V. DATA COLLECTION
In this step only those fields were selected which were required
for data mining. The data are collected from the regular
students who had studied in BA first year. The data set used in
this study was obtained from Vikram University, Ujjain of
course B.A 2009. Our objective is to use the Examination data
of the student. The data is stored in a database: MS Excel, but it
can also be used with Oracle, Access, Interbase, any database
supporting ODBC connections and others. We have used MS
Excel because is the world's most popular database. Since the
data mining software used to generate association rules accepts
data only in arff format, we have first converted the data on Ms
Excel file into comma separated text format and then to arff
format.
