1. 25.12.2002Emre Yenier - 98023891 Rethinking Database System Architecture: Towards a Self-tuning RISC-style Database System

2. 25.12.2002Emre Yenier - 98023892 Introduction Current environment –Complex database systems –Numerous functionalities

3. 25.12.2002Emre Yenier - 98023893 Numerous functionalities Complex interfaces High level SQL Unpredictable performance Tuning problems Need for better (thinner) systems Difficulty in researches Problems

4. 25.12.2002Emre Yenier - 98023894 RISC Style Architecture –Smaller, specialized components –Narrow interfaces –Smaller footprints –More suitable for tuning Solution

5. 25.12.2002Emre Yenier - 98023895 Previous Trials Common problem causes –Universality –Cost –Transparency –Resource sharing

6. 25.12.2002Emre Yenier - 98023896 Previous Trials (Cont.) Concepts –DB system generators –Extensible kernel systems –Unbundled technology

7. 25.12.2002Emre Yenier - 98023897 Proposal Query Processor –Single table selection processor –Select – Project – Join (SPJ) processor –SQL Processor

8. 25.12.2002Emre Yenier - 98023898 Proposal (Cont.) Storage Manager –Disk management –Caching –Logging –Recovery –Concurrency control –Index manager

9. 25.12.2002Emre Yenier - 98023899 Considerations Need for more building blocks Avoid complexity Identify functionality Identify interfaces Each block is self-tuning Each block has predictable performance Performance loss is tolerable

10. 25.12.2002Emre Yenier - 980238910 Required Actions Support limited data types Leave SQL Separate resources Preconfigure

11. 25.12.2002Emre Yenier - 980238911 Prerequisites Universal glue Functionality selection Self-tuning

12. 25.12.2002Emre Yenier - 980238912 Research Opportunities Implementation of proposed system

13. 25.12.2002Emre Yenier - 980238913 Conclusion Database systems became uncontrollable RISC style architectures can have impact on the future of database systems
