Data modeling has many purposes in information management including analysis, design, documentation, and standardization. But it is first and foremost a visual language used to describe and communicate about data. Every information management professional needs to have at least a basic understanding of data modeling, as do many who work with them. Operating without this knowledge is much like traveling in a foreign land without understanding the language – it seriously inhibits your ability to comprehend, to contribute, to participate, and to enjoy the experience. This course is designed to provide the fundamental understanding of data modeling that is necessary to travel in the land of information management.

- have an appreciation for three levels of data modeling – conceptual, logical, and physical – and know where and when each is used

- be able to find the business meaning and business rules that are represented in data models
- understand the terms entity, attribute, and relationship well enough to describe the role of each in data models
- understand the nature of identifiers and keys and describe their role and purpose in database navigation
