Abstract :
A general framework for solving multiple-line history queries is presented. The authors address two important historical queries in this environment: the vertical query and the horizontal query. The vertical query enables a design team to find what its design was at a past instant on its own path of evolution, while the horizontal query provides a design team with the designs of relevant teams at concurrent times in the past
