SOA (Service Oriented Architecture) is Service Oriented Architecture, but how is it useful in practice?

   At present, the SOA methodology is truly integrated with customer business, and the core entry point is information integration. The use of information integration products based on SOA architecture, such as ESB bus, service resource registration center, data integration products, process integration products, integrated development tools, Integrating application platforms, etc., can help users achieve data integration, application integration and process integration. The integrated system can realize single sign-on, interconnection, unified architecture and unified standards of multiple systems, which helps to solve the problem of information islands that have plagued enterprises for a long time. For example, in the process of informatization construction for many years, enterprises have accumulated a large number of IT systems such as financial software, ERP software, CRM software, database, OA software, etc. Due to the differences in programming languages, standards and protocols, it is difficult to communicate between these systems. Intercommunication and dialogue have formed the so-called information island problem, which seriously affects the flexibility of the business, especially for the support and maintenance of the IT department. , has taken the lead in the attempt to integrate SOA information.
