What kind of database should be used with XBRL?
XBRL is a format for exchanging information between applications. Therefore each application will store data in whatever form is most effective for its own requirements and import and export information in XBRL format so that it can be readily imported or exported in turn by other applications. In some applications, for example, the XBRL formatted information being used may be mostly tabular numeric information, hence easily manipulated in a relational database. In other applications, the XBRL information may consist of narrative document-like structures with a lot of text, so that a native XML database may be more appropriate. There is no mandatory relationship between XBRL and any particular database or other processing or storage architecture.
