MAIN PRESENTATION
-----------------
Topic: Relational Database Management System (RDBMS) Internals
Introduction & Description of Talk:
-----------------------------------
This will be a highly technical talk on the inner workings of a
modern relation database engine both from a theoretical point of
view and a practical one. Implementations that exist in existing
systems will be discussed, in addition to why certain theoretically
possible systems were never implemented. There will be a heavy
focus on issues of transaction processing (ACID) and a discussion
of how the "relational" (SQL) portions of a system are implemented.
We will cover the history of these systems and discuss concrete
implementations of real world systems.
Detailed Outline:
-----------------
- History:
- Pre Relational Systems
- The Early Relational Systems and Why They Became So Dominant.
- The Lineage of our Modern Day Systems.
- Detailed Exposure of Internals:
- Buffer Pool
- Logging
- Concurrency Control
- BTrees
- Query Planner
- Analysis of 3 Existing Systems:
- DB2
- Oracle
- PostgreSQL
- Observations on Current Trends and Predictions on Future Directions.

Speaker Biography:
------------------
Alex Scotti is the original author and current head of a team
focusing on the development of the Comdb2 relational database
system. Under active development for 10 years, Comdb2 is the
database that backs the majority of customer facing Bloomberg
applications. Alex has a solid understanding of both the
theoretical underpinnings of database systems, and the practical
issues of implementation and tradeoffs in both the Comdb2 system
and most existing systems.
-------------------------------------------------------------------
Company Biography:
------------------
Bloomberg, the global business and financial information and news
leader, gives influential decision makers a critical edge by
connecting them to a dynamic network of information, people and
ideas. The company's strength "delivering data, news and analytics
through innovative technology, quickly and accurately" is at the
core of the Bloomberg Professional service, which provides real
time financial information to more than 310,000 subscribers
globally. Bloomberg's enterprise solutions build on the company's
core strength, leveraging technology to allow customers to access,
integrate, distribute and manage data and information across
organizations more efficiently and effectively.
Through Bloomberg Law, Bloomberg Government, Bloomberg New Energy
Finance and BNA, the company provides data, news and analytics to
decision makers in industries beyond finance. And Bloomberg News,
delivered through the Bloomberg Professional service, television,
radio, mobile, the Internet and two magazines, Bloomberg

than 2,300 news and multimedia professionals at 146 bureaus in 72
countries. Headquartered in New York, Bloomberg employs more than
15,000 people in 192 locations around the world.
-------------------------------------------------------------------
Giveaways:
----------
Addison-Wesley Professional/Prentice Hall PTR, and O'Reilly have
been kind enough to provide us with review copies of some of their
books, which we will continue to raffle off as giveaways at our
meetings. The publishers always ask that the persons receiving
the books provide a review and/or feedback about their books.
Unigroup would like to thank both companies for the support
provided by their User Group programs.
As always, all of the books will be available for review at the
start of the meeting.
Note: Our supply of books is low right now, we hope to resolve
that soon.
-------------------------------------------------------------------
Fee Schedule:
-------------
Unigroup is a Professional Technical Organization and User Group,
and its members pay a yearly membership fee. For Unigroup members,
there is usually no additional charges (ie. no meeting fees) during
their membership year. Non-members who wish to attend Unigroup
meetings are usually required to pay a "Single Meeting Fee".
Yearly Membership (includes all meetings): $ 50.00
Student Yearly Membership (with current! ID): $ 25.00
Non-Member Single Meeting Fee: $ 20.00
Non-Member Student Single Meeting (with! ID): $ 5.00
* Payment Methods: Cash, Check, American Express.
! Students: We are looking for proof that you are
currently enrolled in classes (rather than working
full-time), and as such, your Student ID should show
a CURRENT date. We have been presented Student IDs
containing NO dates whatsoever, and in the
current environment, perpetual/non-expiring access
to university facilities just does not feel right.
If your ID contains no date, please bring
additional proof of current enrollment. Thanks,
NOTE: Simply receiving Unigroup Email Announcements does
NOT indicate membership in Unigroup.
Members: Remember to bring your Unigroup membership card with
you to the meeting, to confirm your yearly renewal date!
