Embodiment Construction

[0025] Embodiments and examples of the present invention will be described in detail below with reference to the drawings.

[0026] The scope of applicability of the present invention will become apparent from the detailed description given below. It should be understood, however, that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are given for purposes of illustration only.

[0027] figure 1 A flow chart of an embodiment of the data synchronization method according to the present invention is shown.

[0028] In step S102, an audit database for synchronization is created in the production environment database, and an audit table for audit is created based on the audit database. The production environment refers to the formal environment of various systems. A system will go through development, testing, pre-launch and launch (ie production). For system stability, usually only one business system is running. In a ...

Abstract

The invention discloses a data synchronization system and a method, and the system comprises a creation module which is used for creating an auditing database for synchronization, and the auditing database comprises an auditing table for auditing; an adding module which is used for adding a trigger in a service table of a production environment database, and the trigger inserts a unique identifierof data related to trigger of the trigger in the service table into the auditing table when being triggered; a calling module which is used for enabling the auditing table to call the API interface of the service front-end processor by taking the newly added unique identification data as parameters; and a storage and modification module which is used for enabling the service front-end processor to respond to the call; storing the unique identification data into a local transfer database; and taking data corresponding to the unique identifier from a service table of a production environment database through the unique identifier, sending the obtained data to corresponding service logic, and modifying the state of the unique identifier data corresponding to the obtained data in the local transfer database to be synchronized. According to the system and the method, efficient data synchronization can be realized, and the consistency of the data is ensured.

Description

technical field [0001] The present application relates to the field of electrical digital data processing, in particular to a data synchronization system and method. Background technique [0002] A medical data solution in the prior art uses the business front-end processor to capture data from the production environment database periodically, for example, every half hour, so as to achieve synchronization. This solution has poor timeliness and poor security. Another solution is to establish a trigger mechanism in the production environment database table to push the data out. However, this method not only affects the performance of the production environment database itself, but also greatly reduces data consistency. Therefore, the prior art solutions for data synchronization in medical Internet systems have the disadvantages of long delay and data loss. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the technical problem to be...
