Test & Evaluation Data Archival Repository (TEDAR) – Phase II
TEDAR is an intuitive archival database and interfacing system that will serve as a centralized repository for results from testing and evaluation (T&E), modeling and simulation (M&S), and other analysis events sponsored by Federal agencies and other organizations in large-scale evaluation and analysis of radiation/nuclear (RN) detection instruments and procedures.
The TEDAR will provide a repository for T&E event data, M&S event data, and other analysis event data, consisting of very large amounts of processed and raw structured and unstructured detection device data collected by T&E and M&S events and analyses of these data. Authorized users will be able to search for and access these data collections and retrieve data relevant to their business needs, such as performing engineering analyses and studies.
TEDAR will support a variety of T&E/M&S and analysis data users and provide access to T&E/M&S data sources providing essential support to engineering, acquisition, and operational decision-making. The TEDAR will also provide each data collection and analysis organization a standard interface for sharing T&E data and lessons learned.
The Phase I effort was focused on developing and demonstrating highly innovative solutions to these issues that involve: (1) developing TEDAR such that it is easily customizable to meet the varying needs of a broad range of government and commercial applications; (2) significantly reducing the potential Operations and Maintenance (O&M) costs for a large repository system; (3) providing a very flexible and intuitive interface for the system users; (4) providing an effective and efficient search mechanism via a rich and comprehensive set of metadata that is integrated and linked across the many disparate data collections in the repository; and (5) protecting the T&E/M&S data collections from unauthorized access, change, or corruption.
The Phase II effort will build on the Phase I baseline to complete out the system to an initial product, ready for use by DNDO and to proceed with commercialization. Significant Phase II objectives are to: (1) Improve usability and robustness to a production state, (2) scale up for very large collections and a very large number of collections, (3) design and implement a collection manifest capability; (4) enhance search capabilities; (5) implement support for M&S collections; (6) enhance security; and (7) address commercialization. As required by the SBIR process, these objectives will be addressed over two contiguous 12-month periods. The base capability for DNDO production use will by necessity be addressed in the first 12-month period of Phase II.
A key aspect of Phase II will be standup of a “Beta Test” version of TEDAR for the personnel that DNDO assigns to represent the intended TEDAR user community. These users will be able to access and use the system functionality to become familiar with TEDAR, explore its capabilities, and identify enhancements and added capabilities that are desired. Thus an additional objective for Phase II will be to incorporate user-requested enhancements/functionality as approved by the DNDO system owner within time and resource constraints.
