{{Mark|Updated with Version 9.0}}:
Database In BaseX, two internal representations exist for nodes . * XML fragments are XML generated by XQuery node constructors.* Database nodes which are either :** stored in a persistent databaseon disk;** nodes of a document that has been generated temporarily with {{Code|fn:doc}}, {{Code|fn:parse-xml}} and other functions; or which contained in ** result of a somain-called ''memory update operation. Some operations are restricted to database fragment''. All nodes, but you can convert XML fragments can be converted to database fragments nodes by e. g. applying the an empty [[XQuery_Update#update|update]] or [[XQuery_Update#transform|transform]] expression on operation to a node. Two examples: * Retrieve the internal node id of an XML fragment:

|Returns meta data on all directories and resources of the database {{Code|$db}} in the specified directory {{Code|$path}}. Two types of elements are returned:
