Project Proposal (Marco Hille) The data set from Oracle, I want to use for my project, contains periodic sales data for video stores in several cities in the U.S. This project tries to create a visualization technique, with which one can compare the sale in time and between the different shop locations. I want to use a sinus-function to display this data. The sinus-function is periodic, the amplitude or the area under the graph can be related to the sales value of this period (month). So every period of sinus is one time period in the sales data. For every shop location, one function should be created. This allows comparison in time. By overlaying the different sinus-function for each location, a comparison between the locations is possible. Project goals: Target users are people, who want to get information from their time-periodic data. I hope to display the data in a way, that allows temporal and local comparison. The data I use is from Oracle. I want to implement my ideas with the Borland Delphi 3.0 Software. As literature source I can use the Carlis&Konstan paper.
