Unless you have enough knowledge of databases to connect one to OpenOffice.org (the program works with dBase and MySQL files, among others), you may want to input existing data in the form of a comma-separated value (CSV) text file. This is the simplest form of data file that is understood by the majority of office programs and databases.
