Integrated Database Architecture for Systems Studies in Underwater Acoustics

摘要

An overview of the development of an underwater acoustics database for use in systems studies applications is given. The database is managed by the locally developed Graphical Database Management System (GDBMS). This general purpose database management system has been designed to meet the needs of scientists working with oceanographic data. The important features of the system include the flexibility to handle data in a variety of formats, minimum redundancy storage space, automatic scaling and presentation of data from dissimilar sources (in user specified formats) upon retrieval, and the simple keyword driven operation designed for non-programmer users. Unusual features include the provision for graphical input and output of multi-dimensional data and interfaces to other user computer programs. Examples of several data tables or 'relations' using the GDBMS methods are given. Reference to how the database can be accessed by the Passive Array Sonar Prediction (PASP) code which provides signal excess predictions is also included.
