not ideal for performance and flexibility. With DB2 9's pureXML technology, XML documentsare stored internally in a parsed hierarchical manner, as a tree; therefore, working with XMLdocuments is greatly enhanced. In 2007, IBM has gone even further in its support for pureXML,with the release of DB2 9.5. DB2 9.5, the latest version of DB2, not only enhances andintroduces new features of pureXML, but it also brings improvements in installation,manageability, administration, scalability and performance, workload management andmonitoring, regulatory compliance, problem determination, support for application development,and support for business partner applications.NOTEThe term "Universal Database" or "UDB" was dropped from the name in DB2 9 for simplicity.Previous versions of DB2 database products and documentation retain "Universal Database" and"UDB" in the product naming.Also starting in version 9, the term data server is introduced to describe the product. A dataserver provides software services for the secure and efficient management of structuredinformation. DB2 Version 9 is a hybrid data server.NOTE
Before a new version of DB2 is publicly available, a code name is used to identify the product.Once the product is publicly available, the code name is not used. DB2 9 had a code name of"Viper", and DB2 9.5 had a code name of "Viper 2". Some references in published articles maystill use these code names.Note as well that there is no DB2 9.2, DB2 9.3 or DB2 9.4. The version was changed from DB29 directly to DB2 9.5 to signify major changes and new features in the product.DB2 is available for many platforms including System z (DB2 for z/OS) and System i (DB2 fori5/OS). Unless otherwise noted, when we use the term DB2, we are referring to DB2 version 9.5running on Linux, UNIX, or Windows.IBMDb2From Wikipedia, the free encyclopediaIBM Db2Developer(s)IBMInitial release1983Stable releaseDb2 Data Server (11.1) / April 12,

These products all support the relational model, but in recent years, some products have been extended to support object-relationalfeatures and non-relational structures like JSON and XML.Historically, and unlike other database vendors, IBM produced a platform-specific Db2 product for each of its major operating systems. However, in the 1990s IBM changed track and produceda Db2 common product, designed with a common code base to run on different platforms.[citation needed]Contents[hide] 1Current supported platforms2History
