  1. Pete Boysen ThinkSpace ThinkSpace Design

  2. ThinkSpace Design Outline • Demo • Programming Environment • System Architecture • Example Code

  3. ThinkSpace Design Demo • ThinkSpace in hosted mode

  4. ThinkSpace Design Programming Environment • Enterprise Development • Thousands of users • Clustered computers • Must support Windows,Mac and Linux • Multiple diverse applications • Limited Staff (me) • Limited Funds • Bottom Line: can one person support the needs of the many?

  5. ThinkSpace Design Oh, CRUD • Many widgets will issue CRUD operations automatically • You can directly call DataSources to fetch(read), add(create), remove(delete) or update(update) • You can add datasource parameters if needed

  6. ThinkSpace Design System Architecture Browser XQuery think?a=1&b=2 SmartGWT ThinkSpace XML Tomcat Model – XML files and DB data View – SmartGWT Controller - XQuery AFS DB

  7. ThinkSpace Design Available Resources • HTML Editor • Librarian Widget (file manager) • Note Taker • Video and chat conferencing tool

  8. ThinkSpace Design <profile help="false" photo="" forward="" provider=""theme="SilverWave"> <apps> <app> <id>libraryapp</id> <name>Library of files</name> <description>Manage your files</description> <icon>apps/Notes.png</icon> <category>Utility</category> </app> </apps></profile> Example - Profile • Theme • Email Forward • Cell Provider • Photo • Selected Apps

  9. ThinkSpace Design Profile - Browser • Create DataSource dataSource = new ProjectDataSource ("ThinkSpace", "ThinkSpace", "profile.xq"); • FetchData dataSource.fetchData(); • Parse XML photo = XMLTools.selectString(data,"/response/data/profile/@photo"); • Populate Interface

  10. ThinkSpace Design Testing • TestServiceImpl is provided to test data transfer in hosted mode • _operationType is sent to servlet along with name of xquery file • Servlet looks for file path (model=ThinkSpace, xq=profile.xq)data/ThinkSpace/profile.xq.xml

  11. ThinkSpace Design profile.xq.xml • <xq> <fetch> <response> <status>0</status> <data> <profile help="false" photo="" forward="" provider="" theme="SilverWave"> ..... </profile> • </data> </response> </fetch> <add>...</add> <update>....</update> <remove>...</remove></xq>

  12. ThinkSpace Design Suggestions • What object does a widget need? • Separate small XML files is preferable to one large file • Data can be paged (example: gradebook of 1000 students) • Browser limits async calls to two at once
