Abstract: Spatial relations and Integrity constraints are key components of topographical databases which have been used for the development of efficient models. Efforts have been made on formal definitions of spatial relations with the 4-intersection model (4IM) and 9 – intersection model (9IM), which are significant components in designing any model in topographical databases. Earlier definitions were also used for this model with required better modifications. This paper introduces new integrity constraint rules and semantic constraint rules which are used to design the model. The main contribution of this paper is to implement Conceptual frameworks for constraint rules for efficient and effective topographical database management.
