What is SAP Xi?
SAP Exchange Infrastructure (SAP XI) is SAP's enterprise application integration (EAI) software, a component of the NetWeaver product group used to facilitate the exchange of information among a company's internal software and systems and those of external parties. Like other NetWeaver components, SAP XI is compatible with software products of other companies.
SAP calls XI an integration broker because it mediates between entities with varying requirements in terms of connectivity, format, and protocols. According to SAP, XI reduces integration costs by providing a common repository for interfaces. The central component of SAP XI is the SAP Integration Server, which facilitates interaction between diverse operating systems and applications across internal and external networked computer systems.
What is SAP Netweaver?
NetWeaver is an application builder from SAP for integrating business processes and databases from a number of sources while exploiting the leading Web services technologies. Part of the company's mySAP product group, NetWeaver is getting a lot of industry attention as the first fully interoperable Web-based cross-application platform that can be used to develop not only SAP applications but others as well. NetWeaver allows a developer to integrate information and processes from geographically dispersed locations using diverse technologies, including Microsoft's .NET, IBM's WebSphere and Sun's Java technologies.
NetWeaver has been tagged as a product that could help spur industry adoption of Web services. Although Web services are often seen as the development model of the future, the implementation rate has not been high, often because of competition and incompatibility between enabling products. At a January 2003 press conference, Microsoft's Bill Gates anticipated that NetWeaver would increase the adoption rate of Web services.
