摘要
In a database file management system for accessing data records and being executed on data processing system. The data records are linked to a trie index that is arranged in blocks and being stored in a storage medium. The trie index 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.
