Middleware Overview
Information Systems and the level of integration reflects an enterprise, a department, and the whole level of national construction.The face of complex and ever changing online world, middleware has become a tool for comprehensive integration of information systems.
Following the operating system, middleware and database management system with the network after the rise and development of a new kind of basic software, can be regarded as the nodes in the network operating systems, network applications under a layer of support software.
Compared with stand-alone applications, Web applications are faced with the question open, evolution, distribution, autonomy and heterogeneity.As a support network applications, middleware, must support on-demand and change, to adapt to the online world and its applications development and changes in the distribution network throughout the autonomous, heterogeneous information systems effectively integrated into an integrated system.
Computer information systems is the use of computer acquisition, storage, processing, transmission and management of various types of information, and to provide information services to human-computer interaction computer applications, is a computer hardware, software and related applications made in the integration of personnel organizationsystem.The information systems are distributed in various parts of the Internet.
Wei support the comprehensive integration of information systems, a new generation of middleware is typically uses the distributed object technology, and soft Bus Plus software component of the overall structure of the object agent, Xiao Xi agents, adapters, and devices such as Ji Zhi Bao Zhuang, and information systems of the Ji Ben Wei Raostructure, the establishment of the infrastructure on the basis of middleware, application software and then in-depth resource layer, business layer and presentation layer build applications middleware, specific applications for the establishment of the final field of application framework (or platform) to support the full range of informationcomprehensive system integration.
Following the operating system, middleware, database management system, the network technology with the development and application of a constant-depth basic software.Middleware can be classified based middleware, application middleware and application framework for three types of areas.Among them, the application integration middleware main data sources, application resources and integration, business process integration, portal integration middleware.
Three key middleware market
1, 2007, the domestic middleware market, the traditional single-function middleware such as security middleware, transaction middleware product to shrink.
With the deepening of enterprise information, the traditional single-function middleware, can not provide enterprise customers an integrated complex business needs.Provide a complete integrated functionality of middleware products, a necessary requirement.Such as the commonly used Java application server platform, has integrated most of the traditional middleware features such as transaction processing, security authentication.However, in traditional industries such as banking, telecommunications, these industries some business functions and performance have special requirements, therefore, the traditional single-function middleware of middleware such as transaction demand for a long time.
Second, the traditional workflow technology (WorkFlow) and CORBA-related technologies.
With the SOA concept of promotion and product and market development, Web services related standards mature, the corresponding products, technologies and open source to achieve a rapid development.Services to create, call and service orchestration (BPEL) also have a mature and reliable product, which is the traditional workflow products and related technology products CORBA cause a strong impact.
Third, the top Web development technologies, Java and.Net have been greatly developed, Java areas such as Struts + Hibernate + Spring, JSP + Servlet + EJB, JSF, etc..NET areas such as ASP, COM, C # and so on.The rapid development of these technologies, will gradually phase out the traditional PHP, CGI and other Web development technologies.
The integration of e-government tide
With the deepening of enterprise information technology and technology of the Fa Zhan, 在 2007, a number of the original "Too" technologies and products will gradually market the customer Hu Jie Shou, such as enterprise application 集成 (Enterprise Application Integration, EAI) Kaifa Platform, Web 服务related technologies and their products, artificial intelligence software, such as expert systems, decision support systems and so on.The new technology and products will continue to emerge, to effectively meet market and customer needs, such as for B2B applications and integrated development platform and tools, service-oriented component architecture (Service Component Architecture, SCA) 协议 of products.
To the Ministry of Agriculture, "Information Resources" and "National Information Network" project as an example.In the past, due to the limited construction of the early maturity of the technology, and various subordinate units in the information system set up time, application of technology and planning is not uniform, the Ministry of Agriculture within the overall heterogeneous information environment, information island widespread.
