After completing this course, you will be able to
- define the three dimensions of an information model: data, process, and interaction models.
- describe he fundamental components of a Conceptual data model: entity types, relationships, and attributes.
- identify modelling entity types, relationships, and attributes.
- construct an Entity-Relationship Diagram (ERD).
- use constructs of the Relational model to aid the development of a logical data model.
- use entity hierarchies, dependencies, history, complex and recursive relationships to enhance models.
- construct solid and powerful definitions for entity types and attributes.
- model key components: functions, processes, elementary processes, events, and external objects.
- understand the purpose and process of functional decomposition
- construct an Activity Hierarchy Diagram.
- examine activity relationships through dependency analysis & document them using dependency diagrams.
- analyze the interaction between data and processes.
- develop concise and precise business specifications for elementary processes.
- construct data Flow Diagrams from Activity dependency Diagrams.
- plan, organize, and execute a modelling project.
- validate a model.
This course gives you the skills you need to develop accurate, complete models that describe business systems requirements. You will examine basic process and data Modelling concepts in detail with extensive examples to demonstrate their practical application. An essential part of developing requirements models is validating the correctness and completeness of the requirements. You'll look at how to do this through integrating the process and data models you create. This course emphasizes practical tips and techniques that speed up and enhance the effectiveness of business analysis. Progressive workshop exercises and a comprehensive, integrated case study provide you with hands-on experience as you build and test a complete business model.
Who should attend?
Business and systems analysts who are responsible for analyzing and defining business systems requirements.
You should have a general understanding of business and information technology. Prior experience in business systems analysis is not essential but will enhance your learning experience.
