Assignment title Hospital Information System-HIS
Purpose of this assignment
To provide learners with the knowledge and skills needed to understand, design, query and implement database systems.
Company/Scenario:
You belong to a team of Database developers, who have been assigned to develop a database system for Hospital Information System (HIS), the database should contain the following:
a. Patient information like names, addresses, Unique Patient Numbers (UPN), Patient Medical History (PMH), the database could contain other patient information that may be deemed necessary.
The Patient Medical History (PMH) should contain among others the following relevant information regarding a patient; hospital admission and discharge date, reason of admission, blood group, the room and ward the patient stayed and the type of operation a patient undergo during the hospital visit.
b. The information of hospital staff like names addresses, employment dates, telephone numbers, Salaries among others must be included. The hospital staff that should be in the HIS is limited to Surgeons and Nurses.
c. The Surgeons are classified as Surgeons and Senior Surgeon called consultants, who supervises Surgeons during operation on any patient, but could also carry out some Surgeon role.
d. The Hospital Information System (HIS) must include wards, each ward is assign to a supervisory nurse, also each ward have been named according to the type of care like gynaecology, geriatric , paediatric, orthopaedic. These wards are made up of rooms with unique numbers.
The above specifications was obtained by your team during the requirement analysis stage of the SDLC, as was expected, this specifications might not be complete because it was given to your team by none IT experts, thus lots of reasonable and creative assumptions is expected from your team when developing the database.
[The above scenario is a basic guide, creative imagination and sensible assumptions is encouraged and will be awarded the maximum marks]
Task 1 : (LO1: 1.1, 1.2, 1.3 and M1) interim deadline (10/05/15) Word Limit (500-900)
Task 2 (LO2: 2.1, 2.2, 2.3 and D1 ) interim deadline (24/05/15) Word Limit (350-600) (Formative Assessment in Week 3)

Task3(LO3: 3.1,3.2,3.3,M2 and D2) interim deadline (07/06/15) Word Limit (450-850)
(Formative Assessment in Week 5)

Task 4 (LO4: 4.1) interim deadline (14/06/15) Word Limit (450-550)
Task 5 (LO4: 4.2, 4.3 and M3) interim deadline (21/06/15) Word Limit (350-650) (Formative Assessment in Week 7)
Task 6 (LO4: 4.4, 4.5 and D3) interim deadline (28/06/15) Word Limit (250-550) (Formative Assessment in Week 9)

Evidence checklist Summary of evidence required by student

M1: Detailed explanation of the approach used and how is mapped to System Development Life Cycle (SDLC)?

D1:Evaluate the process involved
in the design of the “Hospital Information Database ” system by producing a complete Entity Relationship Diagram (ERD) on top”, you should use a specific notations (eg Crow foot or Chen’s)

M2: . Critically evaluate how meaningful data has been extracted through the use of query tools: To earn this score, the learner have to show if meaning full data was extracted from the designed database, or an appropriate explanations given why no meaningful data was not extracted.
D2: Ability to use more intensive querying like the following:
i. Group functions
ii. Sub-queries.
iii. others.
Must be shown by the learner.

M3: A statutory documentation for the database system must be produced: is a combinations of all the documents produced in task 5 D3: Critically discuss about the functionality, reliability, consistency and performance of your designed system.
