Part I: The first computer-based information system that The Doctor is interested in is a Database Management System (DBMS) utilizing Microsoft Access (any version from Access 2007 to current). The DBMS will store all the business's customer details, information about the stock items that the business sells, the suppliers that the business uses and all postal order transactions for the business. It will allow The Doctor to run a number of queries on the data, which the business has specified below, and they wish to be able to print out an invoice for each customer at the end of each month.
Part II: The next computer-based information system that the business is interested in is a Decision Support System (DSS) utilizing Microsoft Excel (any version from Excel 2007 to current). The DSS will analyze sales trends for the business to determine future courses of action for the business.
The Doctor would like the information in the Database Management System (DBMS) (Assignment 1 Part A) imported into Microsoft Excel (any version from Excel 2007 to current) so that the information can be summarized as a report and some future analysis of sales trends performed. The suppliers used by the business, source items from either Ireland (IE) or New Zealand (NZ). They allow the business to select from either of these two regions on an ad hoc basic depending on the most favorable exchange rate at the time.
The Doctor has noted that a number of the business's competitors are providing a discount to customers who place large orders. The business would like to see what affect adopting a similar policy would have on the business. The business has also noted a growing number of online businesses are starting to provide free freight delivery as a way of encouraging more online business; the business would like to run a number of scenarios based on potential Mark-up and Freight options to ascertain the best combination for the business if they were to adopt this policy too.
Part III: The Doctor also has a number of questions relating to the two computer-based information systems in Part A & Part B that he would like you to answer, prepare an Essay to answer these questions he has listed.
Assignment Part A: (Database Management System)
Your firm's Systems Analyst has developed a database structure that has been determined to be suitable to create a database to store The Doctor's customer, item, supplier and order data for the business, which has been attached:
Table:
tblCustomers
Fields: Cust ID(Primary Key), Title, Family Name, Given Names, Date of Birth, Address, City, State, Postcode, Freight Distance (Km), Mobile Number, eMail Address, Mailing List.
Table:
tblItems
Fields: Item ID(Primary Key), Type, Description, Size, Freight Weight (Kg), Supplier ID, In Stock, On Order, Cost Price (EE), Cost Price (SG).
- IE is the country code for Ireland (their currency is the Euro)
- NZ is the country code for New Zealand (their currency is the Dollar)
Table:
tblSuppliers
Fields: Supplier ID(Primary Key), Supplier Name, Address, City, State, Postcode, Phone Number, Recommended MarkUp
Table: tblOrders
Fields: Cust ID, Item ID, Order Date(Primary Key), Dispatch Date, Order Qty
Note: The primary key of the Orders table is a combined multiple-field key. It has three fields in one key.
The Doctor has provided to us a partial list of the business's customers, stock items, and suppliers and a partial list of the business's postal orders placed between January and June 2019 to use as test data in four comma delimited text files, which can be found on your firm's Intranet (CIS5100 Study Desk).
Dr Tara Dis, your manager, has set up the following tasks for you to complete for this phase of the project:
1. Create a Database and import the four (4) Text files into four (4) Tables
2. Modify Table Design
3. Set Primary Keys
4. Create Relationships between the Tables
5. Edit Customers Table
6. Create Data and Update Queries

Assignment Task 1: Create and Import
Create a new blank Access Database (using any version from Access 2007 to current) and name it [lastname] [initial] _ [student number] _ [course code] _ assign1_(part_a).accdb
eg.genrichr_0050051005_cis5100_assign1_(part_a).accdb.
Import the four sets of data from your firm's Intranet (CIS5100 Study Desk).
The easiest and quickest way to import data into Access is by using the Import Text Wizard. The following steps must be followed carefully to ensure the data is imported correctly:
Importing Tab Delimited Text files into Access (any version from Access 2007 to current) using the Wizard
1) On the External Data tab, in the Import & Link group, click the Text File data source icon.
2) In the Get External Data - Text Filewizard popup, browse to find the 'Assignment01 Text File Customers.txt' text file and select the Import the source data into a new table in the current database option - then click OK.
3) Select the Delimited - Characters such as commas or tab separate each field option on the first page of the wizard - then click Next.
4) Select the Tab option on the second page of the wizard and turn on the First Row Contains Field Namescheck box - then click Next.
5) Set the following for each field on the third page of the wizard:
- Field Name - keep the field name as it appears when imported
Note: Changing Field Names rather than using Captions will result in loss of marks.
