Designinga Relational Database
Step 1. Understand the specification of the problem
Read the following paragraph carefully. Multiple times, if necessary. Then follow the process we learned in Lab 2 to annotate the primary terms and actions.
Basketball is one of the most popular sports in the United States. Basketball tournaments consist of games between two teams at various stages (league, playoff, final, etc.). Each individual game in the tournament is played between two competing teams played at a specific city or stadium with a certain capacity, and attended by a number of spectators. The matches may also be televised on a TV channel, and viewed by an estimated number of TV viewers. During each match, the teams typically play two halves (which may be further divided in quarters depending on the tournament). Players score points, commit fouls and perform blocks, rebounds, and assists. Each match ends with a score with the team with the higher score being the winner. Players play for a team and have a position and a jersey number in addition to physical attributes like weight, height, birthday, etc. Players may switch teams from one season to the next. In our scenario, let’s assume that they do not switch teams mid-season. Each team has a support team with at least a coach, assistant coach, and physio.
Step 2. Identify Terms, actions and Business Rules
Start an empty Microsoft Word document, and put your name and PantherID at the top of the document. Now for Step 2 – first write down all the terms that you identify that you feel should be entities. Then write down all the actions between the terms. Then write down as many business rules that you can think of.
Step 3. Draw an ER model for the scenario.
Create an E-ER model for the above scenario using the diagramming tool of your choosing, but follow the constructs we used in the lab. Make sure you indicate all your strong entites, weak entities, supertypes and subtypes, cardinality and participation indicators, and primary keys for every strong entity. Make sure you come up with at least 3 attributes for each entity.
Copy and paste this diagram into your Word document.
Step 4. Relational Schema
Design the schema of the database from your E-R diagram. You can do this by just listing all the tables and attributes in the Word document. Indicate the primary keys with underlines and foreign keys with asterisks as we did in the lab.
Finally, write an SQL script with the CREATE TABLE, ALTER TABLE commands to create the complete schema of your design. Then create at least one row in each of the tables using insert statements. Your script should include the DROP, CREATE, ALTER and INSERT statements for creating all the tables and keys, followed by inserting at least one row in each table. You may need to insert more than one row in some tables. Save this script SEPARATELY in a text file (extension .txt). Do not include the DDL statements in your Word Document.
What to Submit
You will submit the following four documents:
The Word document containing your design, including the business rules, and all notes leading to your design. (.doc or .docx)
The original ER model in PDF format (.pdf)
The SQL script containing your schema creation and insertion commands (must not be in the Word document, and submitted as a .txt file)
Test your commands in livesql and make sure all commands run properly. Submit the transcript of running your script in LiveSQL in PDF form (in PDF – must show all tables created and rows inserted). (.pdf)
