I am a PhD student in the Department of Electrical and Computer Engineering at University of Toronto. My supervisor is Cristiana Amza. I am broadly interested in Distributed Systems and Autonomic Systems. I also look into the research happening in Operating Systems and Security from time to time.
as described on Derby's Website

Apache Derby, an Apache DB subproject, is a relational database implemented entirely in Java and available under the Apache License, Version 2.0.

Some key advantages include:

  • Derby has a small footprint -- about 2 megabytes for the base engine and embedded JDBC driver.
  • Derby is based on the Java, JDBC, and SQL standards.
  • Derby provides an embedded JDBC driver that lets you embed Derby in any Java-based solution.
  • Derby also supports the more familiar client/server mode with the Derby Network Client JDBC driver and Derby Network Server.
  • Derby is easy to install, deploy, and use.

If you're new to Derby, check out the Quick Start page.

This release contains code upto August 19, 2006 - It includes

  1. ClockProCache - my implementation of the ClockPro algorithm within in the Derby CacheManager interface
  2. PluggableCache - my attempt at a separation of the implementation and policies.
  3. Simulator - to evaluate the different cache replacement algorithms, I implemented a simulator with various algorithms
  4. Testing - to evaluate the approaches, I wrote some simple tests
