ABSTRACT
Over recent years, "Internet-able" applications have been used to support domains
where distributed functionality is essential. This flexibility is also
pertinent in situations where data is collected and derived to support
a distributed set of stakeholders. There are major problems in this
distributed data management scenario. One problem is the change that
occurs in such domains. Both the schema of the data and the individual
needs of the stakeholders evolve over time. Any architecture to support
this distributed data management domain must be designed to support
these specific changes. One such approach to this architecture is the
use of "plug-able" web-based components. As new computational needs
arise, new components can be plugged into the architecture. Another
aspect of this solution architecture is toward a run-time evolvable
process to support the change of the data schemas. At The MITRE Corporation,
this architecture has been designed, deployed, and tested to support
the internal need for a composite data repository. This paper presents the motivation and architecture of this distributed data management system that supports the Center for Advanced Aviation System Development (CAASD). This component-based
run-time configurable architecture is implemented using web-based technologies, such as the Extensible Markup Language (XML), Java Servlets, and a relational database management system (RDBMS).
