Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic diagram of a data management system 100 based on a big data technology according to an embodiment of the present invention, where the data management system includes a login module 101, a data collection module 102, a data transpose module 103, a source metadata sensing module 104, a data desensitization module 105, a monitoring and early warning module 106, and a web management module 107.

Specifically, the login module 101 is used for a system administrator to log in to the data acquisition platform through a user name and a password.

By utilizing the same login process used by the service, the user does not need to perform a separate login process in order to login to the application, which is different from the service login process. Once a user logs into an application, the application may perform one or more operations on behalf of the user with respect to the service. The operation may be performed using the identity with which the user has been associated within the application through a "shared" login process.

The data acquisition module 102 is configured to read a database background log, database environment variable information, and a system view, analyze the background log and the database system view through a data analysis program according to real-time changes of service data, analyze real-time incremental data through a data acquisition requirement service table, and support a relational database.

The data transpose module 103 is used for a stream-oriented computing method of a large data processing framework, and can synchronize incremental data and full data. Meanwhile, real-time incremental data can be accessed to a big data environment.

The source metadata sensing module 104 is used for automatically sensing the change of the table structure when the table structure of the data source is changed, adjusting the version number of the data message, and notifying a downstream system through a kafka message and an email.

Kafka is an open source stream processing platform developed by the Apache software foundation, written in Scala and Java. Kafka is a high-throughput distributed publish-subscribe messaging system that can handle all the action flow data of a consumer in a web site. This action (web browsing, searching and other user actions) is a key factor in many social functions on modern networks. These data are typically addressed by handling logs and log aggregations due to throughput requirements. This is a viable solution to the limitations of Hadoop-like log data and offline analysis systems, but which require real-time processing. The purpose of Kafka is to unify online and offline message processing through the parallel loading mechanism of Hadoop, and also to provide real-time messages through clustering.

The data desensitization module 105 is used for desensitizing the identity card, the system amount, the name and the account number to data which is relatively privacy sensitive in the data message in real time. Data desensitization refers to data deformation of some sensitive information through desensitization rules, and reliable protection of sensitive private data is achieved. Sensitive information is shielded by means of a data desensitization technology, and the original data format and attributes of the shielded information are reserved so as to ensure that a system or an application program can normally run in the development and test, data analysis and data trial calculation processes of desensitization data. Data desensitization can be directly replaced, desensitization and salt addition are performed, and a regular expression is adopted, and developers are supported to custom develop jar package personalized desensitization.

The monitoring and early warning module 106 is configured to check the real-time traffic amount of the data stream and the data delay condition, and when the data traffic is abnormal or the data delay is large, configure a rule to set an early warning policy, send a mail or a short message to alarm and notify a person responsible for the order in time.

The Web management module 107 is used for managing a login module, a data acquisition module, a data transposition module, a source metadata learning module, a data desensitization module and a monitoring and early warning module in the form of a Web system.

Referring to fig. 2, a reference schematic diagram is shown for a login method of a data management system based on a big data technology according to an embodiment of the present invention, as shown in fig. 2, a user or an administrator may log in a big data management system platform for operation in a manner of a user name 201 and a password 202, and at the same time, some new users may also log in 204 to the big data management system platform for operation by registering 203 the user name and the password.

Optionally, the provided multi-tenant management can not only manage resources of each tenant, but also provide various services to the tenant, and the tenant first needs to apply for resources, for example: storing resources, computing resources and the like, and normally using various services provided by tenant management after successfully applying for the resources. Based on the above, the resource information may be information such as the resource amount of the storage resource, the resource amount of the computing resource, etc., requested by the target tenant, for example, the resource amount of the database resource, etc.

Please refer to fig. 3, which is a flowchart of a data management method based on big data technology according to an embodiment of the present invention, and as shown in fig. 3, the data management method based on big data technology includes the following steps:

step 301: the method comprises the steps of reading a background log of a database, environment variable information of the database and a system view, analyzing the background log and the system view of the database through a data analysis program according to real-time changes of service data, analyzing real-time incremental data through a data acquisition demand service table, opening program full acquisition configuration in an encrypted data file if the service needs full data acquisition, performing full data acquisition, and automatically performing incremental data acquisition after the acquisition is completed.

Step 302: accessing the real-time incremental data to a big data environment according to a template configured by the data acquisition module; when the data message is changed, the version number of the data message is adjusted, and a downstream system is informed;

step 303: and checking the real-time flow quantity of the service data flow and the data delay condition, and setting an early warning strategy when the data flow is abnormal or the data delay is large. When the data flow is abnormal or the data delay is large, sending mails or short messages to alarm and informing persons responsible for the orders in time through the early warning strategy.
