The invention provides a local database system and a retrieving and updating method of the local database system. The local database system comprises a local database and a retrieving and updating device. The local database comprises a metabolin nuclear magnetic resonance spectrogram information data table, a metabolin nuclear magnetic resonance spectrogram information domain processing unit and a metabolin nuclear magnetic resonance spectrogram information report form processing unit. When the local database is retrieved and updated, domains of a plurality of related data tables are combined into one domain, a query condition and update contents are input through a window, retrieving and updating are carried out in subdomains of the combined domain through an operation expression, a query result is output through a report form, and an updating result is output through the window. According to the local database system and the retrieving and updating method of the local database system, the data memory space is effectively reduced, and the retrieving efficiency is improved; the metabolin data tables do not need to be directly and repeatedly operated, the operating steps are simplified, the operating difficulty is lowered, and the updating efficiency and the data safety are improved.

The present invention proposes a multi-dimensional automatic vehicle identification method, which includes the following steps: S1. The multi-dimensional roadside sensing device acquires multi-dimensional data of the vehicle, and sends the multi-dimensional data and the time and location information of the acquired data to the sensing data processing platform; S2. The perception data processing platform gathers the multi-dimensional data sent by multi-dimensional roadside sensing devices at different points for a period of time, and evaluates the characteristics of each multi-dimensional data through the data dimension characteristic evaluation unit; S3. The multi-dimensional data association construction unit is in Based on the evaluation of the characteristics of each multi-dimensional data, through the observation and comparison of the diversity of individual vehicle data, the construction of the multi-dimensional data association relationship of individual vehicles is realized, and the confidence degree of the association relationship is given by the association confidence calculation unit, so that Realize vehicle-centered one-car-one-gear.

The embodiment of the invention provides a search method for a cloud storage system. The method comprises the following steps: receiving a first query request sent through user equipment; searching a corresponding object list item in a view according to the first query request, wherein the view is stored in an internal storage of the cloud storage system and corresponds to an object in a data base of the cloud storage system or a file system; and obtaining data of the objet searched by the user equipment according to the searched corresponding object list item. Therefore, the user equipment can directly query the object list item through the view in the internal storage of the cloud storage system without inquiring from containers in the database of the cloud storage resource management system or the file system, so that the data search efficiency is improved.

A coding composition language words storage and dynamic derivation method is characterized by dividing a linear general wordlist into a basic word stem table, a prefix table, a suffix table which are stored in an embedded equipment storage unit, obtaining a combined index of prefix and suffix by the prefix table and the suffix table respectively correspond to a relative index; adding corresponding data structure algorithm to the input engine to search the stem table and the combined index of prefix and suffix by inputting content using keyboards, to produce the stem automatic deformation structure by combining the stem and the prefix and suffix so that the result set of different tense, nature, and number of the stem is derived, and outputting integral words in the display terminal. The invention adopts a more reasonable word data storage structure, thereby effectively compressing the storage space and raising data retrieval efficiency. The invention can be used in man-portable embedded devices and has the advantages of reducing production cost, reducing volume and weight, raising the operating speed, and having broad application prospect.

The embodiment of the present invention discloses a data retrieval method, electronic equipment, and a computer-readable storage medium. Starting from a node in a pre-established retrieval graph, the retrieval is performed in a predetermined retrieval manner to determine a set of candidate nodes and based on the candidate node The collection determines the retrieval results corresponding to the target data. In the embodiment of the present invention, when the similarity between the currently retrieved node and the target data is greater than the first threshold and the node matches the label information of the target data, the node is added to the candidate node set, and the currently retrieved node and the target data When the similarity of the node is greater than the first threshold and the label information of the node does not match the target data, the node is added to the candidate node set with a certain probability. Therefore, the embodiment of the present invention can support the retrieval of nodes that are similar to the target data and have matching label information. data, and can improve data retrieval efficiency.

The invention relates to a search method and system based on bidirectional mapping. By adopting first-grade mapping and second-grade mapping, on one hand, the problem that a user is lack of legal knowledge and cannot position own actual retrieval demand requirements very well is solved; on the other hand, the problem that the evaluation of lawyers practice conditions is not comprehensive, caused by a fact that determination and expressions of causes of action for administration cases in local courts of justice are different, is solved; on the basis of mapping in the two aspects, the butt joint of a user retrieval demand and a retrieval object is further realized, so that the user retrieval demand is accurately positioned, the accuracy of a retrieval result and the data retrieval efficiency are improved.
