Problems solved by technology

[0005] At present, many system environments are composed of products provided by multiple developers. The middleware products are only designed for a specific database and application. When there are differences between products or differences between application requirements and system framework changes Post-middleware cannot be enabled
[0006] 2. The encoding and decoding of transmission information is complex
[0008] 3. Data request conflict
[0009] In a distributed system, when the number of applications is large or the data required by the program is updated more quickly, it is easy to cause data conflicts and network congestion, and it is easy to cause the system to run slowly or crash, which becomes the bottleneck of the entire system performance. Similarly, a large number of Database requests create bottlenecks for database requests

Embodiment 1

[0085] Embodiment 1: (hardware embodiment)

[0086] Such as figure 1 As shown, a kind of distributed middleware is made up of request listening module 6, request receiving module 4, result sending module 3, data cache module 2 and data access module 5, is characterized in that data cache module 2 and request receiving module 4 , the result sending module 3 and the data access module 5 are connected; the request monitoring module 6 is connected with the request receiving module 4; the result sending module 3 and the request monitoring module 6 are connected with the application program 7 by the TCP / IP communication protocol respectively, to realize The purpose of information communication; the data access module 5 is connected with the database 8 through ODBC technology, so as to realize the information transmission between it and the database 8 .

Embodiment 2

[0087] Embodiment 2: (method embodiment)

[0088] Such as figure 2 As shown, a data interaction method between distributed middleware and database, the steps are as follows:

[0089] 9) start

[0090] 10) Send and receive requests

[0091] The middleware is divided into two parts: the client and the server. Create a listening program for the client to send database operation requests at the specified port on the server, and create its corresponding data processing service for the received client request information. The determination of the network connection status provides the basis for the system Data communication support, data processing service corrects the sent request information according to the database request coding and analysis technology, if the received request information is mistaken, the client will receive an error message prompt, if the request information is accurate and complete, the analysis information will be submitted to the database info...

Abstract

The invention relates to a data interactive method for a distributed middleware and a database, which belongs to the technical field of distributed system middleware, wherein the distributed middleware consists of a request monitoring module, a request receiving module, a result sending module, a data buffer module and a data access module; the distributed middleware is characterized in that the data buffer module is connected with the request receiving module, the result sending module and the data access module; the request monitoring module is connected with the request receiving module; the result sending module and the request monitoring module are respectively connected with an application program through a TCP / IP communication protocol so as to achieve the aim of information communication; and the data access module is connected with the database by an ODBC technology so as to realize the information transmission of the data access module and the database. The method provides aninteractive method for the distributed middleware and the database with multiplexing, easy resolving, high efficiency and better compatibility and expansibility.

Description

technical field [0001] The invention relates to a data interaction method between distributed middleware and a database, and belongs to the technical field of distributed system middleware. Background technique [0002] With the development of distributed computing systems, middleware technology emerges as the times require. Middleware is a type of independent system software or service program that realizes application interconnection and resource sharing in a distributed system environment. Middleware has become the key basic software of distributed systems. With middleware, distributed application systems can be developed, operated and managed more conveniently. [0003] In the traditional distributed system, the interaction between middleware and database mostly has the following deficiencies: [0004] 1. Not reusable [0005] At present, many system environments are composed of products provided by multiple developers. The middleware products are only designed for a ...
