Developing Mobile Applications within an Enterprise Architecture CASE STUDY Deputy Under Secretary of Defense (OUSD) Military Community & Family Policy (MC&FP) Military Installations Mobile Application By: Robin Parrish – eSpatial Inc – VP Business Development Matt Bafford - eSpatial Inc – Senior Consultant
Presentation Outline Military Installation Requirements Application Components –Demo of Desktop Application The Enterprise Architecture Mobile Development Approach Examples of Mobile Application Conclusion –Value of the Enterprise Architecture
MilitaryINSTALLATIONS Requirements Deliver a user friendly GUI with Google Maps like functionality Pan/Zoom, ToolTips, Interactive GeoCode existing address of base level services as defined by DoDITC Enable geospatial searches for base level services Easy of Use –Hide traditional GIS complexity from end users Display and query “ Nearby ” Points of Interest Data Route between base level services and POI ’ s Extend and use existing Oracle DB platform Storage and analysis of geospatial data in Oracle Spatial Implementing the Oracle LBS API for routing Support service personnel on travel via mobile devices
Application Components Integrated through the MilitaryHOMEFRONT Oracle Portal –Standard web browser application Oracle 10g Database and Application Server Oracle Spatial with LBS API eSpatial ’ s iSMART development framework NAVTEQ Data Real-time Custom Weather services via XML Application available to industry standard Mobile devices

Example of Web Application Military HomeFront Portal
Integrated OGC WMS Image Feed
Mobile Application Requirements Must use the existing Enterprise Infrastructure All functionality must be available to the mobile device –Map rendering and navigation including pan/zoom –Routing –POI searches –External services – weather/image MUST BE INTUATIVE AND EASY TO USE
Development Considerations Limitations of Mobile Devices –Support of JavaScript –Navigation tools –Interactive Screens –No cursor –Limitation of various mobile browsers –Blackberry –Windows CE / Mobile Internet Explorer
Development Approach Mobile Specific Path – WURFL – Exact match / Loose match –Only trust exact match –Screen size Windows Headers –Screen size BlackBerry User Agent Automatic redirect if sure
Development Approach (Cont.) SiteMesh –Page headers and overall layout differences Struts –Model View Controller –Same code for different presentation JSP Includes –Majority of HTML same for mobile/desktop CSS / HTML –HTML tags indicate content type –CSS indicates content style
Installation Location
Mapping of Services
Locating POI’s
Routing
Supported Mobile Devices Blackberry Palm Treo HP iPAQ
Conclusion Advantages of the Enterprise Architecture Single source of data Single source of application code Web application code mostly reusable Server side processing –No need for any application code on the mobile device Ability to integrate web services at the middel tier –OGC WMS Image Services –XML Weather Services Leverage Enterprise Security Model if required CHEAP AND FAST TO BUILD THE MOBILE APPLICATION
