NORMALISATION EXERCISES-PROPERTY MAINTENANCE Mrs Susan Smart has been building up a small property investment portfolio over the years. She uses a spreadsheet to keep track of all the repair and maintenance work done on her individual investment properties by different repairers. Susan employs a local real estate agent to look after each of her properties. She uses the same agent to manage multiple properties if they are in the same region or area. In some cases, Susan has used a second mortgage to finance the renovation of the property. Susan found it hard to see an overall picture of her portfolio from the spreadsheet as it is growing bigger and bigger over time. She learns about the effectiveness of relational database to manage a large amount of information in a recent seminar. She asks you to do her a favour by converting her property portfolio spreadsheet to a relational database so thi she can perform queries and print out reports. The following is an extract from her property portfolio spreadsheet. You are required to: 1. Normalise the following spreadsheet into tables in the third normal form (3NF) 2. Create an Entity Relationship Diagram (ERD) based on the tables in (1) above.
