In-Depth Information
schedules of doctors and nurses, sometimes the patient is not able to get answers in a timely
manner. Here, we will develop a prototype system that will answer most of the questions
that a terminal patient will have. Also, the answers from our system will be tailored to
individual patients. Ideally, our system should be able to relieve a lot of burdens from
doctors and nurses.
7.4 The evidence based reasoning software design ideas
We are going to develop a prototype of the evidence based reasoning software component.
In the following, we will outline our design ideas.
Main design ideas:
we strive the following:
1.
The component should have a Graphic User Interface (GUI) to facilitate the use of the
system. Figure 6 is a screen capture of the user interface.
2.
It should be interactive. Based on the information in the knowledge data base, it may
ask patient questions.
3.
The component should be developed in such a way that it can be used to query
different terminal illnesses, in other words, it should be generic.
4.
There should be default values for those fields that a user does not input specific
information.
5.
The knowledge database should be separated from this component for the benefit of
less coupling.

With the above design ideas in mind, we will set the boundaries and make assumptions for
the system. The following is the assumptions that we made.
