摘要:
A method for implementing adaptive merging in database indexes includes selecting a key range from a database query having a range predicate and searching a database for data matching the key range. The data matching the key range is merged to form a collected dataset which is stored for future retrieval. A method for optimizing B-tree representation of a database using actual queries is also provided.
