摘要

To satisfy the database management needs of a generic meteorological andoceanographic nowcasting workstation, a software system based on a set of design guidelines derived from today's and future data processing requirements was developed. This software system consists of a set of generic database management tools that handle the current and anticipated future. geophysical data sets, unify the data access interface protocols, provide data ingest/export utilities, and support database inventory browsing functions. Currently, the system handles geostationary and polar orbiting satellite image data, numerical weather and ocean prediction and model output, climatological and geographic data, terrain and bathymetric data, and conventional as well as satellite observations. This system is called Naval Environmental Operational Nowcasting System (NEONS). The obvious difference between the NEONS approach and other environmental database management system is the employment of a commercial relational database management system (DBMS) to perform the actual data query, access, and routine database management operations. However, there is also a fundamental difference in he system design whereby NEONS uses the generic data type approach and mainly manages the attributes of data sets. This approach presents a high-level logical view of diverse environmental data sets to users, optimizes the data retrieval efficiency, and insulates the applications programs from the commercial computer hardware and software. As a result, NEONS is readily portable to a variety of UNIX computer workstations and mainframes.
