Definition: An area of storage where items with a common property are stored. Typically tree data structures and sort algorithms use many buckets, one for each group of items. Usually buckets are kept on disk.
Generalization (I am a kind of ...)
Aggregate parent (I am a part of or used in ...)
radix sort, bucket sort, elastic-bucket trie, hash heap, extendible hashing.
Note: A bucket is used when a number of items need to be kept together, but the order among them is not important. Conceptually it is a bag (rather than a set).
