Problems solved by technology

For example: clients access the database directly (or through stored procedures), and all clients access the database, which is not conducive to security control and difficult to prevent malicious attacks by hackers
At the same time, the network traffic is very large, which is easy to form a network bottleneck
It will also cause database access bottlenecks and too many database connections, which will affect the response speed of the database and reduce system performance.
In addition, the two-tier application architecture has maintenance and expansion issues

Embodiment 1

[0021] The SSL / XML-based database access proxy method of this embodiment is performed in the following steps:

[0022] (1) Deploy the server of the middle tier on Linux, set the connection parameters between the server and the database and the related operating parameters of the server;

[0023] (2) The server retains the connection pool with the database to improve operation efficiency;

[0024] (3) Deploy a middle-level proxy, responsible for the forwarding of requests between the client and the server, and reasonably arrange request routing;

[0025] (4) The user uses the interface provided by the middle-tier client to access the business database.

[0026] The middle layer of the database uses XML to describe data, and the transmission channel supports SSL encryption.

Abstract

The invention relates to a database access method and a database access system, in particular to a database access agent method and a database access agent system based on SSL / XML. An intermediate layer client is an access operation interface for providing a database record set to a final user, which supports inquiry of the database record set, local cache and navigation and updating, deleting and other operations of the database records; an intermediate layer agent is used for linking the intermediate layer client and an intermediate layer server; the intermediate layer agents can be cascaded with each other to provide a data access channel to the database intermediate layer; the intermediate layer server is used for receiving a database access request, analyzing the database operation according to the request, accessing the database and returning the result of the database operation to the intermediate layer client through the intermediate layer agent. The invention can effectively support the database access over a plurality of hosts.

Description

Technical field [0001] The invention relates to a database access method and system, in particular to a database access proxy method and system based on SSL / XML. Background technique [0002] In some current systems, due to the large number of clients, the amount of access and data transmission is relatively large. In order to solve the corresponding bottlenecks and for safety considerations, middleware is often used to form a three-tier (multi-layer) application system. [0003] The two-tier architecture has exposed some problems in practical applications. For example, clients directly (or through stored procedures) access the database, and all clients access the database, which is not conducive to security control and difficult to prevent malicious attacks by hackers. At the same time, the network traffic is very large, which easily forms a network bottleneck. It will also cause database access bottlenecks and excessive database connections, which will affect the response spee...
