Course Description

Official Calendar: Databases from a user's perspective: querying with SQL, designing with UML, and using programs to analyze data. Construction of database-driven applications and websites and experience with current database technologies. Completion of COSC 121 is recommended. Prerequisite: One of COSC 111, COSC 123, COSC 210. Third-year standing.

Specific description: This course provides an introduction to database systems including database querying, design, and programming. The course consists of three major components. The first component explains databases from a user perspective including how to query using SQL and relational algebra. The second component involves designing relational databases using Entity-Relationship (ER) diagrams and UML. The last part involves database and web programming with Java, JDBC, JSP, Python, and PHP. Students completing the course have experience with current database technologies, and the ability to use and develop databases and associated applications.

Course Objectives

Course Format: Interactive online classes consisting of topic introduction, understanding evaluation using quick questions, and concept mastery with larger exercises. Practical skills and applications of topics covered in assignments as well as practice using industrial database systems and software.

Learning Outcomes:

● Understand the use case for databases and the relational model for data storage. 

● Proficiency in creating queries on relational databases using relational algebra and SQL.

● Read existing database designs, design new databases using ER/UML modeling, and convert to the relational model.

● Construct programs that access a database to read data, perform analysis, and output results.

● Exposure to database technologies like NoSQL, JSON, XML, and cloud databases.

Grading Practices

Faculties, departments, and schools reserve the right to scale grades in order to maintain equity among sections and conformity to University, faculty, department, or school norms. Students should therefore note that an unofficial grade given by an instructor might be changed by the faculty, department, or school. Grades are not official until they appear on a student's academic record. http://www.calendar.ubc.ca/okanagan/index.cfm?tree=3,41,90,1014

Missing an Exam

Only students who miss the final exam for a reason that corresponds to the University of British Columbia Okanagan's policy on excused absences from examinations will be permitted to take the final exam at a later time. A make-up exam may have a question format different from the regular exam. There will be no make-up midterm exams. If the reason for absence is satisfactory, the student’s final exam will be worth more of the final grade. Further information on Academic Concession is in the Academic Calendar http://www.calendar.ubc.ca/okanagan/index.cfm?tree=3,48,0,0.

Final Examinations

The examination period for S2021 T- 2 is August 16 – 20, 2021. Except in the case of examination clashes and hardships (three or more formal examinations scheduled within a 24-hour period) or unforeseen events, students will be permitted to apply for out-of-time final examinations only if they are representing the University, the province, or the country in a competition or performance; serving in the Canadian military; observing a religious rite; working to support themselves or their family; or caring for a family member. Unforeseen events include (but may not be limited to) the following: ill health or other personal challenges that arise during a term and changes in the requirements of an ongoing job. Further information on Academic Concession can be found under Policies and Regulation in the Okanagan Academic Calendar http://www.calendar.ubc.ca/okanagan/index.cfm?tree=3,48,0,0

Grievances and Complaints Procedures

A student who has a complaint related to this course should follow the procedures summarized below:

● The student should attempt to resolve the matter with the instructor first. Students may talk first to someone other than the instructor if they do not feel, for whatever reason, that they can directly approach the instructor.

● If the complaint is not resolved to the student's satisfaction, the student should e-mail the Associate Head, Dr. Yves Lucet at [email protected] or the Department Head pro tem, Dr. Andrew Jirasek at [email protected]

Your Responsibilities

Your responsibilities to this class and to your education as a whole include attendance and participation. You have a responsibility to help create a classroom environment where all may learn. At the most basic level, this means you will respect the other members of the class and the instructor and treat them with the courtesy you hope to receive in return. Inappropriate classroom behavior may include: disruption of the classroom atmosphere, engaging in non-class activities, talking on a cell-phone, inappropriate use of profanity in classroom discussion, use of abusive or disrespectful language toward the instructor, a student in the class, or about other individuals or groups.

Academic Integrity

The academic enterprise is founded on honesty, civility, and integrity. As members of this enterprise, all students are expected to know, understand, and follow the codes of conduct regarding academic integrity. At the most basic level, this means submitting only original work done by you and acknowledging all sources of information or ideas and attributing them to others as required. This also means you should not cheat, copy, or mislead others about what is your work. Violations of academic integrity (i.e., misconduct) lead to the breakdown of the academic enterprise, and therefore serious consequences arise and harsh sanctions are imposed. For example, incidences of plagiarism or cheating may result in a mark of zero on the assignment or exam and more serious consequences may apply if the matter is referred to the President’s Advisory Committee on Student Discipline. Careful records are kept in order to monitor and prevent recurrences. A more detailed description of academic integrity, including the policies and procedures, may be found: http://okanagan.students.ubc.ca/calendar/index.cfm?tree=3,54,111,0 If you have any questions about how academic integrity applies to this course, please consult with your professor.
