CS 471000 Introduction to Database Systems

Implementation, architectural design, and trade-offs.


This course provides an overview of the current database management systems in the cloud, and explains how they are different from traditional database systems. The goal is to get students familiar with some well-known implementations like NoSQL databases, Google BigTable, Google MegaStore, and Google Spanner etc., and more importantly, to help students make better decisions on the design tradeoffs when configuring/building their own database systems given a particular set of target applications (tenants) in mind.

Proper understanding of Java/OOP programming and data structure is required.
