Embodiment Construction

[0033] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] figure 1 A block diagram showing a method for implementing data version upgrades according to the present invention, figure 2 It is a system structure diagram of the implementation method of the data version upgrade in the present invention. refer to figure 1 and figure 2 , the method for implementing the upgrade includes: S102, writing the low version database 202 and the version transition library 204 from the low version to the high version into the software system; and S104, importing the low version data into the high version database according to predetermined rules, Thus, the low version database is upgraded to the high version database 208, wherein the data version upgrading method is implemented in the data upgrading agent program 206. The version transition library 204 includes version evolution files in the form of data...

Abstract

The invention provides a method for realizing data version upgrade, which comprises the steps that the data is written in a low version database and a version change base to a software system; through data upgrade agent program, the low version data is led into a high version database, and upgraded to the high version database. In the upgrade agent program, the following steps are required to be performed: the database version number is read; the low version database is renamed, and the high version database is created; in the high version database, rules and functions required to be used for the version upgrade defined in the version change base are established, process information is stored, and all the change rules between the two versions in change rule tables is read; each table is upgraded, and after the data of all the tables are led in, the returning to the upgrade state information of all the tables is performed. The software system realized through the invention can make smooth upgrade to the data, and the system has clear structure and is easy to be realized.

Description

technical field [0001] The present invention relates to a method for upgrading data versions, and more specifically, relates to a method for smoothly upgrading data of software systems based on large-scale database systems in the fields of computers and communications. Background technique [0002] Among the existing software systems, many are based on large database systems (such as ORACLE, SQL SERVER, SYBASE, DB2, etc.) to manage configuration data and other data related to system operation, but because software products are always constantly A new version is launched, and each release of a new version may involve changes in the data structure and related data algorithms, so it is bound to require a smooth upgrade of the old version of the data. At present, many software products need to provide a special upgrade manual when upgrading, and write a special upgrade program to handle it. Such an implementation method not only requires a lot of work, but also has poor scalabil...
