TclRAL: A Relational Algebra for Tcl

TclRAL is a "C" language extension to Tcl that provides commands to implement a formal relational algebra. This paper introduces TclRAL and describes the goals and background of the extension. Each command is described in detail and examples of a relational style of programming are given to help explain the operations that the extension provides. A comparison with other approaches is also provided.
