enterprise information System. The JCA invokes the public client interface (Common client Interface,cci). CCI is an application developer and client program interface that can connect and access back-end systems together. It is a low-end API similar to JDBC. CCI manages the flow of data between applications and systems without allowing us to see what the container and application servers do. CCI is designe
applications from October 11, May this year for two weeks (a total of 10 units and 40 hours ), currently, only trainees in North America and Europe are allowed. It is worth noting that Mark Shuttleworth, the founder of Ubuntu, personally teaches (as one of the dedicated instructors ). The fee for Beta courses (started in May 4) is USD 1,200. For general courses (started in July 6), plus the UVT0001 certification exam, the fee is USD 1,380.50. In fact
Summary Today, UML has been used to model software systems for years. However, I rarely see detailed discussions or examples of modeling and technology for modern software systems. For example, modeling applications and their deployment requires the development of various prototype systems and the need to use an organized approach to design the scope and layout of the diagram to make it work. Modeling is particularly important in complex environments
Abstract: This article focuses on how to understand the extension of Java applications and different types of extension techniques and specific techniques, and introduces some general extension strategies for Java enterprise applications.To be honest, "extensibility" is a comprehensive and detailed topic that is often not fully understood. It is generally thought that extensibility is synonymous with high a

In this new environment, developers are responsible for organizing business processes in the various application services mentioned above that may be developed and published to the network by other teams and organizations, which may use different implementation technologies or line-of-business application

An EIS (Enterprise Information System) is being developed recently. Many colleagues believe that the B/S technical architecture should be used.ProgramNo client deployment is required, and maintenance is simple. The client can be easily used with any browser, regardless of the WAN or LAN. Objective analysis: the current structure is relative to the B/S structure (there is no "opposition" here. In fact, many enter

As the data size increases and the data complexity increases, people prefer to be able to process multiple types of applications in a cluster. This is also the background of Hadoop 2.0. Some people think that YARN is essentially a new Hadoop operating system, which breaks through the performance bottl
