In 2006, SAP released the enterprise-level SOA application product mysap ERP 2005. The most frequently asked question is: what are the characteristics of SAP enterprise-level SOA products? In fact, the answer is obvious. SAP is not a pure technical platform, but a business platform that carries a wide range of enterprise-level SOA applications. When talking about enterprise-level architecture, there should be two meanings: first, we should understand how to best organize business processes, start from the business objectives, and run through the entire complex business process design; the second is how information technology supports enterprise organizations and related business processes. SAP has nearly 30 years of experience in commercial software and business processes. Her SOA product is a pure technical platform or technical middleware, unlike other similar products, its unique characteristics and advantages are its rich business content, which is applicable to applications and business processes. Looking back on the development history of the past three years, sap has a clear SOA product strategy. At the beginning, it was symbiotic with applications. In 2004, we concentrated on developing the NetWeaver technology platform based on open standards to build a solid technical foundation for SOA products. By 2005, SAP had years of business experience on the technical platform, from the original application products, many services are identified and re-packaged to form the Enterprise Services repository. In 2006, the mysap ERP 2005 product was released after all applications were transferred to a service-oriented architecture. All applications included in the product were built from services in the Enterprise Service knowledge base, the integration between applications is also based on the standard interface defined in it. That is to say, before helping customers migrate to a service-oriented architecture, SAP first transfers all its products to SOA and provides the Enterprise Service Knowledge Base as a data dictionary for service reuse. Therefore, when customers get SOA products, they not only get technical platforms and tools, but also application products that can be used immediately, more importantly, they can immediately make business process innovation on the application products composed of services, and reconstruct and model the process according to the needs of business process practices. For example, SAP released a Lego (LEGO) building house. This house is like a business process of an enterprise, and each Lego building block is like a service in the enterprise service knowledge base, after the customer obtains the house, they can use it immediately or make some changes, such as re-constructing the garage part, or even re-constructing the whole house using these blocks. This transformation often happens along with the changes in the enterprise's operating environment and business needs. Reliable building blocks ensure that the transformation can be completed quickly and reliably, and business users are the subjects of such transformation, there is no need to involve too much technical details, or to understand how Lego blocks are built. Assuming that the customer only obtains a technical platform and tool, it is not easy for the customer to complete the SOA reconstruction of the enterprise application first. From the perspective of applications, how to divide services, identifying what is necessary services, abstracting General Services, determining appropriate service granularity, and defining stable service interfaces are all difficulties in SOA reconstruction. Over 30 years of accumulated business process experience, sap has a great advantage in this respect. Through the Enterprise Service knowledge base, we have solved most of these difficulties and shared them with customers, we hope to bring a relatively high SOA implementation starting point to our customers, reduce the pain points of change, and quickly obtain benefits from SOA. Many companies in the industry tend to choose sap when deploying SOA, mainly focusing on the Performance of sap soa at the application layer. SAP focuses on applications, we have always been committed to making our SOA applications more flexible and available, especially focusing on business processing models and Business Process customization.
