Information
systems engineers, analysts, and developers working within the
Information Sciences Division (ISD) apply their technical expertise to
diverse information-centric efforts, maintaining strong skill sets in
system requirements elicitation, analysis, and management; software
requirements and design methodologies and notations; data base design,
implementation, and administration; client-server and web-based systems
and tools (including development languages and environments); and
network and operating systems configuration and administration.
ISD's
information systems personnel have implemented technologies required for:
-
Data warehousing
-
Data mining
-
Web-based information retrieval and dissemination
-
Technology migration re-engineering
-
Live training simulation
-
Embedded real-time simulation

Products delivered by the ISD Information Systems Analysis team include the
AN/ALE-47 CMDS Software Test Environment (STE). The STE software can simulate
various combinations of naval aircraft and threats in real time in
order to test aircraft mission data files (MDFs) in the computer lab
and correct any errors in the threat response files before deployment.
Each MDF contains complex decision/response data that is critical to the
performance of the threat-response software, which is in turn mission
critical. The MDF must be free of errors. The challenge has been to
devise a cost-efficient way to test the MDFs, removing the risk and
expense of in-flight testing while ensuring that the mission data has
been entered as intended.
Each simulation incorporates genuine ALE-47 hardware components—e.g., the cockpit display unit, dispenser hardware, and/or BOL countermeasures dispenser(s)—and the simulation of other aircraft hardware components through the electrical interface of the Programmer, which automatically selects and executes dispense programs to counter threats, or coordinates the execution of dispense programs manually commanded by the pilot. During simulation, operators are able to capture threat response data for playback and timing analysis.
The Information
Systems Analysis team has also developed innovative information
retrieval techniques, analyzed and improved software development
process alternatives and methodologies, investigated information system
usability, and evaluated emerging technologies for specific application
domains.
