1 Palm Beach County, Florida Planning, Zoning, Building (PZB) Department WLIA 2002 Reserve Address Manager Application -- A Case Study in Application Integration -- Reserve Address Manager Application -- A Case Study in Application Integration --

2  Application Integration o Two Web Applications that talk to each other o Simulation of emerging “Web Services” technology  Use of COTS Components o ArcIMS ASP Template  Use Case/UML Modeling as a Design Method PZB Reserve Address Manager

3  Host Web application (ASP) o Table Updates for Reserved Street Names and Addresses  Geographic Web application (ArcIMS- ASP) o Access via the Host Web application o Performs supporting “Geographic Lookup” for Host PZB Reserve Address Manager: Component Parts

4 Host Web Application  Process o Management of Reserved Street Names and Addresses for Subdivision Pre-Approval  Purpose o Create an Address/Street name reservation and assignment at approximate location of a Parcel not yet recorded o Functional implementation of addressing standards o Audience: PZB Staff and Municipal Staff  To integrate, the Host requires… o Controls for Initial Navigation o Form to hold returned values o Javascript functions

5 Initial PLSS Navigation Range= 43 Town = 47 Section= 31 Browse Mode Update Mode Host Web Application: Required Navigation Controls

6 Unassigned Lookup Information Host Web Application: Required Form for Lookup Values

7 Geographic Web Application  Purpose o Provide “Geographic Lookup” functionality for Host o Perform Spatial Analysis (point-in-polygon) on a set of pre-defined data layers…  Use of COTS components o ArcIMS ASP template o Augmented with additional functionality o Augmented with different User Interface

8  User chooses Mode of Navigation o e.g. Navigate by PLSS Section  User chooses Search Value o e.g. Range-Town-Section =  The Geographic Web Application automatically opens to chosen extent Geographic Web Application: Initial Navigation

9 Map Operations Toolbar Secondary Navigation Update / Cancel Controls “Reference Mode” Values Other Map Operations Geographic Web Application: Initial Navigation

10  Lookup Process o Navigate to approximate location (mapping landmarks) o Click on the “Address Point” tool o Click on the map at an approximate centroid of unrecorded parcel o System performs point-in-polygon on a set of data layers… PLSS Section, Commissioner Districts, Municipality, FEMA Flood Zone o Resulting Values displayed on form Geographic Web Application: Geographic Lookup

11 Map Labels… Municipal NameMunicipal Name Commissioner DistrictCommissioner District PLSS SectionPLSS Section Current Parcels Digitized Point Unrecorded Parcel Recorded Lookup Values Update / Cancel Buttons Geographic Web Application: Geographic Lookup

12  Update of Host o Click on Update button o Retrieve lookup values and X, Y coordinates o Populate a form in the Host with these values

13 Updated Information On Hosting Web Form Geographic Web Application: Geographic Lookup

17 Development Methods: Use Case Model

18 Development Methods: UML Model

19 An Architectural Pattern for an ArcIMS Server- side Application Development Methods: Software Architecture

20 Key Concepts  Spatially enabled business applications o COTS components o Embedded and transparent spatial analysis  Application Integration o Use of “Web Service” concept o Internal Flexibility -- architecture of application o External Flexibility -- integrate inter-department workflows  Server-side Solutions o Scalability, use of database services

21 Key Lessons  Thoroughly evaluate COTS components o ASP Template performed poorly, rewritten  Apply UML modeling strategically o Critical use cases, General architecture  Some difficulty implementing pseudo-Web Services o Some configurations need Authentication workarounds o SOAP solutions are here now  Efficient testing is performed on-site o Difficulty in replicating target networks in off-site test environments
