The project construction period requires that the Java or .NET development platform has almost no accumulation, most developers have not been exposed to J2EE, or .NET Web development, and other tool development is in dilemma, what should I do? The following is taken from the "Programmer" magazine 200408 "focusing domestic web development platform" "................................................................. The complexity problem of software platforms facing software development, however, due to J2EE itself is not perfect and the fast update of IT technology, developers still have to face a series of complex technologies and standards; more, because J2EE is just one Standard rather than products, various J2EE providers have also differentability, resulting in developers using a platform-developed software that cannot be fully compatible with another platform, for this, to make a large number of migration work; Finally, J2EE application The complexity of deployment and maintenance is also uniform. The tools and techniques are resolved. The Puyuan EOS is a black box J2EE application that enables integrated application development, operation management; EOS emphasizes the use of business, shielding Complex technical details, as well as a large number of basic components and business components that meet the application of rapid construction enterprises. Plus the EOS platform uses technology, development methods and management systems with components to be core, their thoughts and products for current software Enterprises increase management level, reduce business costs and operational risks are important. Software companies have made work, including knowledge and experience, can accumulate and manage components in the form of components, for software companies, usually facing software reuse Poor ability, high risks of personnel flow rate are a good response strategy. If developers want to develop rich visual applications with Java technology, Extra will be a very good choice. Use Extra rich components to be faster Creating a beautiful interactive user interface, operational way is as friendly as a general desktop application, not like traditional web applications, from this to clear, intuitive ways to display a large amount of data information. Membership development methods will greatly reduce developers' thresholds into Java development, even primary technicians, can easily pick up, and create powerful and easy-to-use complex enterprise applications. Use Extra architecture And new development models will bring more exciting new feelings to developers. For vendors who do not want to use their original development processes and development tools, Kono's ideas may be more suitable for them. With business-oriented business Treatment, based on system engineering, automation process, pursuing improvement in software development. Realizing automation of traditional manual development process, for unable automation, does not change the original development method, but providing accessories. All Automatically generated business components can be replaced with handwritten code. Reduce the threshold for developers. For vendors who want to develop web applications on the .NET platform, Jinfu Rui UCML application framework development platform and other platforms are provided based on .NET s solution. We can see that all of these software platforms are often based on certain starting points, and their own technical and performance in certain technical areas. Competition is inevitable, but we still hoped that these manufacturers are competing while considering whether they can carry out some technologies and even commercial integration to launch more powerful complete solutions, and the foreign IT giants are higher, Even leading worldwide technology trends. Finally, we sincerely hope that these domestic Web development platforms can be well developed, and they also hope that domestic application developers can make China's software industry can get a thrive opportunity to face these domestic software platforms.
