This invention discloses a dynamic compression-type distributed data storage method, storage system, and apparatus, comprising: setting up a distributed storage node plugin, starting a private distributed storage node, and triggering a content addressing identifier smart contract based on a storage request from an external system; generating a corresponding key pair for the distributed storage node, wherein the content addressing identifier smart contract specifies a blockchain node address; enabling the distributed storage node to adapt to a dynamic distributed network based on the content addressing identifier smart contract; the blockchain node selecting a weighting factor for the stored data and calculating the data value of the stored data; the distributed storage node setting stored data attributes, allocating the entire storage area, reserving storage space for the stored data according to the data value, and determining a default storage period; compressing the stored data according to the data value, data attributes, reserved storage space, and storage period, and storing the compressed data in a database.

The invention provides a storage method and a database system. The method comprises the steps that in response to modification operation of a plurality of data pages, a plurality of log records are generated, and each log record corresponds to the modification operation of one data page; writing the plurality of log records into a log storage node; based on the plurality of log records in the log storage node, updating the plurality of data pages to obtain a plurality of updated data pages; and writing the plurality of updated data pages into a data storage node. According to the scheme, the performance of the database system can be improved.

The application discloses a multi-model reasoning method and device based on a graph structure, a medium and a program product, wherein the method comprises the following steps: querying a task target node in a graph database and starting from the task target node, and performing reasoning path expansion in the graph database according to a corresponding driving model, wherein the graph database comprises a plurality of directed acyclic graphs, and each directed acyclic graph is obtained by mapping metadata of a registered analysis model; generating a task topology execution graph according to model nodes involved in the expanded reasoning path and the corresponding driving model; and sequentially scheduling actual execution of each model node according to the task topology execution graph, and obtaining an explanation result corresponding to the task target node. The application improves the reasoning execution efficiency by explicitly attributing the analysis model and optimizing the reasoning path by using graph calculation, and improves the intelligence, performance and interpretability of multi-model collaborative analysis.

The invention relates to an oyster peptide compound for promoting postoperative recovery, protecting the liver and dispelling the effects of alcohol and a preparation method of the oyster peptide compound. The compound is mainly composed of modified oyster peptide and dihydromyricetin, an antioxidant, a cross-linking agent, an adhesive and a pH regulator are matched, and the stability, bioavailability and release control ability of the oyster peptide are improved through a chemical modification method. The compound has the remarkable functions of protecting the liver, dispelling the effects of alcohol, resisting oxidation and promoting postoperative recovery. Oyster peptide is modified through esterification reaction and has a synergistic effect with small organic molecules such as dihydromyricetin and the like, so that the action effect of the oyster peptide in vivo is improved. The compound disclosed by the invention has excellent performance in the aspects of promoting postoperative recovery, improving the hemostatic effect, enhancing the antioxidant capacity and accelerating biodegradation, has a wide application prospect, and is particularly suitable for the fields of functional foods and health-care products.

The application provides a natural resource asset accounting method and device based on a model operator, equipment and a medium. The method comprises the following steps: in a visual modeling interface, a plurality of accounting operators are selected from a preset operator library in response to a user drag operation, a data flow direction and a dependency relationship between the operators are configured through a connection line, a natural resource asset accounting model is constructed, and a structured machine-readable model description file is converted; the model description file is submitted to a distributed task execution engine for analysis, an executable task graph is dynamically constructed, an accounting task is executed based on the executable task graph by using a Master-Worker distributed node architecture, and an accounting result of the natural resource asset is generated; and based on the accounting result of the natural resource asset, a natural resource asset balance sheet is automatically filled and generated according to a preset report template and a data association rule, so as to solve the problems of high maintenance cost and poor flexibility of a natural resource asset accounting system caused by the fact that accounting logic is fixed in a code level.
