CS 448 Database Systems Implementation


Watch a video introduction to this course on YouTube.

Objectives

The objective of this course is to introduce students to fundamentals of building a database management system (DBMS), in particular a relational one. It focuses on the database engine core technology by studying topics such as storage systems (data layout, disk-based data structures), indexing, query processing algorithms, query optimization, transactional concurrency control, logging and recovery. It complements CS348 by looking at the internals of relational DBMSs.

Intended Audience

This is a second course on databases that focuses on DBMS internals. It is a project-oriented course that will provide the students, upon successful completion, with an appreciation of the intricacies and complexities of a DBMS and enable them to be able to design and implement the major components of it. The course objective will be achieved by focusing on three fundamental sub-objectives:

  1. To understand the fundamentals of storage systems and disk-based data structures;
  2. To understand the process of query processing and optimization; and
  3. To learn the implementation of transactions.

Complementary to the above objectives, the course has a training component where the students will gain experience, within the context of a number of assignments, in building components of a DBMS and incorporating them into an open source system such as MySQL or PostgreSQL. The lectures may be complemented by guest lectures on real-life DBMS implementation issues given by colleagues from industry (Sybase, IBM Canada, Microsoft and others).

CS 448 is a course for CS major students, and is normally taken in a student's fourth year. This course will be of interest to students whose area of expertise includes large software systems. CS 338 is available for students in other plans.
