  • I As a user interacts with a database or expert system, s/he may reveal a misconception about the objects modeled by the system. This paper discusses the R O M P E R system for responding to such misconceptions in a domain independent and context sensitive fashion. R O M P E R reasons about possible sources of the misconception. It operates on a model of the user and generates a cooperative response based on this reasoning. The process is made context sensitive by augmenting the user model with a new notion of object perspective which highlights certain...

  • Some features of a real world situation can be difficult to model using only the features of the E-R model that we have seen so far. • Some quite common concepts require extending the E-R model to incorporate mechanisms for modeling these features. Again, we won’t look at all of them, but rather an overview of some of the more important extensions.

  • System R itself was never produced commercially, but directly led to the development of SQL/DS (1981 running under DOS/VE OS, a VM version followed in 1982) which was IBM’s first commercial relational DBMS. • IBM however, did not produce the first commercial implementation of a relational DBMS. That honor went to Oracle (Relational Software) in 1979. • Today, the relational DBMS system of virtually all vendors is based on SQL. • Each vendor provides all the standard features of SQL. Most vendors also provide additional features of their own, called extensions to standard SQL.

  • As already stated, a road vehicle on pneumatic tires cannot maintain a given trajectory under the effect of external perturbations unless managed by some control device, which is usually a human driver. Its stability solely involves such state variables as the sideslip angle β and the yaw velocity r. In the case of two-wheeled vehicles the capsize motion is intrinsically unstable forcing the driver not only to control the trajectory but stabilize the vehicle. A possible scheme of the vehicle-driver system is shown in Fig. 27.1.
