New technology is always evolving and companies must have appropriate security for their businesses to be able to keep up to date with the changes. With the rapid growth of the internet and the world wide web, data and applications security will always be a key topic in industry as well as in the public sector, and has implications for the whole of society. Data and Applications Security covers issues related to security and privacy of information in a wide range of applications, including: * Electronic Commerce, XML and Web Security; * Workflow Security and Role-based Access Control; * Distributed Objects and Component Security; * Inference Problem, Data Mining and Intrusion Detection; * Language and SQL Security; * Security Architectures and Frameworks; * Federated and Distributed Systems Security; * Encryption, Authentication and Security Policies. This book contains papers and panel discussions from the Fourteenth Annual Working Conference on Database Security, which is part of the Database Security: Status and Prospects conference series sponsored by the International Federation for Information Processing (IFIP).The conference was held in Schoorl, The Netherlands in August 2000.

Multimedia Database Management Systems brings together in one place important contributions and up-to-date research results in this important area. Multimedia Database Management Systems serves as an excellent reference, providing insight into some of the most important research issues in the field.

Multimedia Database Systems: Design and Implementation Strategies is a compendium of the state-of-the-art research and development work pertaining to the problems and issues in the design and development of multimedia database systems. The chapters in the book are developed from presentations given at previous meetings of the International Workshop on Multi-Media Data Base Management Systems (IW-MMDBMS), and address the following issues: development of adequate multimedia database models, design of multimedia database query and retrieval languages, design of indexing and organization techniques, development of efficient and reliable storage models, development of efficient and dependable retrieval and delivery strategies, and development of flexible, adaptive, and reliable presentation techniques.

The intrusion of the Internet drastically modified the historical cycles of communication between authors, providers and users. Today, information is often the result of the interaction between data and the knowledge based on their comprehension, interpretation and prediction. Nowadays important goals involve the exchange of heterogeneous information, as many real life and even specific scientific and technological problems are all interdisciplinary by nature. For a specific project, this signifies extracting information, data and even knowledge from many different sources that must be addressed by interoperable programs. Another important challenge is that of corporations collaborating with each other and forming coalitions and partnerships. One development towards achieving this challenge is organizational hubs. This concept is new and still evolving. Much like an airport hub serving air traffic needs, organizational hubs are central platforms that provide information and collaboration specific to a group of users' needs. Now companies are creating hubs particular to certain types of industries. The users of hubs are seen as communities for which all related information is directly available without further searching efforts and often with value-added services.
