This site contains links to material relevent to my professional life. I'm an IT professional with experience in a range of disciplines and technologies but probably best known for my involvement in relational databases such as Oracle and MySql and for my writings on emerging database technologies such as MongDB, Cassandra and Hadoop.  

I'm CTO of Southbank Software and a partner at Toba Capital 

I'm the author of Next Generation Databases,  Oracle Performance Survival Guide, MySql Stored Procedure Programming (with Steven Feuerstein), Oracle SQL High Performance Tuning and Oracle Desk Reference, as well as contributing to several other books on database technology. I write a monthly columns at Database Trends and Applications and more occasional articles elsewhere. 

I'm an Oracle ACE and a MongoDB certified DBA and developer. 

My blog contains occasional contributions of a technical nature and I can be contacted by email either at  I'm @guyharrison on twitter.

I live in Melbourne Australia with my partner Jenny, daughter Emily, one dog and 1-2 cats in beautiful Yarraville.    My adult children Chris, Kate and Michael and their partners, dogs, cats and killer rabbits live nearby. 

In my spare time I worry about what on earth I'd do if I ever had any spare time.
