Summary:
- To apply all acquired knowledge in the last Project Assignments to create a Database Scheme. For this project, the ERD is provided to you.
Deliverables:
SQL Script with your name as follows: YourLastName_Project_Ph3.sql.
MS Word Document with your OUTPUT, named as follows: YourLastName_Project_Ph3_Output.doc.
ZIP file to include the two files mentioned above.
- Required Software:
- MySQL DBMS by Oracle. MySQL Community Server and MySQL Workbench.
- Follow Step 1-3 for your Course Project Phase phase 1, to install the required software components.
Lab Steps:
Step 1: Analyze the ERD for a student information system provided below. Be alert for the specifications provided for: 1) Entities, 2) Attributes, 3) Primary Key, and 4) Relationships. You will need to have a clear understanding for these components to create your database using MySQL.
- Step 2: Create a New Database in MySQL, Produce SQL File, Drop Table
Create a new Database, as you did in your Course Project Phase 1 deliverable and you already created a database using the MySQL DBMS. Reference the attached video (Course Project Ph1 Video.mp4), for a demonstration to create a new Database using MySQL. This video was initially presented to you for phase 2 of your project. Also, reference the supplemental text: Available for Free download as part of our UC Library. MySQL Database Usage & Administration. (2010). By Vaswani, Vikram. McGraw Hill. ISBN: 978-0-07-160550-2. Link to UC Library: http://search.ebscohost.com/login.aspx?direct=true&AuthType=shib&db=nlebk&AN=291311&site=eds-live&ebv=EB&ppid=pp_ii
Utilize the SQL dialect you learned so far in this course for MySQL. Use the file supplemental textbook: MySQL Database Usage & Administration. (2010). By Vaswani, Vikram. McGraw Hill, as supplement your knowledge of the MySQL dialect.
Create your SCRIPT file to be named: YourLastName_Project_Ph3.sql.
Step 3: Include the following commands at the tops of your scripts:
SET FOREIGN_KEY_CHECKS=0;
DROP TABLE IF EXISTS STUDENT;
- DROP TABLE IF EXISTS CAMPUS;
DROP TABLE IF EXISTS ROOM;
- DROP TABLE IF EXISTS COURSE;
- DROP TABLE IF EXISTS INSTRUCTOR;
DROP TABLE IF EXISTS APPROVED_INSTRUCTOR;
DROP TABLE IF EXISTS CLASS;
- DROP TABLE IF EXISTS STUDENT_GRADE;
- SET FOREIGN_KEY_CHECKS=1;
- Step 4: Create Tables in your database
- Create a new Table for each of the entities provided to you in the ERD diagram in Step 1.
- Add a column to represent each attribute addressed in the ERD diagram in Step 1.
- Designate Primary Key, as noted in the ERD diagram in Step 1.
- Designate a Foreign Key relationship between the tables, as noted in the ERD diagram in Step 1.
- Enable referential integrity on the relationships, as needed.
- Enable cascade updates as needed on the relationships.
- Step 5: Designate Data Types. Update the data type as needed to enforce the domain constrain of the data. This needs to be completed for every column for all tables.
Dates: they should have a date data designation type.
Surrogate keys: shall be auto-numbered
- Character type: shall have a character data designation type.
- Step 6: Column Constraints Designation.
- Grade designation must be of one of these values as follows: A, B, C, D, E, F, W, E (E=enrolled, and W = withdrawn).
- Student’s first and last names are not to be designated as NULL.
- Course Credit hours shall be BETWEEN one and four.
- The instructor first and last name must NOT be NULL
Course name designation has to be UNIQUE and must not be NULL type.
Step 7: Data Table Addition
- Use the INSERT operator to add minimum 2-3 rows of data per each database.
- You are free to use any values you might like for each of the columns.
- NOTE/ Reminder: you are required to add data to the parent table prior to adding any data to child tables, as referential integrity is enabled.
Step 8: Executing your SCRIPT
Must incorporate the COMMIT command at the end of your Script
- Must incorporate the SHOW TABLES command, to display the table you created. At the end of the script created.
- Must incorporate the SELECT statement to show data allocated for each table. This would be added at the end of the script.
- EXECUTE your SCRIPT.
- Copy and paste your OUTPUT into your MS Word file as follows: YourLastName_Project_Ph3_Output.doc
- Step 9: Upload your work
Upload ZIP file to include the two files as follows: 1) SQL Script with your name as follows: YourLastName_Project_Ph3.sql, and 2) MS Word Document with your OUTPUT, named as follows: YourLastName_Project_Ph3_Output.doc.
