An introduction to Natto        
and it's unique concept.

What's Natto?

Natto is a software for data analysis, with a concept of "visible, touchable and comprehensible". You can easilly extract valuable informations from your dataset by mouse-driven functions, without almost any expert knowledge.


Concept

   Visible
The visual representation of datasets helps you to find underlying structure behind the data.
   Touchable
You can "touch" your data by intuitive mouse operation to analyze the data interactively.
   Comprehensible
Simple, but powerful analysis tools are available. You can easilly extract valuable informations with minimum knowledge of data analysis and operation of the software.


Backgrounds

Analyzing accumulated data to extract valuable informations — The methodologies of data analysis has been developed dramatically over the last centry. According to the massive development of computer sciences, the trend of data analysis has been changed from classical mathematical statistics to data mining. This drastic change made it possible to apply data analysis methodologies to common problems in not only science but only business, and has brought great results in many fields such as marketing.

However on the other hand, highly technical knowledge is required to conduct effective analysis accurately. In addition even for skilled specialists, it requires quite time-consuming tasks to figure out the underlying structure behind data appropreately.

Natto has been developed to provide a solution to this problem. Data is visually represented as graphs, and you can figure out the entire picture of the data by intuitive mouse operations. Simple but powerful analysis tools help you to extract valuable informations in detail.

Natto supports quick and appropriate understandings of data, and quick decision making. Make use of this new tool for data analysis for your business and research.
