Introduction to Data Management

Description: In this course, we will introduce the basics of modern data management. You will learn about schema design, data modeling, query languages, building database applications, transactions, and many other topics. Through lectures, sections, and assignments, you will learn about and understand how real-world data management systems work, and how they touch upon many aspects of our daily lives.

Remote quarter: This quarter is mandated to have fully online instruction with no in-person meetings permitted. So long as the staff internet connections permit, we will still be holding synchronous lecture/section meetings so that students have the opportunity to ask questions and work together - please do attend and participate! The class Canvas holds our full Zoom schedule. Lecture recordings will be posted if you need to access them asynchronously.

Questions and Comments: If you have any questions or comments about lectures, sections, assignments, quizzes, or whatever, post on ED. This is the fastest way to get in contact with the 344 staff and your peers. You can post privately to just the staff and anonymously to the whole class if you want to. If you need to talk about anything personal or offline, see us during office hours or email the instructor (ajratner @ cs) to set up a meeting. And we love feedback! If you have any concerns, comments, or suggestions let us know through this anonymous feedback tool or feel free to contact us directly.

For additional details about the class, please refer to the syllabus.
