Many organisational DSpace users run reports on DSpace not from within DSpace itself, but from within an external reporting system (Business Intelligence, JasperReports, etc) which connect to the DSpace database via ODBC. Reports may be run on an external reporting system rather than DSpace to allow integrated reporting across a number of systems, to allow integration with other organisational systems, to exploit existing reporting skills, or for other reasons. Typically the connection is read-only, this allows both better security (since it limits the damage that an incompetent or malicious user can do) and better performance (since read-only accesses to tables typically require less locking or resource-use in most databases).

Creating reports

ODBC-based reporting tools work by running one or more SQL query against the underlying DSpace database. You can find some examples in

which illustrate the kinds of SQL joins that you'll be looking at using. Note the use of item.in_archive = 't' and item.withdrawn = 'f' to check whether the item has been deleted or withdrawn respectively. A diagram of the DSpace database schema is included in the Storage Layer section of the DSpace documentation. The SQL itself is stored in database-specific subdirectories of https://github.com/DSpace/DSpace/tree/master/dspace/etc
