Logical Data Modeling also known as Entity/Relationship (E-R) Modeling is a key method for getting a handle on the data requirements of an organization. Logical data models provide a database independent solution to data requirements which then can be driven forward to become effective database designs.
This online training course covers the concepts and notation of logical data modeling and shows the steps needed to create and extend logical data models. Many exercises and examples are included to enhance learning.
In addition, the course goes beyond these fundamentals. The situation where a new data model must be created from scratch is one of many situations, so this course shows how to handle other situations such as: building from industry or canonical data models; extending legacy data models; and extending software package data models. In addition, data model patterns will be introduced such as: history and audit modeling, multi-business unit modeling, codes and reference data, and user defined attributes. Understanding these situations and patterns, is critical to success in data modeling.
