PRESENTATION OUTLINE
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.
