ABSTRACT
The people using an EDMS will often come to the system with little or no formal training or experience in environmental data management. In order to provide a conceptual framework on which they can build their expertise in using the system, this section provides an overview of the fundamentals of relational management of environmental data. This section starts with a discussion of the meaning and history of relational data management. This is followed by a description of breaking data apart with data normalization, and using SQL to put it back together again.
