Course Overview

Logical Data Modeling explores business rules, policies and procedures and how they can be modeled effectively. Participants will learn entity relationship diagramming, super and sub-types, attributive and associative entities, and documenting data constraints. The logical data modeling approaches taught in this engagement are designed to focus the attention on the important requirements of the business that are discovered through significant user involvement during the analysis phase. Participants will also learn how to create models without being limited by technology or organizational structure. It also provides an understanding of how the data elements are constructed, allowing for an integrated and seamless transition between the work of the BA and the data architect. The ability to communicate the intersection of business processes and information/data needs is key to the success of any software development project. Understanding and explaining user needs is a major challenge and opportunity for the business analyst. The business analyst who understands structured modeling has a distinct advantage in addressing and communicating requirements. And the use of models can greatly increase all stakeholders’ understanding of the relevancy of business rules and data management requirements to the project at hand. This engagement is replete with case studies and scenario and even a role play to aid absolute understanding and help with the retention of subject as well as help you understand complex elements with ease.
