Data SalaMining
===============
About
Data SalaMining is a visualization tool, wich gives a 3-dimensional look
on large chunks of data. With DSM it is possible to look at several
attributes in respect to there development over time.

This software was developed at the Otto-von-Guericke University,
Magdeburg.
The Data SalaMining software is published as open source software and
freeware.
System Requirements
- graphic card with OpenGL support
- OpenGL and GLUT installed
- Qt 2.3 or higher
Usage
You can either open an existing data file by using the file dialog,
or you can get random data by cancelling the dialog.
Use the arrow keys throughout the application:
- left/right ... change the current entry
- up/down ...... change the active attribute\n\n"
Legend:
Choose the active attribute and look up their full names.
Star Diagram:
With convectional star diagram you can examine the quality of one entry.
Larger area is better. Click and drag the pointer to rotate the diagram
and switch to another active attribute.
Area Diagram:
Determine the development of one attribute over time.
Click and drag the pointer to change the active entry.
DSM or "the cylinder":
This is the new way of looking at star diagrams in respect to their
development over time. The concept of connecting the points to a area in
the conventional star diagram is picked up. Whereas in the new way not
only those points are connected to polygons but to a cylinder-like
object where the different polygons of each entries are connected with
each other. Now it is possible to see whether a set of entries is
decreasing or increasing in quality over time. The thicker or more
cylinder like the better. This frame features mouse interaction to
change the current entry (left mouse button) and active attribute (right
mouse button).
Slider:
This special slider gives you the possibility to alter the size of the
selection by moving the triangles or move the selection by using the
body of the slider.
Color Menu:
Change the color of the cut or the data by using a color picker.
File Format:
If you want to use your own data to be visualized, you have to create
a semicolon-seperated text-file with the following structure:
entry;attribute1;attr1;...;attributen;attrn;
0001;0.512;...;1.0;
0002;0.121;...;0.15;
...
The first line has the names of the attributes and their abbreviations.
The following lines start with an entry number and the values which
have to be between 0 and 1.
For implementation details consult the documentation file.
