Covers the principles and practice of relational database design and analysis, including topics of entity-relationship modeling, functional dependencies, normalization, relational algebra, as well as their SQL correspondents. Other related issues are discussed such as other data base models, object-oriented database scheme, concurrent data access, recovery and security. One or more projects form a significant part of this course. Falls. Prerequisite(s): CS 2370 and (MA 2200 or MA 3200 or MA2250). 4 Credits
This course is to provide students with a solid background for both theory and practice of computer based information management. To achieve this objective, we study various aspects of (relational) database management systems, particularly, how to design and set up normalized (well organized) databases, how to query (ask questions about) those databases based on relational algebra, how to maintain the integrity of those databases, as well as a detailed discussion of the related conceptual background.
Since database related programming plays an increasingly crucial part in every walk of our lives and works, we also provide an introduction to database programming based on MariaDB, PhP and HTML. If you are interested in more advanced database concepts and programming practice, you may take such subsequent courses as Web programming, Advanced web programming, Mobile applications, HCI, Cybersecurity, Computer Security, Big Data Analytics, and System Administration.
Lectures or other class meetings for this course may be recorded by the university using USNH media platforms. Such recordings may be available for educational use by other students enrolled in the class (including both for instruction and as a review tool), the course instructor(s), and other university officials who support course instruction. Your voice or image may be captured on the recordings, and by enrolling in this course you are consenting to such recording for these purposes.
Students are strongly advised to attend every class. For those who have to miss classes, I have included an extended abstract of my teaching notes within this web based syllabus.
Most of the communication regarding this class will be done through email to your plymouth address, with a subject starting with "CS3600:...", so you have to regularly check your email while taking this course.
Several assignments of homework will be made. Although you should not hand in any homework unless and until you are reasonably sure about their correctness; all the homework must be submitted by the deadline, usually 9 p.m., on the first business day in the following week, once a chapter is completed.
A student should definitely not wait until the last day to do the homework, but get the homework assignment completed right after the relevant subject is discussed.
If you have a solid reason for a delay ("excused absences", as defined in the Plymouth State University attendence policy) of the aforementioned homework and/or project, please let me know before the deadline, or as soon as possible afterwards. The work(s) invovled will not be included in calculating your grade for this course.
To reach a balance of theory and practice, a lab session will be held approximately once a week, usually on Friday from 10:00 a.m. to 10:50 a.m. in Memorial 213. Students are expected to spend a significant amount of time outside the class to go through the labnotes, complete the labworks as assigned within these notes, and send them in by their respective deadline, usually by 10 p.m. on the day it is to be assigned. It is strongly recommended that students read the relevant part(s) before a lab session is to start.
Due to the complexity and magnitude of database programming, teamwork is often the normal format of database related programming. This allows us to further our soft skills such as teamwork, verbal and written communication, time management, problem solving, and
flexibility; and contribute our personal attributes, including risk tolerance, collegiality, patience, work ethic, identification of opportunity, sense of social responsibility, and appreciation for diversity. We thus have also included a semester-long team project with a user friendly interface (UI) and enriching user experience (UX), the outcome of which will be presented at the end of the semester.
If a student finds any part of the assignment, including homework, lab assignment, project assignment, midterm and/or final exam, is not clear, she should ask the instructor for clarification as soon as possible. The instructor will share with the whole class such a clarification, anonymously.
Anything and everything, once submitted, will be considered final. If you send it in prematurely by an accident, please send me an email right away to cancel your submission.
Anything and everything handed in for this course, including homework assignments and the project report, must be readable. You should use, e.g., Notepad++, to type up a text file; and Microsoft Visio for drawing Entity-Relationship charts.
As a constructive feedback, an anonymous sample solution for all the assignments, including homeworks, programming labs, various phases of the team project, and midterm test, will be posted after the event. As a further, and important, step of the learning process, students are urged to study such samplers carefully, and compare them with her own works with the goal of learning what is expected. Please do come to talk to the instructor with any further questions.
Anything and everything handed in for this course must be done by the signed individual, or a group in case of the team project. If enough evidence shows that someone is involved with "cheating", the case(s) will be immediately reported to the leader of the Computer Science and Technology discipline. For relevant definitions and procedural details regarding academic integrity related issues, please refer to the current University's policy on Academic Integrity.
The instructor will try his utmost to be fair in grading students' work as a measurement of the quality of the submitted work in terms of its degree of meeting a clearly stated expectation. On the other hand, if a student believes that s/he is not given a fair grade, s/he should follow the procedure as specified in the University Fairgrading Policy to appeal the grade.

- If this table is not in BCNF, follow the procedure which we just went through in the class, to decompose it into a collection of tables that are in BCNF.
- When you turn the table into BCNF, does it preserve all the FD's? If not, which ones are added and/or dropped?
- Based on the results, revise your database design, populate those tables, and revise the queries that you have come up in Project III, and run them in terms of the revised database.

- A final exam: 8:00 a.m. - 10:30 a.m., Friday, November 20, 2020 (Unit 7--Unit 12), counts (25%)
A calculated grade will then be converted to a letter grade by the following procedure: If a student gets at least 92.5, s/he will get 'A', if s/he gets between 87.5, and 92.4, s/he gets 'A-', so on and so forth, until s/he gets a grade below 42.5, when s/he will get 'F'.
To correct any unintentional inconsistency during the grading process, if your grade is within 0.5 of a letter grade, you will get that higher grade. Thus, if your final grade is above 92.0, you will get A, instead of A-.
As constructive feedbacks for the above items, sample solutions for all the homeworks, projects, and tests, will be posted right after the submission deadline. Besides providing an example of a correct solution to help you achieve the expected learning objectives, such a constructive feedback also serves the purpose of justifying your grade, thus implementing the fair grading policy.
As a critical step of the learning process, each and every student must go through these feedbacks, and ask the instructor for further clarification of any issue(s) s/he might have regarding an assignment, its solution, and the grade that granted for that assignment.
Your final grade for this course can be found here.
