You are the System Analyst in the Global General Hospital, and you are assigned to design the GPS. Study and research on the case study provided in System_Development_Techniques.docx. Write a research report (with the use of diagrams or images when necessary) with words not exceeding 2500 words. In your research report, you are to satisfy the following pointers:1. Develop and submit the following UML documents based on the User Stories provideda) Use case diagramb) Use case description table based on the listed use case(Use cases are included. Both the use case diagram and description are present. The use cases accurately represent the main functions of the system including the appropriate actors. Use cases are clear and easy to understand with very few syntactic errors (diagramming errors).)c) Class diagram(Class diagram uses UML correctly to depict the classes in the right format. All classes that are needed are present, and the level of detail is acceptable. Class diagram is missing some obvious classes that should be present. Class diagram doesn’t correctly depict relationships among classes. (Missing cardinality, inheritance, etc…) Class diagram is missing many required classes, relationships, or cardinalities. Class diagram very poorly reflects the rest of the design)d) Sequence diagram(Sequence diagram is correct, has appropriate arrows which are horizontal. Correctly depicts scenario.)e) Package diagram(Package diagram is correct, has appropriate arrows which are horizontal. Correctly depicts scenario.) 2. Discuss and elaborate the System Development Life Cycle (SDLC) approach that you will adopt in developing the GPS.(provided detailed relevant explanations on how the chosen technique will be applied, what it’s good for, the advantage and disadvantage. Provided justification with supporting examples on the chosen technique.) 3. Describe how you will perform the User Acceptance Test.
