Information visulization


Information visualizaion can be states as follows:

“The use of computer-supported, interactive, visual representations of abstract data to amplify cognition.”

I feel if Ptolemy did not find a way to represent a location still we don't know where we are in this world. This is a simple example which shows, to amplify our cognition there should be a stimuli.

Then information visualization is highly efficient way for the mind to directly perceive data and discover knowledge and insight from it. So lots of researches are going on this area. The reasons for that is

  • Human beings are tremendously influenced by sensory perceptions
  • The way that we learn, grow, understand, and adapt is based on our ability to view, perceive, and conceptualize thoughts and ideas
  • The power to visualize and graphically represent results, ideas, solutions, and problems in multiple dimensions, as well as to manipulate data and virtually collaborate with others, is the next big revolution in technology.
  • This will help to user to reach a decision without much effort.

These reasons may be the root course to born following Chinese proverb

“Tell me and I’ll forget…

Show me and I may remember…

Involve me and I’ll understand.”

That is why information visualization plays major role in following areas.

Medical Science,Financial Sector,Data mining,Software visualization,Geographic visualization,Forecasting,Morphological analysis,Cave Automatic Virtual Environment.

There are lot of dimensional types exist in information visualization

• Temporal
• One-dimensional (1D)
• Two-dimensional (2D)
• Three-dimensional (3D)
• Multi-dimensional (MultiD)
• Tree
• Network
• Workspace

More detail of about this dimension are available at On-line Library of information visualization Environment at http://www.otal.umd.edu/Olive/

The transaction is in doubt

Sometimes you may get this error when you use transaction scope . The transaction is in doubt I also got this error recently and able to find the reason for it.

Dead Code Problem

Problem Actually this problem occurred when i was doing integration two projects. [Phase1 and phase2 of a project] . Phase 2 is developed on top of the phase1. Parallel phase1 had changed lot . Mean time those were working on phase2 has commented existing phase 1 code without comments . Phase 1 and phase 2 merged with some conflicts. So we commented such places with the descriptive comment . After merged the result code base has merged those phase 2 commented parts. Also there was some of already dead code in phase 1. So it is difficult to understand weather this is actual dead code or commented one from phase 2. Mistake Had left dead dead code and missing comments . Lesson learned Normally developers leave dead code in their original code with the mind of future purpose. But this not a good habit to continue.As long as you use source control ,earlier code may exist. Problem will occur if you are not using such version control. In such a situation you can keep dead code with des
