Why Web Services? Business logic that can be invoked through standard internet protocols Self-contained Self-describing

Service Oriented Architecture Broker Publish Find Bind Provider Requestor

Types of Web Services Business Information -Stock quotes -Currency conversion -Geographical data Business Integration -Reservation system -Credit check -Product catalogue

Web Services / SOA -Service and message- centric -Loosely coupled -Cross-domain IT infrastructure -Application-centric -Tightly coupled -Isolated silos -Dependencies on: Software infrastructure Hardware infrastructure HR Web App SAP Sales Web App Peoplesoft Order Processing Domino Exchange Database Process an Order Look-up Customer information Apply for a Mortgage New Dynamic Business Paradigm – SOA

Needed: True root cause analysis -web service fails -why? -Root cause… -Application logic? -ERP, mail, others? -Servers? -Database? -Network? -Hardware? -All of the above?

Web Services Benefits Provider Benefits - Reduce operating costs -Create a new revenue channel -New life to legacy applications -No distribution costs or time lag -No variation in user version and configuration

Web Services Benefits Benefits to Requestors -Programmatic access to wealth of information -Simply use Web services: no install, configuration, maintenance -Choice of providers Benefits to Both -Built on Open standards -JIT integration: service requestors have to agree only on interface and not on implementation

YGENWSPXY will create a 2E function definition in the model. The function type is new: Web Service Proxy WSPXY). WSPXY is a similar to an EXCUSRPGM, i.e. It does NOT have an Action Diagram. YGENWSPXY will automatically generate the source for the WSPXY function definition. NOTE: At release r8.1, YGENWSPXY will generate RPG ILE source. AllFusion 2E: Generate WS Proxy
