The invention provides a query processing method, which relates to the field of cloud computing and comprises the following steps that: a service node analyzes a query request and generates a corresponding logic execution plan; the service node judges whether the logic execution plan belongs to OLAP scale query service or OLT scale query service; when it is judged that the logic execution plan belongs to OLAP scale query service, the service node divides the logic execution plan into a plurality of logic execution sub-plans; the coordination node generates a first physical execution plan corresponding to the logic execution plan and feeds back the first physical execution plan to the service node, and the first physical execution plan records node information of processing nodes corresponding to the logic execution sub-plans; the service node distributes each logic execution sub-plan to the corresponding processing node according to the first physical execution plan; the processing node processes the corresponding logic execution sub-plan to obtain a query sub-result, and reports the processing sub-result layer by layer; and the service node gathers the received processing sub-results, generates a final query result and feeds the final query result back to the user.

The invention relates to the field of mobile communication, and provides a weather information display method. The weather information display method comprises the steps of determining weather information to be displayed according to city attribution information and city location information of a SIM card, and displaying the weather information correspondingly. The invention further provides a mobile terminal which is used for implementing the method. The embodiment of the invention not only presents real-time weather information of located cities to users, but also presents weather information of city attribution to the users, thereby enabling the users to acquire required weather information timely and accurately no matter where the users are, meeting different query requirements for weather conditions of different users, saving operating steps of the users, providing more considerate weather services for the users, and effectively improving the user experience.

The invention discloses an intelligent ship lock operation and maintenance system based on BIM, which belongs to the technical field of ship lock management and control. The system includes a BIM management subsystem, an equipment management subsystem, a fault detection subsystem, an operation and maintenance management subsystem, a platform management subsystem and a database. The technical problem on how to realize centralized management and control of the operation states of equipment in a ship lock control system is solved by taking standardized BIM as the model basis. By taking standardized BIM as the model basis, the requirement of ship locks for the integration of storage and query of building, maintenance and management data can be satisfied. The random forest of the invention, asa novel artificial intelligence method, has good classification performance and robustness. As the advantage of the invention, the fault diagnosis technology combines expert knowledge with the artificial intelligence method organically.

The invention provides a method for conducting term matching on the basis of a double-array lexicographic tree. The method is characterized by comprising the steps of index creating, wherein a location of the double-array lexicographic tree is generated, an ID of a secondary index of a memory cache system is calculated, and an index is created for items; term querying and matching through the index, wherein the location of the double-array lexicographic tree is generated, word segmentation is conducted, and term matching is conducted on the basis of the index. Not only can multiple querying requirements of term matching be met, but also the overall matching performance is improved.

The invention discloses a method and device for achieving switching of tab pages and a browser client side. The method comprises the steps that keyword information input into a browser input field is acquired; whether the keyword information meets a preset tab page search format or not is judged; if yes, information of all open tab pages in a browser at present is acquired, matching between the keyword information and the information of all the open table pages at present is conducted to obtain a matched tab page; access to the matched tab page through switching is provided in the browser input field, and therefore the matched tab page can be switched to through the access. According to the technical scheme, a user can obtain the switching access of the tab page matched with input keywords in the input field only by inputting the keyword information into the browser input field, and therefore switching of the tab pages can be conveniently conducted, the inquiry requirements of the user are met, the inquiry habit of the user is met, and great convenience is provided for the user.

The invention relates to an object-oriented kernel layer database, and the database is characterized in that when the database runs, all data is stored in a memory allocated by a kernel layer; the database is object-oriented and is uniformly described by an architecture definition; an access unit of the database is an object and an object attribute, and the database comprises an interface layer, wherein the interface layer is is used for receiving and processing an access request and a structured query request of an object; a logic layer which is used for realizing object access, wherein the operation on the object is based on an object identifier, and the object identifier can be calculated and converted into an object pointer of a programming language; a physical layer which is used for realizing data access of objects and object attributes, wherein the physical layer is also used for storing a global index table, the global index table is used for establishing a path index of a specific type of object, and the physical layer is also used for realizing persistent storage of the object data and the object attribute data. Therefore, storage and query requirements on complex objects in a kernel scene are met, and the access efficiency is improved.

The invention discloses a quick data query method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining query information, and analyzing the query information to obtain a query keyword; judging whether the query keyword is in a pre-constructed hot word index or not; when the query keyword is in the hot word index, obtaining target data from a cache database; when the query keyword is not in the hot word index, obtaining an associated keyword according to the query keyword and a preset keyword association table, obtaining initial return data from a dynamic database according to the associated keyword, and optimizing the initial return data to obtain target data; and obtaining a query result according to the target data. According to the method, the parallel processing and query efficiency of the big data can be improved, the real-time query of the business data is realized, the operation efficiency of an enterprise is improved, the operation and maintenance cost of the enterprise is reduced, a business query result is more comprehensively and accurately provided, and the experience feeling of a user is improved.
