A more formal approach to Relational Database Management Systems, compared the way they were covered during Web Applications. Database systems are discussed from the physical layer of B-trees and file servers to the abstract layer of relational design. Also includes alternative and generic approaches to database design and database management system including relational, object-relational, and ...

## OSS Speaker Series: The State of the Linux Kernel

Google Tech Talks May 1, 2007 ABSTRACT Andrew will present a broad look at the trends in recent changes in the Linux kernel: what areas of kernel functionality are people working on, and what changes can we expect to see over the next year ? This feature-by-feature walk-through will be tied to an examination of the motivations of the kernel contributors: why do particular individuals and organi...
