The SQLEDDI environment
Studying the design and implementation of SQL
This project provides an extension to the tkeden
environment in which it is possible to study the use of SQL in conjunction
with EDDI, a definitive notation based on relational algebra, as a
relational database query language.
sqleddiWard2003 is much the same as sqleddiBeynon2002 - see that
project for further details about the history of this project.
sqleddiWard2003 was produced in order to clarify parts of sqleddi
operation for the paper "A Computer-Based Environment For The Study Of
Relational Query Languages" by Beynon, Bhalerao, Roe, Ward for
Teaching, Learning and Assessment in Databases LTSN workshop. The
paper is included in the Presentation directory.
In this version of sqleddi, a new Uneddifying Interface has been
added. Additionally, the multiple Run.eden files have been simplified
to just one. %toysql is now available on executing installtoysql();
Also included here is the presentation (written in Eden) used at the
Databases workshop. [Ash]