And traditional information sharing and exchange by e-mail, not only the workload, duplication and inefficient, time is not strong, affecting the effectiveness of information services.The exchange of data through the use of messaging middleware platform, the Ministry of Agriculture, "National Agricultural Information Resources website," and "National Information Network" Channel of building a truly cross-system, unified data model construction, to achieve their IT environmentthe integration of information resources, not only solve the manual entry repetitive tasks such as heavy Er but also accelerate the national agricultural flow of information and resources around the complementary characteristics, ensuring environmental Xia Fen Bushi Shixianxinxi Shared security, high efficiency, integrityand reliability, but also to ensure the integrity of the business.
Technically, service-oriented software architecture, SOA will become the basic framework of next-generation network services, middleware architecture based on SOA is middleware is an important direction of development.In the SOA framework, the middleware layers can be the basis of shared components and business functions of each component can be packaged as a Web service to support the integration and coordination across functions.
From a market point of view, middleware development, a prominent feature of the rise of domestic middleware.The pattern of international giants dominate the world are being broken, a large number of independent intellectual property rights of domestic middleware vendors rise to the development of China's middleware market has brought to life.
In fact, both the middleware is a common focus, but also pay attention to the field of personality, level of understanding of the industry vendors for the customer is very important.With oriental Technologies, represented by the rise of domestic middleware companies, especially e-government demands on the middleware climax, national firms have welcomed the development pattern in the market turning point.
More importantly, the integration of e-government tide, to bring new opportunities for domestic middleware vendors.According to related statistics, in 2005 the market scale of China's e-government to reach 478 billion yuan, up 16.3 percent; ministries, provincial, prefecture-level and county government web sites have rate reached 93.4%, 90.3%, 93.1% and 69.3%.According to analysis, the scale of e-government investment is expected to exceed 50 billion this year, of which the ratio of about 3% of the middleware.
Strength of domestic and foreign middleware there is a gap
Therefore, only the area of e-government needs middleware market size of more than 1.5 billion have here does not include the large demand for middleware SMEs.There can not be overlooked is that the Government has been encouraging the development of national software companies, e-government is also sensitive areas, at the same cost under the condition of some middleware market tilt is almost inevitable.
At present, the beginning of e-government practice, the government has more than 200 industrial projects to benefit from domestic middleware.These projects, to break the constraints of time and the fragmentation of the constraints, and modernization of government and scientific management provided strong technical support.
Today, China's information technology application phase of construction began to be associated between the various types of information resources, integration, collaboration, interaction and on-demand service, which is middleware for the development of a huge space.At present, the network application middleware gradually based middleware, application middleware, application framework and other three levels of competition and the formation of intense product market competition.
Overall, the overall strength of domestic middleware companies and foreign companies are still large gaps.Despite that the maturity of the domestic middleware products no problem, but it is widely accepted middleware products domestically, but still a very long process.Of course, domestic middleware vendors and their products also have very obvious advantages, closer to the practical needs of the State of information has accumulated rich experience in middleware applications, middleware products can be made practical and ease of use is more close to the localof market demand, technical support and services also have a considerable advantage.You can see, domestic middleware has been widely applied successfully our government, transportation, finance, securities, insurance, taxation, telecommunications, mobile, education and other industries or areas for construction, and construction of large-scale applications can not be the missing link.
In the base software, if the operating system and database management system independent R & D, we have lost a lot of opportunities, then cut into the middleware provides us a good opportunity for infrastructure software.This is because the middleware technology is an open technology, operating systems and network applications ranging from the vast expanse of territory between the middleware are the ride of the territory.
So far, the world has not yet emerged from the monopoly role of middleware products, and our early start in the middleware technology, progress was faster.863 such programs in the state support, the National Defense University, Chinese Academy of Sciences software, Peking University and Beijing University of Aeronautics and Astronautics and other domestic research institutes have developed a high degree of product, with the international advanced technology, the outcome of simultaneous development of middleware; Chinahas emerged in the creative software middleware, TongTech, Kingdee middleware and a number of professionals engaged in the development of middleware products company, and in the financial, telecommunications, transportation, government, military and other fields were many successful applications, has made clearsocial and economic benefits.
In research institutes and software enterprises, the results achieved at least four National Science and Technology Progress Award.Along with the deepening of information construction, we have reason to believe that: with independent intellectual property rights of domestic middleware results and are sure the information construction in China play an increasingly critical role.
