The invention relates to the technical field of database management and data migration, and discloses a database metadata migration method, device, equipment and medium, comprising: configuring a metadata type mapping correspondence between a source database and a target database, establishing a source database read connection and a target database write connection, and obtaining a source data definition statement of the source database, storing the source data definition statement in a standard format, reading the source data definition statement from the intermediate storage medium, converting the source data definition statement into a target data definition statement conforming to the grammar specification of the target database, and finally executing the target data definition statement in the target database to complete the creation of the metadata object. By introducing the metadata type mapping corresponding relation and the standardized storage mechanism, the metadata difference between the heterogeneous databases is converted into a conversion process capable of being automatically processed, so that manual intervention is reduced, the migration error rate is reduced, and the automation level and reliability of database metadata migration are improved.

The invention relates to an online file system error detection method and device, belongs to the technical field of file system detection, and solves the problems that in the prior art, file system error detection and repair consumes too long time, shutdown is needed, and service continuity is affected. Comprising the following steps: acquiring a path of a to-be-detected file system, and further acquiring the type of the to-be-detected file system; based on the path and the type of the to-be-detected file system, super block metadata of the to-be-detected file system is read, and then global information of the to-be-detected file system is obtained; obtaining the reading rate of each metadata type based on the global information of the to-be-detected file system; and performing metadata detection on the to-be-detected file system based on the type of the to-be-detected file system and the reading rate of each metadata type to obtain a metadata detection result. And online and efficient error detection of the file system is realized.

The application provides a metadata-based railway engineering ECM management method, system and device, steps of the method comprising: performing primary coding and secondary coding on railway metadata types based on an international dictionary framework; establishing connection of data nodes and constructing a connection system; a document management stage of railway engineering involves multiple types of engineering construction nodes, and metadata and unstructured data required to be managed by engineering construction nodes of the same type are different in different document management stages, each engineering construction node corresponds to a data node, and in the same engineering stage document management stage, the data node corresponding to the lower-level engineering construction node inherits the data work authority of the higher-level data; whether a data instruction is effective is determined based on the work authority, if effective, the basic data is processed based on the data instruction, and is shared in each data node, and in each document management stage, metadata, authority data and unstructured data contained in the basic data are uniformly managed.

The application discloses a metadata-based knowledge graph processing method, comprising the following steps: S1) constructing a data unit taking metadata and attributes thereof as a unit; S2) classifying metadata by dividing metadata types according to enumeration types; S3) establishing corresponding documents according to different types and indexes of the metadata, wherein the documents contain unique identifiers of the metadata and metadata attributes; S4) forming a relationship node for each metadata and attribute thereof and storing the relationship node in a mesh mode; and S5) performing quick retrieval based on the relationship node of the metadata. The metadata-based knowledge graph processing method can reasonably store a metadata mesh structure and better perform retrieval and analysis.

This application discloses a method for classifying metadata types, as well as an electronic device and a computer-readable storage medium. The solution provided by this application includes: acquiring field information of metadata in a target big data environment; constructing a target graph network based on the field information, wherein nodes in the target graph network represent metadata, and edges represent field information associated with two corresponding connected metadata; determining the weights of the field information of the metadata in the target graph network; training a node type discrimination model based on samples and labels determined by the node data corresponding to the nodes in the target graph network, wherein the labels include the application type of the metadata represented by the node corresponding to the target big data environment, and the sample features include the field information of the metadata represented by the node; and classifying the nodes in the target graph network into application types based on the type discrimination model.
