<p>For storing data a single data file (9) or table having records of a uniform format is used. Each line in the table indicates an attribute value belonging to an object. In the lines also other information on the object and attribute value is provided such as the type of the attribute. This table format has great advantages when handling data in the table. In various processing steps (12 - 17) original data (5) in the table can be processed, thereby expanding the table by new records. The processing is made using fixed rules and rule data indicated in table shape that can easily be changed by a user who then does not have to know how different tables are linked to each other. From the produced expanded data table (9) desired information can be very easily extracted.</p> |
