  1. TTA Project THEORACTICE OCT. 25, 2005

  2. Project Overview 1) Have you ever used DBMS such as Oracle, MS-SQL ? 2) How can you decide whether the DB performance is good or not?

  3. Project Overview TPC-H based DB Performance measuring tool De facto industry standards body for OLTP ● Examining large amounts of data ● Examining queries that are complex ● Essential Metrics 1) Time to load the database 2) Queries per Hours (QphH) 3) Price / performance ($ / QphH)

  4. Context Diagram (Overall)

  5. Divide Sub-problems 1) Database Generator 2) Database Query Generator 3) Measure Metrics based on TPC-H 4) Report measured results

  6. Sub problem-1 (Create DB)

  7. Sub problem-2 (Create Query)

  8. Sub problem-3 (Analyze Result)

  9. Sub problem-4 (Show Report)

  10. Major Question ? How can we map sub-problems to problem frames ? Given problem frames are enough ?
