STREAMING METATREE DATA STRUCTURE FOR INDEXING INFORMATION IN A DATA BASE |
摘要 |
A streaming metatree data storage structure in which each data item (40) is stored as a procession of nodes (52) and where data units common to more than one data item (40) are stored only once. The nodes (52) are stored in a logically linear fashion, or stream, and information (62) within a node (52) indicates its relationship to the other nodes and within the tree hierarchy. The data structure provides a mechanism for distributing the nodes (52) among multiple physical memory blocks (80) and for traversing backwards through the tree. Data items are added by creating a temporary tree for new items until it becomes too large, and then merging the temporary tree into the main tree.
