摘要： The query method and device suitable for an On-Line Analytical Processing (OLAP) query engine includes a client agent module, a query pattern matching module, a query distributed execution module, and a pre-aggregation module. The query pattern matching module is configured to obtain an MDX query request received by an OLAP query engine and process the MDX query request to generate at least one set of aggregation query sets. The one set of aggregation query sets includes a plurality of aggregation query requests. The query distributed execution module is configured to perform concurrent processing on the plurality of aggregation query requests. The aggregation query requests are arranged corresponding to the aggregation query results. An efficient OLAP query execution engine can deal with complex OLAP queries of various reporting system. Therefore, the execution efficiency of MDX query can be significantly enhanced, and analysis requests of the reporting systems are rapidly responded.

摘要： The cloud cost-based resource deployment system and method includes a dynamic deployment strategy module, a resource life cycle management module, and an automatic resource operation and maintenance module. The dynamic deployment strategy module automatically analyzes and combines resource deployment schemes. The resource life cycle management module docks with Application Program Interface (API) of various public clouds, and internally provides standardized and unified interfaces. The automatic resource operation and maintenance module modifies the resources in real time through the public cloud API and a manner of remotely connecting to infrastructure resources. Unified and efficient management on a plurality of public clouds is performed. For cloud resources, deployment strategy can be automatically adjusted for different operation systems, so that the public clouds can be efficiently used with a low cost.

摘要： The Online Analytical Processing (OLAP) precomputation engine optimization method based on an object storage, and application, and provides three optimization directions: reduction of an object renaming operation, data consistency check, and inversion of a logical path of an index file. A mapping relationship of a file before and after renaming is matched through a file mapping table added to a metadata layer, and a renaming operation on a bottom layer of a file system is reduced. Logical path inversion of a partition directory hierarchical structure of the file is corresponded to a prefix of the file in the object storage, and the object storage is rapidly queried and read. Logical verification is added to a read operation, a deletion operation, and a write operation, and the data consistency is checked.
