Teaching Fellow: Spencer S Pearson
Time: MWF 9:30 am - 10:20 am
This graduate course provides an introduction to the design and development of fundemental concepts in relational database management systems (DBMS). You will learn the theory behind database systems, the issues that affect their functionality and performance, and most importantly, what it takes to build the engine of a relational database management system and to explore the role of modern data processing platforms, e.g., Apache Spark/Hadoop. There is a significant component of Java/SQL/Scala development. There will also be hands-on exercises using the Oracle DBMS and Spark/Hadoop/HDFS. The list of topics covered in this course includes:
- DBMS Concepts and Architecture
- Relational Databases, Relational Algebra and Calculus
- Query Languages (SQL)
- Storage and Indexing
- Query Evaluation and Optimization
- Database Design, the E-R Model, Normalization, and Tuning
- Database Security
- Management, Concurrency Control, and Recovery
- Parallel and Distributed Databases
- New Trends in Data Systems (e.g., NoSQL Databases)

Workload:There will be around four-five programming assignments. In each assignment, you will be asked to implement one component of a simple database management system. There will be an SQL programming assignment using Oracle. There will be around three homeworks, a final project, and a final exam.
In the final project, you will be asked to implement your favorite optimization strategies to improve query execution on Spark and/or Hadoop platforms. Additionally, you are required to submit a report that describes the employed techniques, evaluation methodology, and experimental results.
Programming Assignment:The programming assignments are an important part of the course, and will involve a significant amount of Java programming. The first programming assignment will be SQL programming assignments using Oracle. The remaining assignments will be performed in teams of two. The purpose is for each team to build parts of a working single-user relational database management system. You will start almost from scratch -- a few basic components may be provided to you. By the end of the course, you will have built a simple DBMS by completing four separate assignments. In most of the assignments, you will be given Java class definitions with templates. You will need to actually implement the functions. Implementing the various interfaces involves several hundred lines of code. At the end of the programming assignments, you will understand the basic relational DBMS concepts because you have implemented them. Each of your assignments builds upon the code written in the previous assignments.
Unless extremely necessary, you should not change partners for programming assignments. You need to have the instructor’s prior approval to switch partners.
Final Project:The final project is a crucial part of the course that prepares to undertake a small research project on modern database systems. It will provide an opportunity for you to apply the lessons that your learned throughout the course to a research problem of your choice. Thus, the final project is open-ended, but, it must* contain the following core elements:
- studying and comparing the performance of Hadoop and Spark based on a standard database benchmark (TPC-H or BigBench) in order to understand the role of disk vs. main memory for query performance
- exploring different query processing strategies over Spark and/or Hadoop (such as data partitioning/replication, materialized view, join reordering, and index selection)
- writing a detailed (but concise) report that describes your approach, evaluation methodology, and experimental results (i.e., similar to a short research paper).
You may start your final project at anytime (it is recommened that you start as early as possible). The report for the final project is due on December 1, 2016.
*You may discuss with the instructor the opportunity to propose an alternative final project that is directly related to modern database systems. You need to have the instructor’s prior approval before start working on your own-defined final project proposal.
Grading (tentative):The final grade will be based upon the following:
- Homework Assignments: 20%
- Programming Assignments: 30%
- Final Project: 20%
- Final Exam: 30%
(Extra-credit can be earned in the final project)
Course Policy:In this class, we adopt the following policy: http://spaf.cerias.purdue.edu/cpolicy.html
In addition, late submission will result in a 10% penalty for each day late. Students are strongly advised that any act of cheating will result in a score of 0 for the entire assignment and repeat offences will be reported to the Office of the Dean of Students and will result in an automatic F grade. You are encouraged to discuss problems and ideas but the final solution or code must be your own. In the event of a major campus emergency, course requirements, deadlines, and grading percentages are subject to changes that may be necessitated by a revised semester calendar. If such unusual circumstances arise, students may determine any such changes by contacting me via email ([email protected]).
