“…Some of these systems use relational DBMS back-ends and are referred to as XML Databases (not to be confused with XML Database engines, which use XML documents as the fundamental unit of storage). The advantage of using DBMS back-end includes the support for ACID, scalability and transaction control but extends to XML-related functionality, e.g., updates (Müldner et al, 2010) and parallel implementations (Müldner et al, 2012).…”

The verbose nature of XML requires data compression, which makes it more difficult to efficiently implement querying. At the same time, the renewed industrial and academic interest in Column-Oriented DBMS (column-stores) resulted in improved efficiency of queries in these DBMS. Nevertheless there has been no research on relations between XML compression and column-stores. This paper describes an existing XML compressor and shows the inherent similarities between its compression technique and column-stores. Efficiency of compression is tested using specially designed benchmark data.
