Access database assignment
You operate a small share trading business, buying and selling shares for a small group of investors and companies.  To date you have used a spread sheet to record transactions but you have decided to adopt a database approach as you have been told this is a better way of operating your business.
A design has been prepared by an outside consultant but as you have some knowledge of Access, you have decided to complete the task yourself.
You have been given the table structure of the database and notice that three tables have been suggested. These are listed below.The field names detailed in bold are kAey fields
Tables
1.    Trades(Transaction ID, client ID, share code, transaction date, no bought/ sold, transaction price/share)(Figure 1)
Figure 1: Trades table (design view)
2.    Company(share code, share name,  sector) (Figure 2)
Figure 2: Company table (design view)
At present you have transaction data and company details stored in a spreadsheet and you realise this will need to be transferred from the supplied Excel spreadsheet into the Access database after the file has been created.The Excel file is  SHARETRADES T2 2012.XLXS which is located on the subject portal. You will need to modify the field sizes in all text fields (see figure 3) and to add in the design view some simple comments in the description column that describe the purpose of the field.
You have kept client details in a separate list and this will need to be entered into the database file after you have created the appropriate table for the data.  You also trade shares for your own private needs and have decided to include the details in the database. Client address details (suburb only) should be included
3.    Client(client ID, client name, client address)(Figure 3)

Client details that you need to enter into Access are as follows (Figure 4)

This will require the inclusion of a calculated field.
