信息集成关键技术——企业服务总线

信息化技术和信息化应用的快速发展向企业信息集成提出了更高的要求，以往的EAI已经很难符合企业的需要。在以面向服务架构（SOA）为方向的新的集成方式中，企业服务总线（ESB）是集成的关键技术。ESB包括了通信、消息、安全、管理、集成等多方面的技术和功能。有了ESB的支撑，SOA将以往复杂繁琐的集成系统清晰地分为服务、ESB、业务流程三个主要的层次，并且对遗留系统的集成提供支持。尽管现阶段SOA的应用仍有许多局限，但是随着技术的发展和应用的成熟，ESB终究会成为企业应用的必备软件。

Key Technologies of Enterprise Integration:Enterprise Service Bus

Since the fast developing information technology and the application of information requires higher demands in the enterprise information integration,EAI cannot meet the needs of enterprise.Enterprise service bus(ESB),including technology and function such as communication,message,security,management, integration and so on,is the key technology of integration in the new integration manner that takes service-oriented architecture(SOA) as the direction.With the support of ESB,SOA has clearly separated the integrated system into three main levels: service,ESB and business process.SOA can also support the integration of legacy systems.Although there are some limitations in the application of SOA in recent days,with the development of technology and the maturity of applications,ESB will finally become the necessary software that an enterprise application needs.
