In this context, this paper describes an OO conceptual modeling approach (based on a subset of UML) to address the above-mentioned issues. Thus, the structure of the system is specified by a class diagram, and from then, we define

Ray Forrest,Sin Yee Koh,Bart Wissink has strong relation with mathematics by applying a new defined concept, i.e. .. Afterwards, the mathematic soundness provides a foundation to handle natural hierarchical relationships among data elements within dimensions with many levels of complexity in their structures. Hereafter, the multidimen

Difficulties often arise in producing familiar, complete and consistent sample data on any scale. Producing sample data manually often causes problems that can be avoided by an automatic

It is also shown that this concept can unify the commands for data definition and data manipulation in query languages, thus generating tight envir

The validity and precision of proposed solution is verified by extensive simulation on three substantially different data files. The precision of obtained

The algorithm has been implemented, and we report on issues arising from this implementation including optimization techniques incorporated.
