"... Interoperability is more than "digital plumbing"-making sure that computers talk so that bits of data flow properly. Fundamentally, interoperability is people talking and sharing information. Sharing information reduces the "paperwork burden" on the citizen, streamlines work pro ..."

GILS was chosen as a case study so that we can begin to understand how meta-data systems support the construction of interoperable systems. What Are the Benefits of Interoperability? As fourth-generation networked technologies
apis 1 -Automatic Production of Information Systems
"... The objective of the apis research project is to develop a case tool that generates executable information systems (IS) from formal specifications (abstract models). In other words, apis aims at automating as much as possible the production of IS by lifting the level of abstraction at which softwar ..."

DOI 10.1007/s00778-012-0302-x SPECIAL ISSUE PAPER Automating the database schema evolution process
"... Abstract Supporting database schema evolution repre-sents a long-standing challenge of practical and theoretical importance for modern information systems. In this paper, we describe techniques and systems for automating the critical tasks of migrating the database and rewriting the legacy applicati ..."

legacy queries and updates under schema and integrity constraints evolution. The PRISM/PRISM++ approach consists in providing the users with a set of SQL-based Schema Modification Opera-tors (SMOs), which describe how the tables in the old schema are modified into those in the new schema. In order to sup
J2EE Performance and Scalability- From Measuring to Predicting
"... Abstract — J2EE applications are becoming increasingly ubiquitous and with their increasing adoption, performance and scalability issues are gaining in importance. For a J2EE application to perform well and be scalable, both the platform on which it is built and the application design must be effici ..."

on the selected platforms. In this paper, we present a systematic approach for evaluating and predicting the performance and scalability of J2EE applications based on modeling and simulation. The approach helps to identify and eliminate bottlenecks in the application design and ensure that systems are designed

This thesis presents CraneTracker, a multi-modal sensing and communication system for monitoring migratory species at the continental level. By exploiting the robust and extensive cellular infrastructure across the continent, traditional mobile wireless sensor networks can be extended to enable reliable, low-cost monitoring of migratory species. The developed multi-tier architecture yields ecologists with unconventional behavior in-formation not furnished by alternative tracking systems at such a large scale and for a low-cost. The simulation, development and implementation of the CraneTracker soft-ware system is presented. The system is shown effective through multiple proxy deploy-
