Reducing database fragmentation is disclosed. One embodiment includes determining whether the building of an index of data that is to be stored in a database has been initiated and determining whether the size of a sub-range of the index exceeds a predetermined size. A block of data storage space is pre-allocated contiguous to a block of data storage space allocated for the sub-range to accommodate subsequent inserts of data into the sub-range, if it is determined that the sub-range exceeds the predetermined size.
