Assignment 01
Important Points:
- Carefully check carefully the hand in date and the instructions given with the assignment. Late submissions will not be accepted.
- Ensure that sufficient time is spent to complete the assignment by the due date.
- Do not wait till the last minute to print or bind the assignment. Such excuses will not be accepted for late submissions.
- You must be responsible for efficient management of your time.
- If you are unable to hand in your assignment on time and have valid reasons such as illness, you may apply (in writing) for an extension.
- Failure to achieve at least a PASS grade will result in a REFERRAL grade.
- Non-submission of work without valid reasons will lead to an automatic REFERRAL. You will then be asked to complete an alternative assignment.
- If you use other people’s work or ideas in your assignment, it must be properly referenced, using the HARVARD referencing system, in your text or any bibliography. Otherwise, you’ll be found guilty of committing plagiarism.
- If you are caught plagiarising, your grade will be reduced to a REFERRAL or at worst, you could be excluded from the course.

*Please note that assignment guidance is for reference only and should be more specific in detail to meet customized needs. Assignment brief Case study You are employed as a Database Developer for a large IT development company. The company has been approached by a transport company called SmartMovers which has grown to a level where need to have an automated system to handle day today operational activities to meet customer demands. You are given the job to design and develop a database solution for SmartMovers to meet their business requirements. The company transports chemical products from one location to another on behalf of registered customers. Customers are of three types namely Catogory1, 2 and 3. Each customer is given a unique customer number and his or her details have to be recorded in the system. Each transport operation is called a job, which involves picking up one or more loads of the products from a customer requested start location and delivers it to a customer requested destination. A unique number is given for each job and for each load when they are created. A Load is transported using a particular transport unit, which consists of a lorry, a driver, assistant, and a container (for carrying the product) A container is fixed to a trailer so it needs to be coupled to a lorry at the start of a Job. (Single container can transport only one chemical product due to safety requirements) Payments for a job depends on customer type, product type (No Risk, High risk) and the load type (small, medium and large). Transport operations are run from 9 regional depots. Jobs are allocated to individual depots to service. Depots hold, manage and maintain their own transport units which are permanently allocated to them to service Jobs. Normally transport units are held at the base Depot they belong. The final system should be able to provide the required information for management decision making and to handle daily operations efficiently and
effectively.
Activity 01
Activity 1. a. Identify the user and system requirements to design a database for the above scenario. b. Identify entities and attributes of the given scenario and design a relational database system using conceptual design (ER Model) by including identifiers (primary Key) of entities and cardinalities, participations of relationships. c. Convert the ER Model into logical database design using relational database model including primary keys foreign keys and referential Integrities. It should contain at least five interrelated tables. Note:-It is allowed to have your own assumptions and related attributes within the scope of the case study given. Activity 1. a. Explain data normalization with examples. Check whether the provided logical design in task 1.1 is normalised. If not, normalize the database by removing the anomalies. b. Design set of simple interfaces to input and output for the above scenario using Wireframe or any interface-designing tool. c. Explain the validation mechanisms to validate data in the tables with examples. Activity 1. a. Check whether the given design (ERD and Logical design) is representing the identified user and system requirements to access the effectiveness of the design.
Activity 2
Activity 2.
from the developed database Group by Order by Having Between Where
Activity 3
Activity 3. a. Provide a suitable test plan to test the system against user and system requirements b. Provide relevant test cases for the database you have implemented Note:- Learner needs to give expected results in a tabular format and screenshots of the actual results with the conclusion Activity 3. a. Explain how the selected test data in task 3.1 b) can be used improve the effectiveness of testing. Activity 3. a. Get independent feedback on your database solution from the non- technical users and some developers (use surveys, questioners, interviews or any other feedback collecting method) and make recommendations and suggestions for improvements in a separate conclusion/recommendations section.
Activity 4
Activity 4. a. Prepare a simple users’ guide and a technical documentation for the
support and maintenance of the software. Activity 4. a. Your technical documentation should include some of the UML diagrams (Use case diagram Class diagram, etc.), flow charts for the important functionalities, context level DFD and the Level 1 DFD Activity 4. a. Suggest the future improvements that may be required to ensure the continued effectiveness of the database system.
P2 Develop the database system with evidence of user interface, output and data validations, and querying across multiple tables. P3 Implement a query language into the relational database system M2 Implement a fully functional database system that includes system security and database maintenance. M3 Assess whether meaningful data has been extracted using query tools to produce appropriate management information. LO3 Test the systems against user and system requirements
P4 Test the system against user and system requirements. M4 Assess the effectiveness of the testing, including an explanation of the choice of test data used. LO2 & LO D2 Evaluate the effectiveness of the database solution in relation to user and system requirements, and suggest improvements. LO4 Produce technical and user documentation P5 Produce technical and user documentation. M5 Produce technical and user documentation for a fully functional system, including diagrams showing movement of data through the system, and flowcharts describing how the system works. D3 Assess any future improvements that may be required to ensure the continued effectiveness of the database system.
