  2. Welcome • Lab Class • Library 501, Fri 9:00 – 10:40 • Teacher Assistants • 안석현, 이상훈 • {ashworld, sanghoon}@postech.ac.kr • IDS Lab. (279-5878) • Database Systems Lab Homepage • http://ids.postech.ac.kr/dblab2009/

  3. Grading Policy • Midterm 25% + Final 25% • 4 Homework 15% • Participation 5% • Lab / Project 30% • Lab 10% • Minibase project (midterm) 10% • Hadoop(?) project (final) 10% • Your lab assignment will be accepted even after the deadline…But some PENALTY will be given.

  4. Lab Schedule • Introduction • Basic DML • Constraints • Group Functions • Join • Nested Queries • Views • Triggers • Sequences • Indexes • User-defined Functions + Introduction of Minibase or other term projects (This schedule is tentative, and may be sufficiently changeable.)

  5. Project I - Minibase • http://www.cs.wisc.edu/coral/minibase/minibase.html • A tiny DBMS intended for educational use. • It has … • Parser • Optimizer • Buffer pool manager • Storage mechanisms • Heap files, secondary indexes based on B+Tree • Disk space management system • The goal is not just to have a functional DBMS,but to have a DBMS where the individual components can be studied and implemented by students.

  6. Project I - Minibase • We are going to do the project by implementing one or two of these… • Join • B+Tree • Heap Files • Buffer Manager • Disk Space Manager

  7. Project II - Hadoop • One of the Apache projectsfor reliable, scalable, distributed computingincluding … • Hadoop Core • distributed filesystem (HDFS) • MapReduce distributed computing metaphor • Hbase • scalable, distributed database • Pig, ZooKeeper, Hive

  8. Project II - Hadoop • A Simple Inverted Index • PageRank on the Wikipedia Corpus • Clustering the Netflix Movie Data In advance, TAs have to builda Hadoop cluster !!!
