The need for analyzing huge amount of data in organizations as well as effects of analyses results on its decision making and strategic planning in growing. Multi-dimensional databases issue this problem. Multi-dimensional conceptual model strongly affects multi-dimensional database development. Many of the existing multi-dimensional models are based on traditional relational model while some others aim to organize data using a multi-dimensional perspective. These models do not support heterogeneous dimensions and this is a major deficit, causing limitations in their applications. In this paper, a conceptual model is proposed to be able to model heterogeneous dimensions. The concept of summarizable hierarchy proposed and is used to model heterogeneous dimensions in multi-dimensional databases. The proposed model is shown to be more suitable for modeling real-world applications. |
