Project description
Using your Week 1 IP as a starting point, extend the design to accommodate degree programs. The new design should incorporate the following functionalities:

A degree has a name and description.
What degree is the student working towards? A student can only work on one degree at a time.
What classes are necessary to obtain a specific degree?
Provide the DDL script to add the tables for the new design changes. Include an updated diagram that shows all the tables in the system.
Write the DML script to insert 3 test records in each of the tables in the system. This data will be necessary to write the queries in the next assignment.
Copy and paste the work into your Key Assignment document and include screen shots of each step, describe what you did for each step and paste in the actual SQL text used to perform each step. Upload your document to the Submitted Tasks section.

Project description
Reminder: Initial Discussion Board posts due by Wednesday, responses due by Sunday

Students will be expected to post their first initial discussion board posting by Wednesday of each week. Discussion posts will be graded and late submissions will be assigned a late penalty in accordance with the late penalty policy found in the syllabus. NOTE: All submission posting times are based on midnight Central Time.

Students are expected to post their responses to peers by Sunday. NOTE: All submission posting times are based on midnight Central Time.

Primary Task Response: Within the Discussion Board area, write 400600 words that respond to the following questions with your thoughts, ideas, and comments. This will be the foundation for future discussions by your classmates. Be substantive and clear, and use examples to reinforce your ideas:

After designing the base set of tables for the project, the topic of security was brought up. Designing in security at an early stage of the project will make it easier to properly close potential loopholes.

As an example, one type of user is being considered. A class scheduler will be a user who can assign students to classes. He or she can view student and class information but cannot edit that datahe or she can only edit data in the Students_Classes table.

Provide a brief explanation of the SQL server security model. What objects exist?
Explain how those objects available in the security model can be used to implement the class scheduler.
