Embodiment Construction

[0029] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0030] Such as figure 1 Shown, the recovery method of the database data of order level of the present invention comprises the following steps:

[0031] Step 101, for a single target order, serialize relevant data at the order level and save it in a local database;

[0032] Step 102. When restoring the target order, query the local database according to the order to obtain the order-level saved data of the target order after serialization;

[0033] Step 103, comparing the acquired saved data with the current order data of the target order, and judging whether the current order data needs to be updated, and if so, execute step 104;

[0034] Step 104, using the current order data of the target order to update the current order data.

[0035] Wherein, in step 101, the serialized data is stored persistently. Data persistence is ...

Abstract

The invention discloses a data recovering method and system for an order-level database. The method comprises the steps that S1, as for a single target order, serialization treatment is carried out onrelated data of the order-level, and the related data is stored in a local database; S2, when a target order is recovered, the local database is queried according to the order, and the stored data ofthe order-level after the serialization treatment of the target order is acquired; S3, the acquired stored data is contrasted with current order data of the target order, it is judged whether or notthe current order data needs to be upgraded, and if yes, S4 is executed; S4, the current order data is upgraded by utilizing the current order data of the target order. According to the recovering method, the queried data by using order querying conditions is utilized to be contrasted with the previous queried data, it is judged whether or not data of the current table is consistent, the current data is upgraded, data recovering processes are simplified, so that the data recovering only aims at the order level and does not affect other data, and the data recovering efficiency is improved.

Description

technical field [0001] The invention relates to a technology for restoring data in an order-level database, in particular to a method and system for restoring data in an order-level database. Background technique [0002] In the prior art, database restoration is mainly processed by inserting all the data in the full data table, but this method is costly and time-consuming, and affects a wide range of data. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an order-level database data recovery method and system in order to overcome the defects of high cost and time-consuming database restoration in the prior art and affect a wide range of data. [0004] The present invention solves the above technical problems through the following technical solutions: [0005] The invention provides a method for restoring database data at an order level, comprising the following steps: [0006] S1. For a single target order, ser...
