Introduction

The UCB team is tasked with coordinating the implementation details between participating groups. Therefore, we have a hand in each aspect of the EOSDIS end to end problem mentioned in our parent page. Without going into every detail, we can summarize major efforts as follows:

1. Prototyping
2. Data collection
3. Architecting an interface

In addition, we are exploring several areas of research that are inherent in such a DBMS-centric architecture. These include:

1. More effective wide-area distributed-DBMS technology. Our efforts focus on a prototype distributed DBMS, called Mariposa.
2. A type library for optimally regridding satellite imagery (David Siegel).
3. An advanced visualization system for specifying user interactions with the database known as Tecate, headed by Peter Kochevar.
4. A more effective interface between a DBMS and a tertiary memory file system . This is a part of the High Performance Storage System Project, HPSS , headed by Dick Watson. Also see the National Storage Laboratory, NSL.
5. End-to-end modelling of the "end-to-end" problem of going from data source to DBMS to visualization system. The " Gator " project has as its goal to identify the ultimate bottlenecks in the overall architecture and then focus on parallelization of these modules. Gator is headed by Jim Demmel.
6. A more flexible wide-area networking protocol, headed by Joseph Pasquale.
