How to use ER modeling to build a local conceptual data model based on information given in a view of the enterprise; How to validate resultant conceptual model to ensure it is a true and accurate representation of a view of the enterprise Design Methodology. Structured approach that uses procedures, techniques, tools, and documentation aids to support and facilitate the process of design; Database design methodology has 3 main phases. I also learnt how to design an E-R diagram and also got a better understanding about the purposes of these diagrams during the coursework. It is about finding and Based on Middleton (2002, 39), I see the discovery, assimilation, and understanding of relationships among the items of information in the logical database design process as the creation of knowledge. The models that are based on this methodology start with the existing data structure forms, fields and reports. This is an application specific and an incomplete design methodology. The database design Database Systems” ? Similar to Middleton Internal (or machine-storage view); External (or various user views of the data); Conceptual (which “defines the entities and relationships”). I am convinced that an executable conceptual model will play an important role for the aforementioned problems: A DMBS with an entity-relationship model implements the conceptual model without an impedance mismatch. This gives a direction about how to approach database design. This database design approach is used mostly in reengineering efforts. Unfortunately, however, the conceptual data model is captured inside a database design tool that has little or no connection with the code and the relational schema used to implement the application.
