Process Modeling, Er Diagram and Logical Data Modeling

Good Essays

White paper on Process Modeling, ER diagram and Logical Data Modeling Authors Yogini Wagh Process Modeling Process modeling is the concise description of the total variation in one quantity, by partitioning it into a deterministic component given by a mathematical function of one or more other quantities, plus a random component that follows a particular probability distribution. Software process modeling and business process modeling are the techniques for obtaining a better understanding of business processes. In other terms, it is a model of one or more business processes, and defines the ways in which operations are carried out to accomplish the intended objectives of an organization. It can describe the workflow or …show more content…

There are several notations for data modeling. The actual model is frequently called "Entity relationship model", because it depicts data in terms of the entities and relationships described in the data. Several techniques have been developed for the design of data models. While these methodologies guide data modelers in their work, two different people using the same methodology will often come up with very different results. Most notable data models are: ▪ Bachman diagrams ▪ Entity-relationship model ▪ Object-relational mapping ▪ Object Role Modeling ▪ Relational Model References: 1.
