the company's billing system and financial system, financial systems and personnel systems are inevitably closely related. In order to reduce management consumption and maximize the reuse of existing investment systems, many enterprises are undertaking enterprise application integration (EAI). Enterprise application integration can be done at different levels: for example, "Data centralization" at the data storage level, "Common data exchange Platf

high availability and scalability in terms of customer, connection management, and so on. Traditionally, the number of customers and their activities connected to an EIS is expensive and the custom adapter lacks the connection management mechanism provided by the application server.Managing security and distributed transactions for many back-end applications is extremely complex and lacks reliable mechanisms. This means that there is now no standard infrastructure solution to provide a more neu

required for the service interaction, including the message format (detailed description of operations), transport protocol, and location. This interface hides the details of implementing the service, allowing the service to be used independently of the hardware or software platform on which the service is based, and the programming language in which the service is written. This allows and supports webservices based applications to become loosely coupled, component-oriented, and across-technolo

So, some people proposed that the application software to face the common problem of refining, abstraction, on the operating system to form a reusable part, for thousands of application software reuse. This kind of technology thought finally formed the middleware such software. First, middleware classification Middleware cla

Example: Spring integration Our example is an enterprise application integration (EAI) scenario, which we will use with a simulation application based on Spring integration. The application has the following characteristics and requirements: An analog source application produces integration-related events and messages as part of their day-to-day transactions and stores them in a data store. Integration even

Traditional web (html/http) technology effectively solves the problem of interaction and communication between human and information system, and greatly promotes the development of the mode of the Business-to-consumer. Web Service (XML/SOAP/WSDL) technology is to effectively solve the interaction between information systems and communication problems, promote the development of B2B/EAI

When you use BizTalk Server 2004 to design an EAI or business-to-business project, creating a schema is a very important link. However, creating schemas manually often makes mistakes. The typical error is that when the input file is placed in the in folder, it disappears in the in folder but does not appear in the Out folder. If you open the log file, there will typically be two to four error messages, such as "error executing the receive pipeline whe

The 4th and important point is that sunopsis is developed in Java, which is consistent with Oracle and helps Oracle incorporate it into its future fusion middleware.Okay, here's some digression, we're going to cut into today's theme, "ETL vs. Elt", which is more like a bet.One side is currently the mainstream ETL manufacturers with their own development of the data engine to complete the extract,load,transfor

on availability-if your application is vulnerable and difficult to debug, refactor, and develop, performance is meaningless. In 4-5 years, we will still have this ambiguous Error "Error: getaddrinfo EADDRINFO", which tells us where the Node's development priority is. It is understandable that when you focus on building the system core, it is easy to miss these things. I believe that users have repeatedly expressed their opinions on such things, but h
