Scheme for automatic data conversion definition generation according to data feature in visual multidimensional data analysis tool

摘要

A scheme for automatic data conversion definition generation based on data feature such as a decision tree or a statistical feature, so as to enable a quick data analysis in a visual multidimensional data analysis tool. In an apparatus for converting data stored in database or files into graphic data according to the data conversion definition and displaying the graphic data, a definition generation assistance device for automatically generating the data conversion definition is provided, where the definition generation assistance device extracts a data feature of the data from a scheme and contents of the database or files, and automatically generates the data conversion definition according to the extracted data feature, the data conversion definition being formed by an attribute mapping definition defining combinations of data attributes and graphic data parameters and a data conversion method definition defining a method for converting a value of each data attribute into a value of a corresponding graphic data parameter. <IMAGE>
