Real World Problem #1 "Sub Hunt"
Where did the submarine go?

The problem is to be able to track a single sub in the ocean of information coming from the undersea passive sonar network. This network produces sample records at a rate of 10,000 every 2 seconds, consisting of 64 16-bit numbers (FFT), a location, and a time/date stamp. This large volume of data must somehow be stored in a database. The database must then be able to find all of the records within a time range that have soft matches to a target FFT. This output set must then be displayed as a track on a map. This answers the question. Where did this sub go?

This problem can be solved by using MPbase. Although this is a complex data problem, it a simple information problem. MPbase's combination of internal characteristics make easy work of this task.

First, the multidimensional hypercube nature of MPbase allows the relevant data to be logically located near each other in all of the 66 dimensions (64 numbers, location and time). This entire database would need to be stored in only one MPbase table.

Second, the content-addressable memory (CAM) nature of MPbase will cause all of the records with similar FFTs to be stored near each other in the hypercube.

Third, MPbase's ability to do a soft match makes locating the needed FFTs a simple task. This can be further enhanced with the addition of custom match or analysis routines. These routines can be used to augment and/or replace MPbase's own internal routines.

Fourth, the massively parallel architecture allows for the sheer volume of updates that such a database will need to accept. MPbase has no special "data load" function. None is needed. All data placed in MPbase goes through the update cycle with no performance penalty. As a mater of fact, the more updates MPbase has to process the more efficiently it does so. The farther behind it gets, the more quickly it will catch up.

Fifth, data in MPbase is internally compressed to a very high level. This, coupled with the parallel nature, allows all of the needed performance to do this task in real-time.

Sixth, the relational nature and formatting functionality in the output view allows MPbase to provide the result set in any needed format. This could directly feed a GIS system or even a CAD program to graphically display the sub's track.

Seventh, the fault-tolerant nature of MPbase provides the kind of reliability such a system must have. If enough hardware remains to run a query, MPbase will continue to function

In short, with MPbase this nasty real world problem is no problem.
