Patients having different kinds of illness will go to the specific department to get treatment and medication. If required, patients are admitted in the department ward and discharged after treatment. When patients go to the department front counter, they will be registered by the staff nurses. Medical assistants will then take each patients history of illness and do a blood pressure check. The report will be sent to the doctor, and the doctor will check up their illness. Based on the treatment, specific medication is prescribed, and the patient can go home. If the patient needs to be warded for further treatment, a bed in ward will be assigned to them, and their daily progress will be monitored and recorded. After the treatment in the ward is completed, the doctor discharges the patient, and the finance department will calculate all the costs that need to be paid by the patient. REQUIRED (a) Given the case study, identify FIVE (5) main entities involved in the situation. (2.5 Marks) (b) For each of the entities, identify the primary key and TWO (2) other attributes. (7.5 Marks) (c) Using the Crow's foot notation, create a complete Entity Relationship Diagram which includes all the Primary Key, Foreign Key, Relationship and Cardinalities based on the case study. (10 Marks) 4 QUESTION 3 (50 MARKS) The Permata Minions Enterprise is a company that supplies books to most of the major bookstores in Kedah. This company also a distributor for various publishers. Established since 1999, the company was carrying on its business as supplier and distributor of books in the Northern Region of Malaysia. Its main items include various types of textbooks for schools, colleges and universities as well as other types of books for the other retail bookstores and communities nearby. The company sell both fiction and non-fiction types of books with various types of genres. Since the establishment of the company, most of its business transactions are recorded manually. Microsoft Excel has been used to record certain of their business transaction since 2011 when they first bought a computer with their cash register machine. The company have had to use the Microsoft Excel until they realised that their accounting and stock records, as well as their financial reports, will be more accurate if a new computerised accounting system can be implemented in their business. A lot of other advantages also can be gained by implementing that application. In 2019, the company appointed you as a practical student to develop a database system for the company. You are required to develop a database system using Microsoft Access. There are a few phases that need to be followed by you. Phase 1: Develop a Conceptual Design and an Entity Relationship Diagram (ERD) In this first phase, you are required to do the normalisation process based on the business documents gathered from the company. The objectives of the normalisation process are to be able to characterise the level of redundancy in a relational schema and to provide mechanisms for transforming schemas in order to remove redundancy. The first document that has been analysed by you is the company's invoice (see Figure 1). You needs to understand how the data can be stored in the database. At the same time, you need to identify the data type for each of the fields within the tables in the database. Phase 2: System Interfaces In the second stage, you are required to identify and design the forms as part of the user interfaces of the system. Based on the ERD, as well as the tables that have been created in the previous phase, you need to present the system contents and flow on how the system should work in the computerised environment. The system's interface design should be implemented in this phase. Phase 3: Queries Concurrently, while designing the system interfaces, you also need to identify some advanced form that requires you to conduct the queries using the Structured Query Languages (SQL). The invoice form, for example, requires you to run the SQL in the query section in Microsoft Access. Phase 4: Modules Some of the features in the system sometimes require you to apply basic programming codes. You are required to develop the algorithms for some of the event that occurs within the system. These codes need to be implemented in the modules section in Microsoft Access. 5 Phase 5: Establish the System Internal Controls In order to enhance the credibility of the system, you are required to establish the internal controls that should be enabled in the application, such as the user credential and input control for the specific fields. Phase 6: Reporting The backbone of the system is to produce meaningful reports for decision-makers. Thus, this phase required the student to design various types of reports that can be produced from the system, especially to be used by the managers of the company. Business documents such as invoice and receipt also need to be developed and generated from the report section in Microsoft Access.
