The following describes in detail the secure data transfer method, apparatus, device and medium of the data element in heterogeneous data source according to the embodiment of the present application with reference to the attached drawings and the preferred embodiments.
Firstly, an application scenario of the secure data transfer method of the data element in the heterogeneous data source according to the embodiment of the present application will be described in detail.
Different database management systems, file formats, network protocols, etc., result in the heterogeneity of different data sources.
In the data transfer process between heterogeneous data sources, an intermediate process table is often generated, which not only increases the complexity of data management, but also may cause the risk of data leakage. The existing data transfer method often ignores the security problem caused by an intermediate process table in the data migration process, and also comprises the form and form of the data elements and the security of data reading and writing of the data elements in heterogeneous data connection. The existence of these problems makes the data vulnerable to attack during transfer, increasing the risk of data leakage and tampering.
Aiming at the technical problems, the application provides a secure data transfer method of a data element in heterogeneous data sources, which can effectively manage connection information and metadata of a plurality of data sources, and can ensure the security and integrity of data in the data transfer process so as to meet the high requirements of modern enterprises on the security and reliability of the data.
Referring to fig. 1-2, an embodiment of the present application provides a secure data transfer method of a data element in a heterogeneous data source, where, as shown in fig. 1-2, the secure data transfer method of the embodiment of the present application includes the following steps:
Step S1, based on the established connection relation between the data sources and the super management account, obtaining connection information between the data sources and super user information, and registering the connection information and the super user information to a management center through the corresponding data sources.
And step S2, managing the connection process between the data sources through a management center.
In some possible embodiments, the managing the connection process includes:
Step S201, determining and acquiring roles of users according to the development, production and circulation processes of the data elements.
Step S202, according to the role of the user, automatic authorization of the data source or connection rejection are carried out.
And step 203, realizing the automatic on-line and off-line of the data source according to the health state of the data source, and carrying out on-line recovery notification on the access request of the user during the off-line when the data source is on-line.
Step S204, detecting the JDBC connection quantity of the data source, early warning when the connection quantity exceeds 80% of a preset threshold value, sorting the liveness of the current connection users, sending a message notice of possible closing to the connection users with the inactive TOP20%, and executing closing action to the connection users with the inactive TOP20% when the connection quantity exceeds the threshold value. Wherein the criteria for an inactive connected user is set such that no data transmission is detected within 10 minutes.
And step S3, managing the generation process of the data element through a management center.
In the generation process of the data elements, unified super account management realizes unified management of multiple data sources, metadata information of the data sources can be automatically scanned and updated through a management center, and virtual jdbc is directly authorized to access source data through the management center. So as to achieve the data timeliness and effectiveness of the element data generation process and the data source data elastic routing authorization.
In some possible embodiments, managing the generation process of the data element includes:
step S301, periodically scans and maintains metadata information of each data source, and records the scanning time.
Step S302, when the data of the data source is increased, the metadata information of the data source is automatically updated synchronously.
In step S303, the management center periodically scans the heartbeat information of the data source to ensure that the data source is maintained in a usable state.
Step S304, periodically scans the registered data source list to ensure that new data sources can be discovered and used at any time.
Step S305, based on the management center providing the virtual JDBC, the virtual JDBC is automatically routed to the JDBC of the corresponding data source according to the data resource and the metadata information of the data source required in the process of developing, producing and circulating the data element.
And S4, receiving a data query request initiated by the client through a pre-configured task scheduling node, and sending the data query request to a management center.
And S5, the management center queries and analyzes the metadata information of the source data source and the related information corresponding to the target data source according to the data query request, and transmits the analyzed data to the task scheduling node.
The data transmission process can be realized by transmitting the data in a reflection mode or by matching a public buffer layer with a fine grain authority.
And S6, the task scheduling node registers the node task according to the data query request, and executes the node task according to the analyzed data to load the data.
And S7, the client obtains a data loading result of the task scheduling node through the data query request, executes a corresponding user task according to the data loading result, and obtains and writes out a calculation result after the user task is executed.
In the above steps, the data element may be understood that the metadata management platform is isolated from the task scheduling and executing platform during the data transfer process of the heterogeneous data source. The data elements are enabled to receive data query requests initiated by the query clients through the set task scheduling nodes in the heterogeneous database system, and the metadata information of the source data sources and the related information of the target data sources are analyzed through the scheduling node request management center, so that the data elements are ensured not to store connection information of the data elements when the data elements are transferred on the scheduling platform, and the data elements are used immediately. The data element is on the whole task scheduling platform, and only the program knows the metadata information.
Thus, the existence of data elements between heterogeneous data sources can be understood as a flexible data abstraction that represents a collection of immutable, partitionable, parallel-computable elements within, when data conversion is performed. The elastomer is as follows:
(1) Fault tolerance elasticity, namely, the data loss can be automatically recovered;
(2) The elasticity of storage, namely automatic switching between the memory and the disk;
(3) Calculating elasticity, namely calculating an error retry mechanism;
(4) The elasticity of the segments can be re-segmented as needed.
In the data processing process of the data element, an intermediate process table is not generated, a user loads the data before using the data, and the user does not contact a data source, so that the reliability and the safety of the data element in the operation process are ensured.
Based on the technical scheme, the method and the device avoid the limitation that the complicated configuration information of the database depends on personnel management, realize centralized automatic management of the configuration information, enable the configuration of the database to be more consistent and standardized, facilitate monitoring and maintenance, reduce human errors and improve efficiency.
The application provides an elastic data abstraction form, data can be invisible, the risk of improper access or leakage is reduced by avoiding generating an intermediate process table, the safety of the data is protected, the requirement of data storage is reduced, and the efficiency of data processing is improved.
