Data Modeling and Analysis

Welcome to the Data Modeling and Analysis course, where you’ll explore the fundamental concepts and techniques for modeling and analyzing data. These skills are essential for designing systems that are both effective and efficient.

 

In this module, you’ll gain a foundational understanding of data modeling and its importance in systems analysis, learn how to create and interpret Entity-Relationship Diagrams (ERDs), and understand how Data Flow Diagrams (DFDs) represent the flow of information within a system.

 

Data Flow Diagrams (DFDs) are powerful graphical tools used in system analysis and design to illustrate how data is processed within a system, showcasing its inputs and outputs. They provide a clear visualization of information flow, enabling a comprehensive understanding of data movement and transformations across an organization. This exercise will guide you through the practical application of DFDs in a real-world scenario.

 

Objective: To apply Data Flow Diagram concepts to effectively model and analyze data flow and processes within a complex system.
