Abstract(in Japanese) (See Japanese page)
Abstract(in English) SuperSQL is the extended language of SQL which made it possible to structurize the output result from a relational database, and to specify various layout expression, however, some layout cause a output result that lost a part of information on the target database of the query, and it may not be expressed appropriately. Then, this research defines the concent of information capacity and the classification of the output result based on the size relation between the information capacity of a database and the information capacity of a query. Moreover, We proposed and realized the tequnique of judging the existence of the abnormalities in a result output by computing the information capacities of a query and a database at the time of SuperSQL query creation, and measuring both the calculated information capacity.
