Database and Information Retrieval

Assessment Task- Project Documentation and Database

Introduction

• This assessment is for students to develop the capacity to design and implement a database.

• This assessment requires students to identify business rules, create a data dictionary, create an EntityRelationship diagram, and develop an Oracle database using SQL.

• This is an individual assessment task.

• The project documentation submitted should include business rules, data dictionaries, ER diagrams, SQL source code such as q1.sql, and SQL spool files such as q1.txt.

Unit Learning Outcomes

• Of the three Unit Learning Outcomes (ULOs) of this unit SIT103, this assessment task will focus on the last two ULOs. These are:

o ULO 2 - At the end of this unit students will be able to evaluate data models and apply data modelling techniques to capture the data aspects of real-world situations.

o ULO 3 - At the end of this unit students will be able to design and develop relational databases by using SQL and a database management system.

• The assessment of this task (Project Documentation and Database) will indicate whether students can partially attain these unit learning outcomes.

Instructions

• Read these instructions and the following 4 questions.

• Answer as many questions as possible.

• You should consider which questions to answer because Question 1 is at the Pass level, Question 2 is at the Credit level, Question 3 is at the Distinction level, and Question 4 is at the High Distinction level. If you are interested in obtaining a:

• Clearly identify your answers 1a, 1b, 1c and so on, as this will ensure that the marker can find your answers.

• Place your name, ID and answers in your document. Please note that MS Word (docx) or PDF files may be submitted.

• As there will be several files that you will submit, you will place all files in a folder and ZIP that folder.

Question 1

Pass level

Assessing this question focuses on whether students can demonstrate the ability to:

• list business rules for a simple database,

• create a data dictionary for a simple database (2 tables, 1:N), • create an ER diagram for a simple database (2 tables, 1:N), and

• develop a simple database (2 tables, 1:N).

Task www.winelovers.com provides data and information related to wine. It uses a small database containing data about different wines and winemakers. Each wine can only be manufactured by one winemaker, but each winemaker can produce several wines. However, clearly it is possible that a new winemaker has not produced a wine.

For this scenario:

(a) Determine the business rules.

(b) Develop a data dictionary.

(c) Develop an ER diagram. Clearly label all entities, primary and foreign keys, relationship, connectivity and cardinalities.

(d) Develop an SQL script, say q1.sql, to run on Deakin's Oracle database which:

1) removes previous tables related to this question, e.g., drop ...

2) creates these two tables, e.g., create ...

3) inserts all data from Table 1, e.g., insert ...

4) uses the spool command to start recording to a file, e.g., spool /home/username/q1.txt

(please replace username with your Deakin login name)

5) turns on the echo, e.g., set echo on;

6) displays the wine name, vintage and price of all wines costing less than $20, e.g., select ...

7) displays the wine name, price and maker of all wines made in 2012, e.g., select ...

8) turns off the echo, e.g., set echo off;

9) turns off the spooling, e.g., spool off;

Question 3

Distinction level

Assessing this question focuses on whether students can demonstrate the ability to:

• list business rules for a database,

• create a data dictionary for a database (2 tables and a junction table, N:M), • create an ER diagram for a database (2 tables and a junction table, N:M), and

• develop a database (2 tables and a junction table, N:M).

Task

Use the same scenario as in Question 2, but instead of two tables with a many-to-many relationship you will focus on three tables: the two tables for wine and retailer plus a junction table to represent the ‘sell' relationship.

For this scenario:

(a) Determine the business rules for these 3 tables.

(b) Develop a data dictionary for these 3 tables.

(c) Develop an ER diagram for these 3 tables. Clearly label all entities, primary and foreign keys, relationship, connectivity and cardinalities.

(d) Develop an SQL script, say q3.sql, to run on Deakin's Oracle database which:

1) removes previous tables related to this question, e.g., drop ...

2) creates these 3 tables, e.g., create ...

3) inserts all data from Table 3 into these 3 tables, e.g., insert ...

4) uses the spool command to start recording to a file, e.g., spool /home/username/q3.txt

(please replace username with your Deakin login name)

5) turns on the echo, e.g., set echo on;

6) displays the wine name, vintage and price of all wines at Dan Murphy's costing less than $20, e.g., select ...

7) displays the wine name, price and retailer of all wines at Dan Murphy's made in 2012, e.g., select ...

• Each wine goes well with 0 or more foods, and each food goes well with 0 or more wines. A five point scoring system is used to rank compatible wines and foods. For each score there is a small description of a few words such as:
o o o o o 1
2
3 4
5 try another wine nearly compatible compatible very compatible excellent

For this scenario:

(a) Determine the business rules for all tables including junction tables.
