Assessment details for ALL studentsAssessment item 2Due date: Friday of Week 10 (11:45 pm AEST)Weighting: 30%Length: N/AObjectivesTo develop a conceptual data model diagramTo perform logical design and physical designTo implement a databaseIntroductionIn this assessment, you are required to create a suitable database in MS Access for the given case study. You need to do the following:Design and draw an Entity Relationship diagramProvide answers to the given questions related to ER diagramPerform logical and physical design Create a Database in MS-AccessCase StudyHassle-free Dry Cleaners Australia (HDCA) Victor owns and operates Hassle-free Dry Cleaners Australia (HDCA). HDCA offers a full range of services in all their stores including garment preservation, quality business shirt service, ironing, etc. Currently, HDCA staff record all their customers’ details and relevant transactions manually into a register. The collection process at HDCA starts when a customer walks-in and provides the HDCA staff with their details (First Name, Last Name, Number, Street, Suburb, Contact number, type of clothes, customer preferences, Quantity, preferred date and time for pick-up). Upon receiving the details, HDCA staff members provide the customer with the total cost for cleaning clothes, etc. If the customer is happy with the quote, then HDCA staff will record the customer’s credit card details (credit card number, name on the card, type, expiry date and 3 or 4 digit code). Once the clothes are collected by HDCA staff, these will be washed or dry cleaned as per the customer’s preferences and kept ready for collection by the customer. At the time of delivery, customers are provided with a hard copy receipt which includes Receipt Number, Receipt date and Amount paid.As part of your assessment, you are expected to find out the relevant attributes of the entities and relationships. Each entity should have at least one additional attribute in addition to the identifying attribute. To avoid plagiarism, the case study does not clearly specify the details such as attributes and their types, relationship constraints, etc., that are required to design and draw the ERD. Hence, you are expected to assume such details which have not been mentioned clearly in the above case study.1Draw an appropriate ER diagramUse the symbols as prescribed in your unit-textbook to draw the ER diagram for the above case study. 2 List your assumptions and justify the relationship constraints in your ER diagram. Your answers should be relevant to your ER diagram for the given case study only.3 Create Logical Design Map your Entity Relationship model into Relations and make sure that all the relations are in BCNF. Provide all the relations in the following format:Student (StudentId, StudentName, Street, Suburb, State, PostCode, Email, ContactNumber)Course (CourseId, CourseName)Course_Student(CourseId, StudentId, grade) foreign key (CourseId) references Course.CourseIdforeign key (StudentId) references Student.StudentId4 Provide Physical Design As part of the physical design, provide the column specifications for any one of the relations/tables that you have created. Column specifications should be presented in a tabular format showing the details such as column name, data type (length for varchar and char types), key, required, default value and remarks if any. Hint: Refer to page 341-347 in the text book (8th edition).Refer to page 331-333 in the text book (7th edition).5 Implement Database Create all tables and their relationships that are relevant to your case study in a Microsoft Access database. All tables should contain their respective columns. All the relationships should have appropriate referential integrity and cascade options applied. The properties for all the columns of the table, that you have selected in the above physical design section, should have all the column specifications properly applied. You do not need to create any form, query or report. You do not need to insert any records in the tables.How and what to submit:You must make an electronic submission for this assessment using the appropriate assessment submission link in the unit website. Your submission must be a single ZIP file which contains your assessment work in the following two files:A Microsoft Word document containing1.Entity Relationship Diagram2.Assumptions and Business Rules3.All the relations (after the logical design)4.Column specifications for any one table onlyA Microsoft Access database containing1.All tables and their relationships--------------------------------------------------------------------------------------------------------------Marking Criteria:Item Maximum MarksEntities have been identified and drawn correctly. 5Provided appropriate attributes including identifying attribute(s) for each entity. 5Drawn correct relationships; used proper symbols and shown min and max cardinalities. 5Provided relevant assumptions 2Correct BCNF Relations including foreign key references. 5Column Specifications for the selected Table under section 4 (Provide Physical Design). 2Database with Tables (2 marks) and Relationships (2 marks). Correct data type and properties (2 marks) for all columns/attributes of the selected table under section 4 (Provide Physical Design). 6Penalty due to plagiarism/copying Late Penalty: Less 5% of available marks per calendar day.
