PART 1 (Due Week 3)

(1) Project Description. 10 points.

Provide an overview of your project identifying the major components as part of a database design. The format is an executive summary to be presented to management for review.

(2) Entity-relationship Diagram. 30 points.

Use the entity-relationship diagram (crows-foot) notation to design your database system. Be sure to: (1) identify entity types; (2) describe relationships between or among entity types; (3) identify modality and cardinality for each relationship; (4) identify associative entities and intersection data; and (5) label primary and foreign key attributes.

Your entity-relationship diagram will have a minimum of six (6) entity types of which at least two (2) are associative entities with intersection data. The ERD is accompanied by a brief explanation of each component in the entity-relationship model.

Note: You can use Microsoft Visio, Word, PowerPoint, or Access as a diagramming tool. Please obtain approval from your instructor regarding the use of other diagramming tools.

PART 2 (Due Week 5)

1.       SQL Data Definition Language. Three (3) points each for 1.1 and 1.2; and four (4) points for 1.3.

1.1.    Create a base table. Write the SQL to create a table based on one of your entities. Be sure to identify the primary key as part of your SQL syntax.

1.2.    Create a view. Write the SQL to create a view on the base table.

1.3.    Show the base tables with data. Show a base table along with six rows containing data for three entities in your entity-relationship diagram. (Display each table in the form of an MS Word table.)

2.       SQL Data Manipulation Language (insert, update, and delete). Five (5) points each for 2.1, 2.2, and 2.3.

2.1.    Insert a row. Write a SQL query to insert a row into one of your base tables.

2.2.    Update a row. Write a SQL query to change a data value in the inserted row.

2.3.    Delete a row. Write a SQL query to delete the row from your base table.

3.       SQL Data Manipulation Language for data retrieval. Five (5) points each for 3.1 through 3.7

For 3.1 through 3.7, write the SQL query AND show the output using the data in your base tables.

3.1.    Write a SQL query using a comparison operator (e.g., =, >, <).

3.2.    Write a SQL query using the “AND” or “OR” operator.

3.3.    Write a SQL query using the “BETWEEN” or “LIKE” operator.

3.4.    Write a SQL query using a built-in function.

3.5.    Write a SQL query using the “GROUP BY” clause.

3.6.    Write a SQL join query using two or more base tables.

3.7.    Write a SQL subquery using two or more base tables.


PART 3 (Due Week 7)

For the database concept you have chosen for Parts 1 and 2, provide the following:

·         Display your entities/tables in First Normal Form (10 points)

·         Display your entities/tables in Second Normal Form (10 points)

·         Display your entities/tables in Third Normal Form (10 points)

You may need to rework your relationships to achieve this. For each form, provide the tables and the defining associations. An example of the table overview can be seen on page 184 of the Fundamentals of Database Design textbook. An example of defining associations can be seen on page 185.

Next, define three (3) business processes that will access a particular table and attribute. For example, “a customer login process will require accessing the CUSTOMER table and retrieving the CustomerID and CustomerPassword attributes”. Provide detail on what the business process is and who is involved. For each business process, provide the SQL that would need to be run to access it in the first, second, and third normal forms you provided in the previous section.

(15 points)

Finally, choose an optimization strategy as defined in Chapter 8, whether physical or logical, and describe how it could potentially benefit any or all of your normal form examples. Provide a comparison between a use case with and without this strategy implemented.
