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 distributed middleware is composed of a request monitoring module 6, a request receiving module 4, a result sending module 3, a data cache module 2, and a data access module 5. It is characterized in that the data cache module 2 and the request receiving module 4 , The result sending module 3 and the data access module 5 are connected; the request monitoring module 6 and the request receiving module 4 are connected; the result sending module 3 and the request monitoring module 6 are respectively connected to the application 7 through the TCP / IP communication protocol to achieve Information communication purpose: The data access module 5 is connected to the database 8 through ODBC technology to realize the information transmission between it and the database 8.

Embodiment 2

[0087] Example 2: (Method Example)

[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. The client sends a database operation request listener on the designated port of the server, and the corresponding data processing service is created for the client request information. The judgment of the network connection status provides the basis for the system Data communication support. The data processing service corrects the sent request information according to the database request encoding and analysis technology. If the received request information is misunderstood, the client error message prompt is returned. If the request information is accurate and complete, the analytical information will be sent to the database information Processing service

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 an interactive 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 a 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 has emerged. Middleware is a type of independent system software or service program that realizes interconnection and resource sharing in a distributed system environment. Middleware has become the key basic software of distributed systems. With middleware, it will be more convenient to develop, run and manage distributed application systems. [0003] In traditional distributed systems, the interaction between middleware and database mostly has the following shortcomings: [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 specific database and application. When ther...
