The present disclosure relates to a method for hash collision detection based on the sorting unit of the bucket designed to reduce the future search time by pre-aligning the database in the bucket and to enhance the efficiency in a search within the database. The present disclosure, a method for hash collision detection based on the sorting unit of the bucket using conventional separate chaining method, comprises aligning records in a single bucket of a directory in ascending order or descending order and maintaining the alignment of records in the bucket when new records are added to the directory.

The present application relates to a heap sorting method based on arrangement and apparatus which can improve the heap sorting conducting speed through reducing access (I/O) frequency of the external memory when conducting heap sorting through storing binary data in the basic access unit of the external memory device in reference to the subtree unit.

Method and device of heap sorting based on a memory device

A Database method for a B+ tree based on a PRAM. The database method divides each node into two areas, areaand area. A key value is inserted/retrieved/deleted for the each node. Inserting the key value requires firstly inserting a new key value to areaif areain the node is not in a full state. Retrieving the key value requires identifying whether the node is a leaf node. If the node is a leaf node, the key value is retrieved from areaand areasequentially. Deleting the key value requires merging areaand areain the node, and deleting the key value in the merged node. The method enhances durability and data processing capability.
