Gong Show2 Things to Work On

Stan Zdonik

#1: Interactive Viz

• Visualization is good.– Witness products like Visionary (2D).

• 3D is better.– The cave– VR-based data warehouse

• Interaction is the future.– e.g., dynamically switch views

– stretch dimensions– aggregate differently

The Problem

• Multiple SP2’s rendering what you see.– Terrabytes on disk backing the scene.

• Fetch data in response to gestures with almost no delay.

• Approach: intelligent data staging– Needs a model of the user

• Other examples:– War game simulations– Distributed gaming (e.g., Quake)– Telepresence

#2 Distributed Databases

• SDD-1 (& ?) had the model right.– Distribution and replication are transparent.

• Back then, the network was very slow.• Today, bandwidth is plentiful.

– Moving data is not a big issue– Synching is cheap.

…but more than just relations

• Today I have:docs on my laptopsdocs on my desktopsdocs on the department’s file severdocs on my PDA

• I want ALL my information to appear in one big unified space (no visible copies)

• It’s time to try again!!

tons of copies
