Pythian is pleased to announce our speaking schedule at this year’s Oracle Open World 2012! Here are the speaking sessions that we will be participating in, including one session that we will be co-presenting with our friends at Harvard Business Publishing.
This Australian conference represents the climax of Technology, Development and Applications users in one go. As icing on the cake, mobile technology and telecommunication will also feature during this scintillating saga of expertise and sharing of knowledge. Where there is mentionable database talk, there is Pythian. I will be presenting two sessions at the Insync12 this year, both about Exadata, a technology closer to my heart.
