Sedna is a open source database management system designed to store and manipulate XML data directly. It is a native XML database, ie it does not consist of a wrapper that transforms XML data into tuples that are actually stored in a relational database, but stores tags in a tree that directly represents the XML file.

To store an XML tree, Sedna uses blocks of bytes within a file linked to each other by means of pointers stored in turn in bidirectional lists. This approach, followed by other non-relational databases such as Neo4j, allows great scalability because the time to find a child element or attribute depends on the number of children or attributes of the current node rather than the total tree size.
