JRS (Java Relational System) is a relational DBMS implemented in Java and designed for educational use
The project was coordinated by Antonio Albano and the software was developed by the following dedicated students:
The swing interface and the browser were implemented by Renzo Orsini. The representation of a query plan in the form of a tree was implemented by Luca Saiu. Their effort and cooperation in bringing JRS to life are much appreciated.
The choice of Java was made to simplify the implementation by several students and to have an easier-to-update and portable system.
JRS has been developed in conjunction with the text Costruire sistemi per basi di dati (available in English: Relational DBMS Internals) by Antonio Albano. The HTML documentation provides an overview of the system architecture and component interfaces. The text provides the necessary background on file organizations, buffer management, access methods, relational query languages and operator implementation techniques, query optimization, concurrency control and recovery.
JRS was inspired by similar projects made in C++ first by DeWitt and Jussi Myllymaki (Minirel) and then by Mike Carey and Raghu Ramakrishnan (Minibase) at Wisconsin University.
