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.

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.

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.
We have some Solaris Related CD-ROMs from our friends at the local NYC Sun Microsystems Office.
(Note: Our supply of books is low right now, we hope to resolve that soon.)
