The database controller configured to store an ordered list comprising, for each of the data items individually, the identifying information of the storage unit upon which the data item is stored. The database controller configured to maintain a frequency record, recording the values of prefix portions of the data items and the number of data items having each prefix portion. Wherein, the ordered list and the frequency record are ordered by applying the same ordering metric to the prefix portions. The database controller being configured to receive a range query specifying a search prefix portion, to use the frequency record to calculate where to find in the ordered list the identifying information of storage units storing the data items having the search prefix, and using that identifying information to retrieve query results."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Database controller, method, and program for handling range queries","description":"A database controller for a database of data items distributed across a plurality of storage units.
