Title
4DIS: a temporal framework for unifying meta-data and data evolution
Abstract
Time is all important aspect of all rval-world phenomena. Events occur at specific poims in time: objects and their relationships exist and change over ',ime. "[radii iomdly, temporal database systems allow different snapshots of data units to be modeted and queried, ltowever, it has been quite difficult to model evolution of meta-data: this is primarily due to the lack of proper logical data independence supporI in existing database systems. In this paper, we introduce a temporal object database model called Four Dimensional Information Space (,{DIS). [n 4DIS, both recta-data and data Ulfits are modeled uniformly as objects. The databa~se is modeled as a set of relationships, each of which relates two individual objects. Each relation is also ~ussociated with a temporal dimension which supports valid and transaction time. This allows time to be naturally integrated with objects of arbitrary granularity and provides flexible logical data independence support for the database. Meta-data aud data evolution could thus be unified in a standard framework. "I~mporal operations can also be evaluated against both recta-data and data units in a uniform maturer.