- Data Type - giving each an appropriate data type (students will be marked on their logical choice of data types, based on the sample data provided).
- When you are sure that each field has the appropriate data type, click Next.
6) Select No Primary Key option on the fourth page of the wizard - these will be set in Task 2 - then click Next.
7) Name the table tblCustomers on the final page of the wizard and click Finish.
Repeat the above 7 steps for the rest of the text files naming each Database Table as follows:
Assignment Task 2: Modify Table Design
Modify the four imported tables' structures using the given Table Specifications, from the section above, in Microsoft Access using Table Design View:
- Use the above table specifications, checking that you have the correct table names and field names.
- Check that all fields have the appropriate Data Typefrom the following:
o Text, Number, Date/Time, Currency, Yes/No, Hyperlink.
- Add appropriate Field Descriptionsto ALL data fields with a well-structured description, eg. for CustID an appropriate description would be:
Customer Identification | Data Type: Short Text: 3 Characters
- Ensure that you also set properties for each field where appropriate. You MUST set the following:
o Field Size- set appropriate logical fields sizes for all Text and Number data types (numbers without decimal places should be set to be either binary, integer or long integer; and numbers with decimal places should be set to be single or double).
o Caption- set an appropriate English caption for all fields where the field name is not in English (eg. Customer ID for CustID).
o Format- set an appropriate format for all: Yes/No and Date data fields; Text data fields that should be stored in Upper-Case (State); Hyperlinks data fields that should be stored in lower-case (EmailAddress); and numbers that contain currency or percentages.
- IE is the country code for Ireland - should be formatted in Euros;
- NZ is the country code for New Zealand - should be formatted in Dollars.
o Decimals- set an appropriate number of decimal places for any single or double numbers
o Default Value- set an appropriate default value for all Yes / No data Fields
o Required- set any data Fields that must contain data to Required and leave any Fields where data is optional as unchecked.
o Validation Ruleand Validation Text- include appropriate Validation Rules for each of the following data Fields: Title; State; and Item Type. This ensures that only limited value options can be entered for these data Fields.
Assignment Task 3: Set Primary Keys
Set the Primary Keys for the four (4) Tables as per the following table specifications in Microsoft Access using Table Design View:
Assignment Task 4: Create Relationships between the Tables
Create the following relationships between the four (4) tables:
- tblCustomers to tblOrders
- tblItems to tblOrders
- tblSuppliers to tblItems
Assignment Task 5: Edit Customers Table
Edit Customer ID 112 in the Customers Table as per the following instructions in Microsoft Access using Table Datasheet View:
1. Change the Title, Given Names and Family Name to your own details.
2. Change the Address, City, State and Postcode to your own details.
3. Using www.whereis.com.au look up the distance between your current address and Toowoomba QLD 4350(to the nearest kilometre) - change the Freight Distance to this new value.
4. Change the Mobile Number to your student ID eg. 0061 099999
Do not use the u1099999 version.
5. Change the Email Address to your own details.
6. Select that you would like to be on the Business's Mail List.
Assignment Task 6: Create Data and Update Queries
Create the following Three (3) queries using the Query Design View. Use the names given for each query to avoid confusion for the client (make sure you submit them in the order given below).
A) You must create the Queries using Access Design View, if you create the Queries using SQL this will result in ZERO marks for the Query.
B) Query names must conform to the Leszynski Naming Convention (LNC), as per the Naming Convention for Access Database Objects document in the Practical Appendixes found on the Study Schedule and Module Materials - including the Query Number and Two Meaningful Words to describe the query eg.qry1XxxxxxXxxxxx.
C) Not all queries will require the inclusion of all four tables; you must decide which tables are appropriate for the generation of each query's output. Only tables needed should be included in the query design as extraneous tables could cause problems with the query results
Query 1: Import Duty Ireland(IE) Cost Price Increase:
A new Australian import duty of 2.75% has been added for all products being imported from Ireland (IE)and The Doctor has asked you to develop a query that will update the Cost Price from Ireland(IE) of all items that are currently on order. As it would be considered profiteering, it is important that the query does not update the Cost Price of items already in stock.
Create an Update Querythat will raise the Ireland(IE) Cost Price for all items on orderthat are not in stockby 2.75%. It is always good practice to backup any data before running an update or a delete query. The following steps should be followed to achieve this Query:
- In the List of Tables, copy the table called tblItems and paste it with the new name tblBackupItems.
