Figure 30 illustrates the IDBMS concept, which shows the 

 integration of spatial and temporal modeling, forecast and 

 performance modeling, and decision support modeling. For the 

 Navy's operational use, these data and modeling capabilities 

 are used to develop specific products, such as sonar system 

 performance. However, IDBMS also could be used to extract 

 data and model results having scientific utility— the very data 

 that has been the subject of much of this report. 



The information and data in IDBMS are located in a series of 

 IDBMS gateways on both a classified and an unclassified 

 network. Those gateways on the network contain information 

 such as gravity, bathymetry, geomagnetics, and acoustic data, 

 as well as oceanographic projects, satellite processing. 



physical oceanography data, and performance tools. Access 

 to the infonnation is made available to users on workstations. 



The user is directed through the process of DBMS access 

 through a main menu, with top-level functions made available 

 for tools (accessing tools directly), catalogs (browsing), 

 locations (global overview map), queries (searching for inform- 

 ation), and help. 



Categories of measured IDBMS data are shown in Table 10. 

 Table 1 1 illustrates sample categories of gridded/provinced 

 IDBMS data. Both types of data can be accessed from wi Jiin 

 IDBMS; however, the applications, models, and tools within 

 IDBMS may use either one type of data or various combina- 

 tions of both.
