The emergence of Web databases has introduced new challenges related to their organization, access, integration, and interoperability. New approaches and techniques are needed to provide across-the-board transparency for accessing and manipulating Web databases irrespective of their data models, platforms, locations, or systems. In meeting these needs, it is necessary to build a middleware infrastructure to support flexible tools for information space organization, communication facilities, information discovery, content description, and assembly of data from heterogeneous sources. In this paper, we describe a scalable middleware for efficient data and application access that we have built using the available technologies. The resulting system is called WebFINDIT. It is a scalable and uniform infrastructure for locating and accessing heterogeneous and autonomous databases and applications.

The ubiquity of the World Wide Web facilitates the deployment of highly distributed applications. The emergence of Web databases and applications has introduced new challenges related to their organization, access, integration, and interoperability. We present a dynamic architecture and system for describing, locating, and accessing data from Web databases and applications. We describe a scalable middleware for efficient data and application access that we have built using the available technologies. The resulting system is called WebFINDIT. It is a scalable and uniform infrastructure for accessing heterogeneous and autonomous databases and applications.

The Web

With the emergence of the Web, there is a need to provide across-the-board transparency for accessing and manipulating data irrespective of platforms, locations, and systems. The challenge is to build an infrastructure to support flexible tools for information space organization, communication facilities, information discovery, content description, and assembly of data from heterogeneous sources. In this chapter, we describe the WebFINDIT system. WebFINDIT builds a scalable and uniform infrastructure for locating and accessing heterogeneous and autonomous databases in large and dynamic environments. One key feature of WebFINDIT is the clustering of Web databases into distributed ontologies. The main advantage of this ontological organization is filtering interactions and reducing the overhead of locating information. Another important feature is the large spectrum of heterogeneity being supported. Heterogeneity appears at different levels, including hardware (Sun and NT), operating system (UNIX and NT), database (Oracle, Informix, DB2, ObjectStore), and communication middleware (CORBA, DCOM, EJB, and RMI).

Government accountability is important for more rational and effective functioning of authorities and societies. The actual assessment of government performance in the present complex and diverse socio-economic realities is not possible without qualitative and quantitative analyses. Additionally, new approaches and methods in synchronization with ICTs, computer simulations, and modeling enable the improvement of execution of the governments. This chapter advocates that multicriterial and multilevel assessment of governments should be enriched by recognition and analyses of contexts in which they act. Government characteristics and the present contexts are diverse and their responses to new challenges are limited and differentiated.