Use tblItems for this Update Query, not your back up table tblBackupItems. If you have difficulties with this query and need to restore your data to the original values, you can copy columns as necessary from tblBackupItems to tblItems and start again.
- Create an Update Query that will increase the Cost Price (IE) in tblItemsby 2.75%for all items currently not in stockbut on order.
- Include rounding to 2 decimal places with the update calculation by placing the following function around the update formula: ROUND(update_formula,2)
Query 2: Late Dispatched Orders Form Query:
The Doctor would like to have a single query that the business can display within a form (Task 7: Form 1) to see within this single query the customers who are either:
i) Living in New South Wales, have had items dispatched late (between 15thJune and today) and where the item was ordered after the 1stJuneand the item is in stock
Or
ii) Living inVictoria, have had items dispatched late (between 20thJune and today) and where the item was ordered after the 5thJuneand the item is in stock
Or
iii) Living inQueensland, have had items dispatched late (between 25thJune and today) and where the item was ordered after the 10thJuneand the item is in stock
Create a Select Query that will display the CustID, Full Customer's Name (including Title, Given Names, and Family Name), Full Customer's Address, Date of Birth, eMail Address, MailingList, ItemID, Full Item Details (including Type, Description, Size, Freight Weight and Supplier Name), OrderDate, Dispatch Date and OrderQty for those customers.
Limit the data in the single query to either customers (using the OR Criteria):
i) living inNewSouth Wales, who have placed Orders after the 1stJune 2019and where these orders were only dispatched between the 15thJune 2019 and today (using the BETWEEN criteria tool and the DATE() function), and where the business currently has that item in stock
ii) OR living in Victoria(using the OR criteria row), who have placed Orders after the 5thJune 2019but where these orders were only dispatched between the 20thJune 2019and today (using the BETWEEN criteria tool and the DATE() function), and where the business currently has that item in stock
iii) OR living in Queensland(using the OR criteria row), who have placed Orders after the 10thJune 2019but where these orders were only dispatched between the 25thJune 2019and today (using the BETWEEN criteria tool and the DATE() function), and where the business currently has that item in stock
Display the results sorted in Ascending Order by State and Order Date, check that have you included all necessary Fields and ensure that you only display the required Fields.
- Query 3: Invoice Query with Calculated Fields:
The Doctor would like to have a query that the business can use to produce customer invoices (Task 8) to see how many customers on our Mailing List ordered Statues and Busts, or Props and Replicas, but only those items that werenot considered to be Torchwoodrelated, and where the Item is in stock. This query should also calculate the selling price (based on goods purchased from the New Zealand (NZ) and order total, both of which will be needed on the customer invoices.
Create a Select Query that will display the CustID, Full Customer's Name (including Title, Given Names and Family Name), Full Customer Address, ItemID, Full Item Details (including Type, Description, Size, Weight, and Supplier Name), OrderDate, and OrderQty, including two calculated Fields - Selling Price (AU) and Order Total (AU).
Limit the query to only those customers on our Mailing List who ordered a"Statues and Busts" or"Props and Replicas"(using the IN criteria tools),where theItemDOES NOT contain the word "Torchwood" (using the NOT criteria tools and the LIKE criteria tool), and where the business currently has that item in stock.
Assignment Task 7: Create an Invoice Report
The Doctor has provided you with the following sample Invoice. The client requires you to develop a similar invoice for their business.
Using all Fields from Task 6 Query 3, create in the Report Wizard (using the Block Report Wizard Template) a single Report called rptCustomerInvoice that produces a professional looking invoice for the business.
The invoice must have the following attributes:
- The report must contain at least all the report elements displayed in the sample invoice (above) and it must use all of the data fields shown in Query 3.
- The report must be grouped by CustID.
- Each Customer's invoice must be on a separate page.
- Each Customer's invoice must have part of the Customer's address merged into a single Field including City, State and Postcode by modifying one of the Fields to include:
[City] & " " & [State] & " " & [Postcode]
- Each Customer's invoice musthave Today's Date in the Page Header
- Each Customer's invoice must have an Invoice Total for each customer
- Each Customer's invoice must not have any extraneous data including Grand Totals, Page Numbering, nor Summary Information.
- Each Customer's order must have the Order Date in the Details Section
- Each Customer's order must have alternating background colours in the Details Section
- Each Image on the invoice must be inserted using the Image Control and must have the following properties:
