Since the bulk of the database processing is done on the back-end, the speed of the DBMS isn't tied to the speed of the(31).The major disadvantage of Client/Server system is the increased cost of(32) and support personnel who maintain the database server. There is also the issue of(33)with so many parts comprising the entire C/S system; Murphy's Law can kick in-the more pieces that compose the system, the more pieces that can fail. It's also harder to track down problems when the system(34). And it can initially take longer to get all the components set up and working together. All this is compounded by the general lack of experience and expertise of potential support personnel and programmers, due to the relative newness of the technology. As C/S system become more common, this problem should abate.Therefore the C/S system is more(35).

was characterized by tools such as prolog and OPS. prolog is a simple backward-chaining environment, and OPS is a simple forward-chaining environment. This led to the second generation of knowledge-engineering environments. Its goal was to model, prototype and construct(117)systems.All three generations were oriented toward generic(118)and represented generalized implementation environments for the construction of expert systems. knowledge bases and AI applications.Some of the solution-oriented products are also seamlessly integrated with generic knowledge-engineering environments, permitting end users to add(119) rules and objects, as well as predefined knowledge-based logic to address problems in manufacturing simulation.Marketplace orientation is rapidly(120)toward solution-oriented intelligent product environments. the fourth generation represents a new line of thinking and ' develop-merit by commercial fu-ms. will reduce the cost risk and development time associated with problem solving.
