  1. A protocol for evaluating an OODBMS Master thesis in Computer Science Anders Carlsson

  2. Introduction • Databases are central parts of todays computer and software systems. • Explore what are the features of the system that influence the choice of system.

  3. Problem description • Many different OODBMS available. • Wide range of functionality on different systems. • Lack of time to evaluate many systems. • => • A method for faster system evaluation is needed.

  4. Research questions • What features are important when selecting which object oriented database management system to use? • How important are these features compared to each other?

  5. Goal: Protocol Is to be used when evaluating an OODBMS. Describes… • …what features are important. • …how important the features are.

  6. Research process • Preliminary activities • Literature study • Interviews • Survey on DBMS • Survey on OODBMS • Protocol elaboration • Evaluation of the results

  7. Literature survey • Goal: Deepen the understanding of database management systems. • Books and databases at the Infocenter. • Papers and articles on the Internet.

  8. Interviews • Goal: Verify the correctness of the results from the literature survey. • Two database administrators. • One system developer. • One person - both DBA and developer. • Three students at BTH.

  9. Survey on DBMS • Goal: Verify earlier results and give a rate on how important the features are. • Web based. • Sent out to 134 companies, 123 in IT-business.

  10. Survey on OODBMS • Goal: Verify earlier results and give a rate on how important the features are. • Web based. • Sent out to four people with experience on working with OODBMS.

  11. Results • List of mandatory features for an OODBMS. • List of features not mandatory, with rating on importance. • Protocol for evaluation of an OODBMS. • Guideline on how to use and compare results.

  12. Protocol • Containes a description of how to perform a certain task. • Includes information on how to use results from protocol implementation. • Some parts are fixed and some open.

  13. Reliability: Feature list • Very reliable. • Compound from a wide range of literature and empirical data from the industry.

  14. Reliability: Importance rate • People involved in answering the surveys have experience on working with databases for at least 5 years. • Reliability could be improved by… • …gathering more answers to survey than is the case now. • …perform new interviews regarding the found rate.

  15. Validity • Valid only for guidance in selecting systems for further investigation. • The protocol is not a complete evaluation tool. • Lack of statistical support for importance rating.

  16. Future work • Increase reliability of importance rating; conduct new surveys. • Evaluate a number of systems according to the protocol to get empirical data on its validity.
