Unit Code BN204
Unit Title Database  Technologies
Assessment Type Assignment 2
Term, Year T2, 2018
Assessment Title Data model development and implementation
Purpose of the assessment (with ULO Mapping) The purpose of this assignment is to develop data models and map Database System into a standard development environment to gain understanding of data model development. Then implement the data model using a commercially available database management system development tool.

On completion of this assignment students will be able to:

·         Make an informed and critical assessment of database management systems.

·         Develop data models and implement DB systems.

·         Analyse business decisions related to DB information systems.

·         Demonstrate skills in building a database application using a commercially available database management system development tool.

 

Weight 70 + 30 for the quiz

Assignment Description

 

Part A: (30 marks)

Paste below the summary of your Moodle Assignment 2 quiz.  The quiz will be open after week 8

 

Part B: (70 marks)

 

  1. Knox private Hospital contracted with GeenIT  services to develop and design their hospital database, the hospital IT Manager provided the following business rules to the GreenIT services software developer:

 

User view 1 requirement   : Patients are identified by a PatientID, and their names, addresses, and ages must be recorded.

 

User view 2 requirement   : Doctors are identified by a DoctorID.  For each doctor, the name, specialty, and years of experience must be recorded.

 

User view 3 requirement   : Every patient has a primary physician/doctor. Every doctor has at least one patient.

 

User view 4 requirement   : Doctors prescribe drugs for patients. A doctor could prescribe one or more drugs for several patients, and a patient could obtain prescriptions from several doctors.  Each prescription can have more than one drug.

 

User view 5 requirement:  For each drug, identified by DrugID and the trade name and formula must be recorded.

 

User view 6 requirement: Each pharmacy sells several drugs and has a price for each. A drug could be sold at several pharmacies, and the price could vary from one pharmacy to another.

 

User view 7 requirement: Each pharmacy has a unique name, address, and phone number.

 

Complete the information-level design for the database that satisfies the above constraints and user view requirements. In order to complete this information-level design you are required to answer questions given below 1(a) – (f).

1.

  1. Analyse the all user requirements given above, identify and list all entities described in all user requirement.

(5 Marks)

 

  1. Add attributes to these entities and represent these entities (or Tables) and attributes as a collection of Tables and attributes. You are required to arrange them as given in the example below.                                                                                                                         (10 Marks)

NB: Select suitable primary key for each table and underline them.

         Eg.     Patient (PatientID, name,…….)

  1. Outline at least 2 relationships between those                                                          (5 Marks)

Eg. Every patient has a primary physician/doctor. – One-to-many.

 

  1. Determine the functional dependences.                 (10 Marks)

Eg.   PatientID à name, address, age, ……

 

  1. Normalise the tables.                 (10 Marks)

 

 

  1. Represent the structure of your database visually by using the entity-relationship (E-R) diagram. If you make any assumptions about data that are not explicitly given in the problem, these must be described. You need to use Visio or any other software tool to create the ER diagram.                                     (15 Marks)

 

  1. Build this model using MS Access by creating these tables and Relationships in Access. Populate these tables with appropriate data, at least 2 records in each table.  Include following into your MS Word document.

 

  1. Relationship diagram created in Access. (Select database tools àRelationships in the Access menu)

 

  1. Data sheet view and design view of your tables. Eg.

Figure 1 Data Sheet view

Figure 2 Design View

(5 marks x 2 =10 Marks)

 

  1. Give one example for the type of report that can be obtained from this “Knox private” database.

(5 Marks)
