Acme RealEstate Pty Ltd is a small real estate agency that has a number of branches throughout the state. They have decided to implement a new database to manage their business activities. They had employed a consultant to undertake the work, however, after creating an ER diagram, a file containing the statements to create a part of the database and to insert some sample data, the consultant left the business. The management executive decided to commission you as a consultant to continue the work utilizing the ER diagram that has been created. You are required to analyze and improve the ER diagram, to develop a relational database schema, create normalize relational data structures, implement and load the database, and to write the required SQL queries. During the process of finalizing the design and implementing the database, you may decide to alter the structure of the ER diagram, for example there may be tables that are not in 3NF that need to be changed or names of fields that you would like to alter. If you do decide to make changes to the structure please include within your documentation an ER diagram incorporating the changes, a short statement summarizing the changes that have been made and a rationale for why the changes were necessary.
