The need to distribute information from localized data bases to remote sites efficiently has become increasingly important. Due to the reaction time constraints, latency on the information must be held to a minimum. A solution is described which will interface wo existing data base equipment and automatically classify from a basis set of information formats, termed "Environmental Data" in the solicitation, and apply an appropriate compression algorithm in response to that determination. The Environmental Data Base Compression (EDAC) applique is transparent to the user and non-intrusive with respect to the existing software, allowing identification and selection of subsets of the information as requested. A system breadboard will be constructed and tested during the Phase I effort to demonstrate the feasibility of the system. This will ideally position Nova for Phase II of this program which will culminate with the delivery of several EDAC engineering units.
