomers, pharmaceutically acceptable salts thereof and a process for preparing the same. Since the sulfonamide derivatives of the present invention selectively inhibit MMP activity in vitro, the MMP inhibitors comprising the sulfonamide derivatives as an effective ingredient can be practically applied for the prevention and treatment of all sorts of diseases caused by overexpression and overactivation of MMP.
