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

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 –

http://militaryinstallations.dod.mil/mobile/

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
