Information in computer memory system maintaining

摘要

The method involves organising the information in a first memory as a data structure, that has a hierarchical ordering in which the information is organised in a hierarchical structure comprising a number of levels including a bottom level and a top level. The data is then chronologically stored in a second memory in which the information is written into the second memory in a chronological sequence from the bottom level to the top level for creating a database (160). In the database data and index records of a tree (200) are chronologically written to the media (400) in bottom-first/top-last order. The bottom level data nodes (230) are written, time wise, before the intermediate-level index nodes (220) which point to them. The top level root node (210) is written last. The time wise sequencing of the data is reflected in the left-to-right ordering of the nodes.
