Abstract
Array DBMSs extend the set of supported data structures in databases with (potentially large) multi-dimensional arrays. This information category actually comprises a core data structure in many scientific applications.
When it comes to Petabyte archives, storage costs prohibit importing (i.e., copying) such data into a database. Therefore, in-situ processing of database queries is required, that is: evaluating queries on the original files, without previous insertion into the database. We have implemented such an in-situ feature for the rasdaman Array DBMS. In this demonstration, we show with rasdaman how query processing in array databases can simultaneously rely on arrays stored in the database — as usual — and in operating system files, like preexisting archives.
