NaXDB - Realizing Pipelined XQuery Processing in a Native XML Database System

Supporting queries and modifications on XML documents is a challenging task, and several related approaches exist. When implementing query and modification languages efficiently, the actual persistent storage of the XML data is of particular importance. Generally speaking, the structure of XML data significantly differs from the well-known relational data-model. This paper presents the prototypical implementation of NaXDB, a native XML database management system (DBMS). A native approach means the XML data is stored as a hierarchical tree of linked objects. NaXDB is implemented as a MaxDB by MySQL kernel module and thus inherits several DBMS functionality. Furthermore, NaXDB uses objectoriented extensions of of MaxDB by MySQL to store the tree of linked objects. NaXDB implements a large subset of the query
