Traumwind - how does one represent hierarchical data in a relational database?

Relational Modeling of Biological Data: Trees and Graphs. Many bioinformatic data sources represent information in hierarchies. But how does one represent hierarchical data in a relational database? And, more importantly, how can one make efficient use of such data? Aaron Mackey looks at these issues and shows you how to build and manage a relational database that supports hierarchical data.
