A universal way to design and build exam questions' bank

摘要

The traditional exam questions' bank is designed and built by one traditional/unconstructive way, which means every kind of exam question has its unique scheme to store and handle. This way is easy to design, but hard to handle when more and more different kinds of exam questions are put into the bank. So we can use document as a kind of container to store exam question, which changes the basic storage structure of exam question item. If we put exam questions into document container, we can get a common interface at system level to access those questions without considering the detailed structures of different kinds of questions. Anyway, it's not so straightforward to access those question items in containers, but we can use some technologies to make it easy, such as OLE IB. Finally, in this context, an application system is introduced which is designed and built by this kind of universal way.
