Extending SQL for Decision Support Applications - CEUR
... The challenge of extending database systems for decision support applications has been the topic of much recent research—a very incomplete list of previous work includes [11, 8, 12, 4, 10, 5]. Yet, there is no generally accepted solution for the problem, which remains a critical one, since the inabi ...
