摘要：
A data warehouse mainly deals with historical data and specialized retrieval. In this research we classify historical data and present scheme for their efficient handling. Our classification of historical data is based on their inherent properties and frequency of their use, which involves time. We have used a mufti-dimensional Grid file organization for storing and supporting efficient management of historical data. We have defined operations such as merge, split, reorganize, etc., which are essential for managing the storage organization. The dynamic nature of the mufti-dimensional grid file is used to identify and archive stale data and to optimize storage usage.
