Automated Policy-based Asset Cuing Using SQLite

Report No. ARL-TR-5779
Authors: Jesse Kovach and Robert Winkler
Date/Pages: November 2011; 46 pages
Abstract: Unattended assets are being employed in ever-increasing numbers to support current military operations. These assets produce large amounts of data, which is generally handled by presenting it to an operator or analyst for examination. If follow-on actions are required, these actions must be manually initiated by the operator or analyst. Automated asset cuing systems that recommend or initiate follow-on actions by applying policies or rules to incoming sensor data can help reduce the workload on the system operator. This report presents an asset cuing system built around the SQLite database engine that uses the Cursor on Target (CoT) message format to receive sensor data and Structured Query Language (SQL) to express cuing policies. Cuing policies are stored as triggers in the database schema and invoke user-defined functions written in C# to control sensors, robots, unmanned aerial vehicles, and other assets directly from SQL.
