An Overview of the InterBase System

Distributed, heterogeneous, and autonomous hardware and software systems are the product of lengthy and diverse computational and information processing requirements. The introduction of harmonious cooperation among such systems carries the potential for great increases in productivity and improvement in applications processing. However, such a harmonious cooperation must be supported by an integrated system that would allow the development of global applications. The InterBase System is such a system. It integrates pre-existing systems over a distributed, autonomous, and heterogeneous environment to support global applications while retaining local autonomy. This paper gives a high-level description of the InterBase System. 1 Introduction Today's computing environments in most organizations consist of distributed, heterogeneous, and autonomous hardware and software systems. The distribution of these systems reflects the diverse nature of modern business, where heterogeneity ..

Nasa global change master directory: an implementation of asynchronous management protocol in a heterogeneous distributed environment

The Global Change Master Directory (GCMD) is an earth science repository that specifically tracks research data on global climatic change. The GCMD is migrating from a centralized architecture to a globally distributed replicated heterogeneous federated system. One of the greatest challenges facing database research is the integration of heterogeneous systems without compromising the local autonomy, reliability and transparency of the various databases that are participating in the integration. This paper discusses these challenges in the context of the design and implementation of the next version of the GCMD software (Version 8.0). The proposed system has been designed and developed using an object-oriented system architecture based on Java, RMI (Remote Method Invocation) and JDBC. This system enables other sources to be integrated into the GCMD system, with limited changes to the local system itself. This paper describes the components of the GCMD system and addresses the issues of heterogeneity, distribution and autonomy. Keywords

Support for real-time decision making in mobile financial applications

Mobile users making real-time decisions based on current information need confidence about their context been taken into consideration in producing recommendations. This chapter reviews current use of mobile technologies for decision support. Specifically, it describes a framework for assessing the impact of mobility in decision-making. The framework uses dynamic context representation of data quality to represent uncertainties in the mobile computing environment. This framework can be used for developing visual interactive displays for communicating to the user relevant changes in data quality when working in mobile environment. As an illustration, this chapter proposes a real-time decision support procedure that aims at providing on-the-spot assistance to the mobile consumer when choosing the best payment option to efficiently manage the user’s budget. The proposed procedure is based on multi-attribute decision analysis, scenario reasoning and a quality of data framework. Feasibility of the approach is demonstrated with a mobile decision support system prototype implementation
