Welcome

Welcome! This site contains links to material relevant to my professional life. I'm the author of AI, Quantum Computing and Web3 and eight other technical books. I've been involved in Information Technology since the early 1980s and have experience with Database and Web3 technologies.

I founded ProvenDB - a blockchain database - and held executive positions at Quest Software and Dell.

As well as AI, Quantum Computing and Web3, I'm the author of CockroachDB Definitive Guide, MongoDB Performance Tuning, Architecting Distributed Transactional Applications, Next Generation Databases,  Oracle Performance Survival Guide, MySql Stored Procedure Programming (with Steven Feuerstein), Oracle SQL High Performance Tuning, as well as contributing to several other books on database technology. I write monthly columns at Database Trends and Applications and more occasional articles elsewhere. 

I can be contacted by email at guy.a.harrison@gmail.com. 

I live in Melbourne Australia with my wife Jenny in beautiful Kingsville.    Our adult children Chris, Kate, Emily, Sean, Erin and Michael and their partners, dogs, cats and killer rabbits live nearby. 

In my spare time I hike, write and study astrophysics.
