Abstract (en)
[origin: WO9938094A1] A database file management system for accessing data records is being executed on data processing system, the data records are linked to a trie index that is arranged in blocks (402, 405, 406 and 407) and being stored in a storage medium. The trie index (A, B and I, element 402) enables accessing or updating the data records by key or keys and being susceptible to an unbalanced structure of blocks. There is provided a method for constructing a layered index arranged in blocks, which includes the steps of providing the trie index and constructing a representative index over the representative keys of the trie index. The layered index enables accessing or updating the data records by key or keys and it constitutes a balanced structure of blocks.
