Common Data Access Models and Services Using Datalets

"Due to the large number and variety of data storage and access technologies, as well as the need for analysts and programmers to understand data schemas and how they relate to the application domain, development of data-intensive software is a laboriousoperation. This presents the challenging problem of enabling access to these data sources via a common data access model and services. In this approach, all data conforms to a single data access model and a single API is used to provide data accessservices.Architecture Technology Corporation has developed a design for a common data access model and services utilizing the datalets concept and its associated ontology. This project will develop and test a prototype implementation of the datalets architecture.The research will leverage state-of-the-art technologies such as various XML protocols and agent-based programming. The resulting universal data access framework will be tested in the context of Air Mobility Command applications. The effort will becompatible with the overall approach of the "Joint Battlespace Infosphere (JBI)" research program."
