The invention discloses a method for batch checking, downloading and utilization of invoices based on a national network invoice platform, and belongs to invoice batch checking, downloading and utilization methods. The technical problem that a bill-to party and a drawee party of the invoices can not achieve invoice batch checking and downloading is solved. According to the technical scheme, by means of the method for batch checking, downloading and utilization of the invoices based on the national network invoice platform, invoice batch checking, invoice batch downloading and invoice information utilization are achieved based on the national network invoice platform; the national platform invoice platform is a cloud server, a national network invoice database is arranged to store network invoice data, the national network invoice platform achieves gathering and distributing of network invoice data in the network invoice databases of all provinces, invoices issued by bill-to parties in a province-crossing mode in all the provinces are differentiated according to the registration information of taxpayers, and the invoices are pushed to the network invoice databases of the province where the drawee parties are placed.

The invention provides a data storage method and device. The method comprises the steps: performing modulus operation of a preset numeric value on identification information of to-be-stored data, wherein the identification information is a numeric value, and the preset numeric value is the number of storage nodes; and storing the to-be-stored data into storage nodes corresponding to the result of the modulus operation. The data storage method and device overcomes the defect of slowing down data query caused by the continuous increasing of data volume in the prior art; the data is stored in a plurality of the storage nodes by means of the modulus operation; therefore, the to-be-queried data is positioned on one storage node by means of the modulus operation during data query, and the query scope is reduced, the data is further inquired in the storage node and the query efficiency is improved.

The invention provides abstract-type network search engine system and searching method and the application thereof. The system mainly comprises a user interface, a page catching module, a sentence index module, an abstract-type search module and so on. The search method comprises the following steps: (1) catching the web on the web page, and generate statement index; (2) generating a summary-style search results. The system can be used for general-purpose search engines or specialized search engine system, can also be configured as a specific user or user group to provide a summary of the desktop search service system or a remote service system or configured to apply to cell phones and other mobile communications equipment information search platform and so on. Compared with the existing technology, to users of the invention can be more concise, more informative, more relevant, more user-friendly search results.

The invention discloses a data table query method and device, terminal equipment and a storage medium. The data table query method comprises the following steps of: obtaining a data query instruction,wherein the data query instruction comprises a middle table ID and a query index dimensionality; obtaining a target middle table corresponding to the middle table ID on the basis of the middle tableID, wherein the target middle table comprises at least two original index dimensionalities and index dimensionality numerical values corresponding to the original index dimensionalities; querying thetarget middle table on the basis of the query index dimensionality so as to obtain the index dimensionality numerical value of the original index dimensionality corresponding to the query index dimensionality, and taking the index dimensionality numerical value as a target dimensionality numerical value. The data table query method is capable of improving the response time while improving the datatable query efficiency.

The embodiment of the invention discloses a multi-table association query method, device and equipment. The method comprises the steps of obtaining a first query statement; Obtaining a second query statement; Wherein the query conditions in the first query statement and the second query statement have the same fields; Estimating a first query cost of the first query statement; Estimating a secondquery cost of the second query statement; Determining the minimum query cost; According to the query statement corresponding to the minimum query cost, performing query to obtain a first query resultset; Rewriting another query statement according to the first query result set; Querying according to the rewritten query statement to obtain a second query result set; And obtaining an associated query result set according to the first query result set and the second query result set.

The embodiment of the invention provides a method and device for acquiring request data in a multi-core virtual machine system. The method includes the steps that when access reading performed according to a data reading request fails in a local buffer memory, whether data requested by the data reading request are data shared by a client virtual machine and a management virtual machine or not is recognized; when the requested data are the shared data, a buffer memory corresponding to the management virtual machine is determined; the requested data are searched and acquired in the determined buffer memory. The searching range for acquiring the requested data is shrunken, and the efficiency for acquiring the requested data in the multi-core virtual machine system is improved.

The invention provides a query and storage method, device and equipment based on a database cluster, and relates to the technical field of computers, in particular to the field of big data and database management. The specific implementation scheme is as follows: determining target index information according to a query condition of a query request; determining a target storage area corresponding to the target index information from a plurality of storage areas by utilizing a root index server; determining a target storage node corresponding to the target index information from a plurality of storage nodes included in the target storage area; and sending the query request to the target storage node to obtain target data. According to the technology disclosed by the invention, the query efficiency and the query accuracy are improved, and the utilization rate of a database cluster on computing resources is improved.
