Read the marking comments of assignment-1 carefully and talk to your marker if necessary. The specification of this assignment 1. Database implementation • You are to design and implement the ER model of assignment-1, including entities/associative entities, relationships and cardinalities, into a Microsoft Access database. You need to make sure that your database is compatible with MS Access 2010 for marking purpose. • You need to ensure that relations of your database meet 3NF. • Your database needs to include enough sample data to support the required SQL queries. 2. SQL query As a way to demonstrate success, you are to implement a series of queries on the database to reflect the business logic of The Best Home. Note: You are to create the queries manually by using the SQL view of MS Access query builder to demonstrate your competency in SQL. Failing to do so may result in marks to be deducted. Query-1: List all the contact details of a particular customer to show: • The customer’s name • The contact type e.g. email • The contact details e.g. w.li@cqu.edu.au Note: the customer’s name is a parameter to enter when executing this query in Microsoft Access. A customer could have more than one contact e.g. email, mobile and home phone. Query-2: List all the rental properties that the asked prices (the price on the advertising) are the same as the rent prices (the price on the rent contract) to show: • The property type • The property address • The asked price 2 • The actual rent price Query-3: List all the sale properties that have been available for 6 months but not sold yet to show: • The property type • The property address • The property sale price • The property available date • The property manager’s name Query-4: List the properties that were sold in a particular suburb e.g. ‘The Range’ to show: • The buyer name • The property manager who sold the property • The property type • The property address • The asked price • The deal price • The date when the property was sold Note: the suburb name can be hardcoded in your query.

Find the supervisor of the property manager, who is currently looking after the property to show: • The property type • The property address • The owner name • The property manager’s name • The supervisor’s name of the property manager Note: the property address can be hardcoded in your query. Query-8: List all property managers in descendent order of the number of properties that they have been looking after to show: • The property type • The property address • The property status • The property manager’s name 3.

Implementation document You are to write a short report to demonstrate that you have thought carefully about the issues that arise when implementing the database and the SQL queries. You need to address: • How you populate data for multi-valued attributes to make sure that they are enough to support the required SQL queries. Concrete examples from the database are required to justify your statement. • Whether it is necessary to implement the property address as a composite attribute for the required SQL queries. Concrete examples from the database are required to justify your statement. Submission To submit your assignment, you need to provide: 1.
