  1. introduction to soarchitect

  2. agenda • SOA background and overview • transaction recorder • summary

  3. developer suite • integrated, on-the-fly environment • reuse existing applications • rapidly extend and integrate • modular architecture • add modules as required • broad functionality • rapid ROI from UI frameworks • supports non-invasive and invasive modernization • deliver new solutions with composite applications • service-enable existing assets for web services and SOA

  4. looksoftware dynamic environment

  5. web services and SOA • SOA is an architecture • goal is to increase reuse • the concept is not new • web services standards • have industry-wide support • SOAP, UDDI, WSDL • continue to evolve • this presentation focuses on practical web service enablement of iSeries applications

  6. web services and SOA • the vision • “by 2006, 60% of organizations will be using SOA” • “composite applications are entering maturity on the hype cycle” • “Software As A Service will be THE business model of choice by 2008” Source: Gartner • the reality for the iSeries market • it’s early days for web services, let alone SOA • selective service enablement provides reuse benefits • without redevelopment or invasive restructuring

  7. web services and SOA • any language (RPG, COBOL) can support SOA • service enablement of existing applications • changing the application is typically not required • may span part of a program or multiple programs • access available at all layers • presentation (5250, 3270) • application (RPG, COBOL, Java, C#...) • data (DDM for DB2, ADO for SQL Server Oracle…) • important questions • be practical, where is the ROI? • what is the “right” level of granularity?

  8. web services and SOA • service enablement benefits • wrap once, access from anywhere • improved interoperability • component level access to existing applications • increased reuse, flexibility, productivity • eg multi-channel delivery • non-invasive • reduced risk, timeframes, costs • rapid ROI

  9. web services and SOA • consumption versus provision • consumption (calling) a web service • eg third party Address Validation service • provision (creating, exposing) a web service • eg external entity accesses your application • the focus of this session

  10. questions for SOA products • How does soarchitect support SOA? • What are the benefits of soarchitect to your business?

  11. questions for SOA products • our solution: • no need to change your applications • Transaction Recorder to simplify Web Service definition • no new languages need to be learnt • requires lookserver and your current infrastructure • does not impact your use of RPG/COBOL • can work with your existing applications

  12. soarchitect primary capabilities • create a web service from an existing iSeries application • transform a monolithic iSeries program to a number of services • service-enable existing applications to provide the benefits of SOA

  13. soarchitect • Transaction Recorder for packaging existing 5250 applications • script access for • DDM database access • ADO database access • RPC for execution of iSeries programs and commands • execution of external Web Services • execution of COM/ActiveX components

  14. case study - VicRoads • background • statutory authority for vehicle registration • responsible for 4 million vehicles • stable, robust iSeries and zSeries applications • call center issues • 3.8 minutes per call • 400,000 calls per annum • operators switch between 3 different systems • potential for data entry errors • re-keying of data • potential legal liabilities

  15. VicRoads existing system • 3 separate core applications • green screen user interface • re-keying, Alt/Tab process

  16. VicRoads iSeries screen flow sign on mainmenu enquiry menu inputvehicleidentifier confirm prompt outputencumbrance type

  17. create a reusable service module sign on mainmenu enquiry menu inputvehicleidentifier confirm prompt outputencumbrance type transaction

  18. transaction recorder

  19. transaction recorder • records 5250/3270 screen flows • creates a transaction • reusable component • enables work offline • exposed as a web service

  20. transaction recorder • records 5250/3270 screen flows • creates a transaction • reusable component • - enables work offline • - exposed as a web service • transaction consists of • - a collection of steps

  21. transaction recorder • records 5250/3270 screen flows • creates a transaction • reusable component • - enables work offline • - exposed as a web service • transaction consists of • a collection of steps • navigation

  22. transaction recorder • records 5250/3270 screen flows • creates a transaction • reusable component • - enables work offline • - exposed as a web service • transaction consists of • a collection of steps • navigation • - input/output parameters • - literals

  23. transaction recorder • records 5250/3270 screen flows • creates a transaction • reusable component • - enables work offline • - exposed as a web service • transaction consists of • - a collection of steps • - navigation • - input/output parameters • literals • events • - trigger additional processing

  24. VicRoads existing system • 3 core applications • green screen user interface • rekeying, Alt/Tab process

  25. VicRoads Step 1 smart client

  26. VicRoads results • reduced average call duration by 40-50% • automated workflow • 25 host green screen transactions across 3 applications • modules can be reused as web services • eliminated re-keying of data and switching between applications reducing errors • no changes to host applications • ROI in 4 months

  27. VicRoads existing system • 3 core applications • green screen user interface • rekeying, Alt/Tab process

  28. VicRoads Step 1 smart client • defined reusable service modules • smart/rich client provides unified view • automate business process • no changes to host applications

  29. VicRoads Step 2 IVR • reuse same service modules • integrate with Interactive Voice Response (IVR) • bypass call center • further cost savings, improve customer service

  30. VicRoads Step 3 XML documents • reuse same service modules • trading partner collaboration • batches of vehicles require same checks • further reduce costs, improve partner service

  31. VicRoads summary • reuse same service modules • deliver “new” solutions through multiple channels • no changes to existing applications • practical path to SOA

  32. VicRoads summary • build SOA, create more services modules • improved productivity and flexibility • capability to deliver composite applications • refining, streamlining business processes

  33. VicRoads summary • services layer provides insulation against change • change the backend, minimal impact on business • practical path to SOA

  34. summary • soarchitect can SOA enable your existing applications • you can interface at the presentation, program or database levels • you do not need to change the way you develop your applications • creates componentized applications which are better for modernization and integration
