Common Data Access Models and Services

We propose to develop an intelligent self-reorganizing middleware providing access services that are independent of data sources and that provide a common simultaneous access for various clients running on multiple platforms. Presented below are (1) thetechnology, (2) the killer application, (3) highlights of a B-Plan and (4) Phase I work plan. This project will utilize the Java-based Nodes API (NAPI) technology, which is a highly efficient object-access technology managing 4-layered caching mechanism.NAPI is unique in that it anticipates which objects that are likely to be requested, and pushes these objects through the cache pipeline; it is asynchronous, thus enable populating the cache pipeline through background processes while deliveringinstantaneous client response. The proposed killer application presents an opportunity to overhaul of the current casualty reporting system and redefine the acquisition and distribution of medical situations and needs; it will be designed with a focus onultra-fast response for effective crisis management.NAPI was successfully used to implement diverse application such as a knowledge visualization tool, and a patient record abstraction and visualization tool. In this project, NAPI will be extended to support Office Automation (OA) tools and email client.NAPI has the potential of simultaneously reducing the development costs and improving the performance of applications that require access to persistence object storage through a middleware component. This potential can be realized through the integrationwith leading application servers, such as WebSphere (IBM) and WebLogic (BEA Systems).
