Unifying Modeling Language-Merise Integration Approach for Software Design

Software design is the most crucial step in the software development process that is why it must be given a good care. Software designers must go through many modeling steps to end up with a good design that will allow for a smooth development process later. For this, designers usually have to choose between two main modeling methodologies: Merise and UML. Both methodologies are widely used; however, each one has its own advantages and disadvantages. This paper combines both techniques and merges their advantages to come up with an approach that would help software designers make the best of both methodologies. This integration mainly targets the software design step in general but can be specifically applied to database design. It presents the weaknesses and strengths of each one of UML and Merise as two techniques used in database modeling and design. Later in this paper, a comparing of UML and Merise diagrams is lead and based on it, the decision on which of the two is the best at each step of the modeling process.
