Information : Oracle Lite
By using Oracle Lite technology and a mobile server environment, the U.S. Army Aviation & Material Command Integrated Materiel Management Center can manage, collect, and store munitions history data without constant connectivity to its server.
One of the functions provided by the U.S. Army Aviation & Missile Command (AMCOM) Integrated Materiel Management Center (IMMC) is to track munitions history. By using two technologies Oracle Lite and a Mobile Server environment constant connectivity to the server is not required. IMMC uses Oracle Lite, an off-line mobile application, for the Ammunition Surveillance Information System-Munitions History Program. Oracle Lite uses data synchronization to reliably and securely exchange data between an IMMC database and the munitions inspectors’ mobile devices (e.g., laptop, Personal Digital Assistant [PDA], etc.). Oracle Lite is an addition to an Oracle database designed for rapid development and deployment of high-impact applications for mobile, embedded, and lightweight environments.
The Mobile Server environment is a three-tier web model that contains a client, a web application server, and a database server. The architecture of the Mobile Server environment (Figure 3-1) contains a mobile client (Oracle Web-to-Go), a mobile server, and a database server (Oracle 9i). The mobile client tier consists of the Oracle Lite database and a laptop/handheld device used to collect munitions history data. The application server tier contains the Mobile Server that processes requests from an inspector and replicates his/her comments and the analyzed data to the database server. The Mobile Server is a module that operates with the Oracle9i Application Server that can run as a component of the Oracle9i Application Server or as a standalone. The database server tier stores the application data (or munitions history data).
