Abstract
In some examples there is disclosed a computer-implemented method comprising providing an upper index having derived values corresponding to unique key values contained in a columnstore used to store at least part of a database. It may then be determined whether there is a duplicate in the database of the unique key value of the data to be written by querying the upper index for the unique key value and, in response to the upper index having a duplicate derived value, identifying a lower index and a position within the lower index, wherein the lower index is associated with at least part of a column of the columnstore, and querying the lower index to determine whether a unique key value corresponding to the position matches the unique key value of the data to be written.
