Module Learning Outcomes The following LOs are achieved by the student by completing the assignment successfully 1) Apply normalization techniques to reduce redundancy in a database. 2) Design the logical structure of a database using Entity-Relationship diagram. Assignment Objective This is an individual assignment aimed to give the student exposure in understanding, designing, building and analyzing database systems for a given real-time based scenario and be able to conduct optimal strategies for efficient management of databases. Assignment Tasks Task 1: Complete the work proposal in Microsoft Word file format (may include possible answers based on your initial understanding). Work proposal for the assignment must be submitted before 23:59 Hrs on Thursday, 07/05/2020 and must include: MEC_AMO_TEM_034_01 Page 1 of 11 Relational Database Systems (COMP 1005) – Spring 2020-CW1 (Assignment) - ML a) Understanding of deliverables – a detail description of deliverables. b) General overview of proposed plan - initial understanding of solution to task 2 which includes, the name of entities, associative entities and relationships and a brief write up on the concept of referential integrity. Initial understanding of solution to task 3 which includes the process to be followed for normalization and a brief write up on the concept of data integrity. c) Timeline and references for completion of task 2 and task 3. The work proposal must be submitted in a word file through the link available in Moodle. (4+3+3=10 marks) Task 2: Scenario: Oman Tourist Center (OTC) rents cars to its customers on rent. A car is rented to one or many customers. A customer is characterized by a unique customer number, other attributes of the customer entity have to assumed by you (minimum four attributes are expected). A car is identified by a unique serial number. The other attributes are model number, manufacture year and class. A customer should have rented at least one car or many cars from OTC. Whenever a customer rents a car, OTC wishes to record the various rental details (you need to assume and add at least 4 attributes in addition to referential keys). A car is manufactured by exactly one manufacturer. A manufacturer manufactures at least one or more cars. A manufacturer is defined using unique number, name, country, sales representative name and telephone number. A car has had many maintenance events. A maintenance event corresponds to exactly one car. Maintenance event is characterized by unique repair number, date of maintenance, mileage, repair time. a) Construct the Entity Relationship Diagram (ERD) for the above given scenario. Identify all the entities, associative entities, attributes of each entity including primary key, relationship between the entities and cardinality constraints. State the necessary assumptions for your recommended database design. (30 marks) b) Analyze the above given scenario and discuss about the possible structure of associative relation by giving the details on the datatype and the size of each attribute. State any assumptions necessary to support your design. c) Discuss referential integrity constraints in the design arrived at in task 2(a).
