Conceptual Data Modeling – Resisting the Urge to go Physical
Objectives
The objectives of the course are to:
- Understand what a Conceptual Data Model is and how it is used
- Understand the problems caused by foregoing Conceptual Data Modeling
- Understand how Conceptual Data Models will improve data and information quality and improve project success
- Learn how to develop CDM’s
- Learn how to use CDM’s to understand business requirements and validate understanding with the business
You will:
- Analyze a real-life example of a problematic data model and understand the impact of not identifying proper relationships and cardinality
- Learn how a Conceptual Data Models differs from other types of data models
- Understand best practices for a phased modeling approach
- Learn a common modeling notation and develop CDM’s for a class exercise in a small team environment
- Learn how to utilize CDM’s to validate business understanding and to develop downstream logical and physical models
- Learn about the different types of Conceptual Data Models
- Learn why an Enterprise Conceptual Data Model is a critical enabler of enterprise-wide endeavors, e.g. data governance and stewardship, ERP, SOA, DW/BI, etc.
