Case Study Help:
You are hired to create a software system that can quickly track the spread of epidemics in a
community. You can assume that details of any new case are immediately entered into the system.
Here is the list of features required for the application to be marketable:
1. Ability to store details about each new case
2. Ability to retrieve details about a case when the last name of the person is given.
3. Ability to retrieve details about all the cases in a given zipcode.
4. Given any zipcode and any radius, ability to quickly retrieve the list of cases within that radius.
5. Ability to store linkage between cases when such linkages are known; for example, disease
spread from A to B
6. Ability to retrieve all the cases linked to a given case.
Discuss the design of the system. Discuss how you will use different data structures and algorithms to
implement the system. You need to specify the details of the data structures such that it is evident to
the programmer how the data structures should be defined for this application. [This does not mean
you describe what a queue or stack is! Instead, you may say that you will use a sorted linked list to
store the names of all known infectious diseases.] You should also specify how each of the
Explanation / Answer
This guide examines case studies, a form of qualitative descriptive research that is used to look at individuals, a small group of participants, or a group as a whole. Researchers collect data about participants using participant and direct observations, interviews, protocols, tests, examinations of records, and collections of writing samples. Starting with a definition of the case study, the guide moves to a brief history of this research method. Using several well documented case studies, the guide then looks at applications and methods including data collection and analysis. A discussion of ways to handle validity, reliability, and generalizability follows, with special attention to case studies as they are applied to composition studies. Finally, this guide examines the strengths and weaknesses of case studies.
