Abstract

We propose a technique for estimating the back-end size based on its complexity of business software using ER diagram artifacts. Our size estimation is based on the structural complexity of ER diagram which includes the concepts of generalization/specialization, and aggregation as well as the semantic integrity constraints identified during conceptual design phase. We proposed size metrics for measuring entity size, relationship size and semantic integrity constraints size and finally the effort of development has been estimated using COCOMO model.
