SAP NetWeaver Process Integration (SAP PI) 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. Before the current version, SAP PI was called SAP Exchange Infrastructure (SAP XI). Like other NetWeaver components, SAP PI is compatible with software products of other companies. SAP calls PI an integration broker because it mediates between entities with varying requirements in terms of connectivity, format, and protocols. According to SAP, PI reduces the TCO by providing a common repository for interfaces. The central component of SAP PI is the SAP Integration Server, which facilitates interaction between diverse operating systems and applications across internal and external networked computer systems. PI is built upon the SAP Web Application Server. First release of SAP Exchange Infrastructure was XI 2.0. Later on, releases 3.0, 7.0, 7.1, 7.1 EHP1, 7.3 and 7.31 followed. From release 7.0 onwards, SAP Exchange Infrastructure has been renamed as SAP Process Integration (SAP PI). ==Single Sign-On== SAP NetWeaver PI allows for Single Sign-On through SAP Logon Tickets〔(Single Sign-On Configuration - Procedure for PI Web Components )〕 and x.509 certificates. Certificates allow for the usage of Secure Network Communications (SNC) and Secure Socket Layer (SSL). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SAP NetWeaver Process Integration」の詳細全文を読む スポンサード リンク
