This course presents the fundamental concepts of database design and use. It provides a study of data models, data description languages, and query facilities including relational algebra and SQL, data normalization, transactions and their properties, physical data organization and indexing, security issues and object databases. It also looks at the new trends in databases, for example, Big Data, MapReduce, and NoSQL. The knowledge of the above topics will be applied in the design and implementation of a database application using a target database management system as part of a semester-long group project.

Honor Code Policy

You can use the following guideline: For homeworks and programming assignments, students are encouraged to consult each other, the TA, the instructor, or anyone else for that matter. However, the assistance offered or accepted should not go beyond a discussion of the problem and a sketch of a solution. You can use the following guideline: when it comes time for you to write your program or your homework paper, do not use any written material from the discussion. If you can reconstruct the discussion and complete the solution on your own, then you have learned the material (and that is the objective of this course!). For team projects, you should make sure to identify division of labor in your README. You are expected to be familiar with and adhere to the University's Academic Honesty Policy.

Late homework and absences from exams

No late submission is allowed. Examinations will be given at alternate times only with appropriately documented medical excuses.
