Application Integrationo Two Web Applications that talk to each othero Simulation of emerging “Web Services”

technology Use of COTS Components

o ArcIMS ASP Template Use Case/UML Modeling as a Design

Method

Host Web application (ASP)o Table Updates for Reserved Street Names

and Addresses Geographic Web application

(ArcIMS-ASP)o Access via the Host Web applicationo Performs supporting “Geographic Lookup”

for Host

Host Web ApplicationHost Web Application

Processo Management of Reserved Street Names and Addresses for

Subdivision Pre-Approval

Purposeo Create an Address/Street name reservation and assignment

• at approximate location of a Parcel not yet recordedo Functional implementation of addressing standardso Audience: PZB Staff and Municipal Staff

To integrate, the Host requires…o Controls for Initial Navigationo Form to hold returned valueso Javascript functions

Geographic Web ApplicationGeographic Web Application

Purposeo Provide “Geographic Lookup” functionality

for Hosto Perform Spatial Analysis (point-in-polygon)

on a set of pre-defined data layers… Use of COTS components

o ArcIMS ASP templateo Augmented with additional functionalityo Augmented with different User Interface

88

User chooses Mode of Navigationo e.g. Navigate by PLSS Section

User chooses Search Valueo e.g. Range-Town-Section = 43-47-30

The Geographic Web Application automatically opens to chosen extent

Key ConceptsKey Concepts

Spatially enabled business applicationso COTS componentso Embedded and transparent spatial analysis

Application Integrationo Use of “Web Service” concepto Internal Flexibility -- architecture of applicationo External Flexibility -- integrate inter-

department workflows Server-side Solutions

o Scalability, use of database services

2121

Key LessonsKey Lessons

Thoroughly evaluate COTS componentso ASP Template performed poorly, rewritten

Apply UML modeling strategicallyo 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
