The application discloses a horizontal table splitting method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring the service type of all data of a service table, performing a horizontal table splitting operation on the service table according to the service type to obtain a plurality of sub-tables; establishing the implementation class of each sub-table and the index value corresponding to the implementation class according to the service type of each sub-table, and storing the implementation class of each sub-table into a spring container, wherein each implementation class shares one data access object interface; associating the index value with a preset proxy class interface, and making the proxy class interface inherit the data access object interface in the spring container, so as to find the implementation class of the corresponding sub-table in the spring container through the index value. The application solves the technical problems of high repeated code amount and redundant code amount and low code flexibility in the current table splitting.

This application discloses a data transmission method and an integrated management platform for a comprehensive management platform, relating to the field of data transmission. The method includes: receiving a user request sent by a user through the Bootstrap front-end interface and routing the user request to the corresponding control layer; the control layer parses the user request, determines the business logic to be executed, and calls the corresponding business layer method, and determines the data operation flow of the data access object layer through the business layer; the business layer calls the corresponding DAO method according to the data operation flow; the data access object layer determines the target database in at least two databases through database query instructions, and performs a query operation in the target database according to the database query instructions to obtain the query results; the data access object layer packages the query results to obtain a data package, and returns the data package to the Bootstrap front-end interface for display through the business layer and control layer level by level.

The embodiment of the invention discloses a system, a method, equipment, a device and a medium for providing data. The system includes a data acquisition module deployed in a WAMR of a device and configured to obtain data from a data source; the data caching module is deployed in the WAMR and is configured to cache the data; and a data providing module deployed in the WAMR and configured to receive a data providing request from a data access object, read the data from the data caching module based on the data providing request, and provide the data to the data access object. By integrating a cache mechanism in the WAMR, the frequently accessed data can be effectively stored and retrieved, so that the time delay is reduced, the resource utilization rate is optimized, and the method is particularly suitable for a resource limited device.

The application relates to an industrial time sequence data processing method and device, a terminal and a storage medium. The method comprises a data organization storage process, which comprises the following steps: storing all time sequence data access objects into a relational database for time sequence data access objects of measured points; collecting industrial sensing data and converting the industrial sensing data into industrial time sequence data piece by piece, wherein the industrial time sequence data comprises time sequence data access identifiers, and each time sequence data access identifier is associated with a time sequence data access object; storing the industrial time sequence data into a time sequence database, and generating and sending corresponding time sequence data storage notification after storage is completed. The scheme of the application realizes additional data analysis and processing information by using the configured time sequence data access object, provides an index for data calling in a subsequent data analysis process by using the time sequence data access identifier, effectively saves storage resources of the time sequence database, and greatly improves data access efficiency during operation of the scheme.

The invention provides a database migration method and device, electronic equipment and a computer storage medium, and the method comprises the steps: marking a data access object layer interface method needing to be migrated through a non-intrusive annotation, and obtaining a target data access object layer interface method; intercepting a target data access object layer interface method in real time; when any target data access object layer interface method is intercepted, asynchronous double-write logic is executed; the asynchronous double-write logic adopted by the invention is as follows: when a main thread executes original write logic and write source database operation, an asynchronous thread acquires an instance of a target data access object layer interface method and performs write target database operation; the asynchronous double-write logic further introduces a dynamic routing strategy, and the dynamic routing strategy is that a data source operated by a host process is gradually switched to a target database in an amount-increasing mode according to a flow proportion, and a data source operated by an asynchronous thread is gradually switched to a source database. And the efficiency and the reliability in the database migration process are effectively improved.
