Problems solved by technology

However, this traditional technical implementation can only be applied to the situation where the amount of data records that need to be updated is small, because when the amount of basic data that needs to be updated reaches 100,000, one million or even more, these records will be downloaded each time through the wide area network. The time required for the data will be as high as tens of minutes or even several hours. During this period, the user must wait and cannot perform business operations, which seriously affects the usability and user experience of the program.

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] figure 1 A software management system based on a three-tier architecture can usually be divided into three parts: Database server part: It is to install common database systems, such as common SqlServer, Oracle, DB2, etc.

[0015] Application server part: It is responsible for the specific business realization, it acts as a bridge between the user program and the database, defines and provides various interfaces for the client program to call. The application server (Application Server) and the database server (Database Server) can be in the same physical machine, or they can be located on different machines.

[0016] Client program part: it is oriented to end-users. There can be different client programs according to different functions, but all must be connected to the application server to form a star structure, and call various data interfac...

Abstract

The invention provides a three-tier architecture based method for optimizing incremental update of system data. The method is characterized in that the system comprises a database server, an application program server and a client program; after basic data is successfully downloaded by a client, the downloaded basic data generates a buffer file on the client, and when the client program starts next time and requests basic data update to the application program server, the application program server compares recorded operation time stamps, and downloads the changed data from the database server. Therefore, the time for updating the system basic data from the database server to the client is greatly shortened, and even is omitted, and the integral performance of the system is improved.

Description

【Technical field】 [0001] The invention relates to an optimization method for incremental updating of system data based on a three-layer architecture, especially in the field of software management systems. 【Background technique】 [0002] In the process of developing an enterprise data reporting and reporting system project, since the entire system must conduct business operations through a wide area network, the final development plan is that the system architecture adopts a three-tier layout, namely: client program (Client) - application server (Application Server) - Database Server (Database Server), after different client programs are connected to the application server in the center through the wide area network, various business operations are performed through data communication with the application server. In this typical three-tier layout, the client does not store data. After each startup, it needs to update various types of latest basic data from the database serve...
