This paper describes Edition-Based Redefinition (EBR) in the Oracle database --- a novel technology and methodology to build database application patches so that installation of these patches does not require application downtime. It discusses the challenge of zero-downtime application patch installation and shows how EBR can meet the challenge. Customer experience shows that EBR provides online application upgrade in several industries.

Data integration is the process by which data from heterogeneous data sources are conceptually integrated into a single cohesive data set. In recent years agents have been increasingly used in information systems to promote performance. In this work we propose a modeling framework for agent oriented data integration to demonstrate how agents can support this process.

This paper asserts that for databases to manage a significantly greater percentage of the worlds data, managing structural information must get significantly easier. XML technologies provide a widely accepted basis for significant advances in managing data structure. Topics include schema design, evolution, and versioning; managing related applications; and application architecture.
