Problems solved by technology

However, whether it is incremental backup or data compression, the access process requires a lot of calculations. In essence, time is exchanged for space, and the access performance is not good. Especially in large-scale information systems, the method of creating snapshots is difficult to meet the performance of the system. need

Embodiment 1

[0068] Taking a class of objects as an example, explain the specific process of adding objects, changing objects, deleting objects and obtaining object states one by one.

[0069] As shown in Table 1, the attributes of the object are divided into several attribute groups such as attribute group A, attribute group B, and attribute group C. Among them, attribute group A includes attributes such as attribute A1, attribute A2, and attribute A3; attribute group B It includes attributes such as attribute B1, attribute B2, and attribute B3; the attribute group C includes attributes such as attribute C1, attribute C2, and attribute C3. Each attribute of the object can be any type such as numerical value, text, time, symbol, table shape, professional data, etc.

[0070] Attribute group A corresponds to three object attribute tables of current state table A, historical state table A, and temporary state table A; attribute group B corresponds to three object attribute tables of current s...

Abstract

The invention discloses a data access method of traces left in an electronic government affairs system, includes such steps as S1, classifying objects in E-government system according to correlation between object attributes, S2, establishing object attribute table according to state of object in E-government system, and setting up object attribute table including current state table, history state table and temporary state table, S3, accessing the data in the current state table, the history state table or the temporary state table according to the access instruction inputted by the user. Themethod provided by the invention can save the historical state of the dynamically changing object in the electronic government system, thereby realizing the tracing and searching of the system dynamic data.

Description

technical field [0001] The invention relates to the field of data access, in particular to a data access method for leaving traces in an electronic government affairs system. Background technique [0002] With the popularization of informatization, the application range of information system is getting wider and wider. In some special application fields, it is required that the information system can save the historical state of the dynamic change process of some important objects, so that they can be queried when needed. . [0003] For the preservation of the historical state of dynamic data, the general method is to create a snapshot. When the state of the object changes, copy all the data of the object to create a copy, and record the relevant state information, and obtain the historical state of the object from the copy when needed. This method needs to create a copy every time the object state changes, which requires a lot of storage space. In order to save storage ...
