4 Creating Workflow Logic Two Approaches; A workflow language: Business Process Execution Language (BPEL) An XML-based language for defining process logic Originally created by Microsoft and IBM Now owned by OASIS Generalized activities: Windows Workflow Foundation (WF) Each activity is defined as a class Can also support BPEL with appropriate activities 4

5 Workflow Integrated into Middleware IBM WebSphere now incorporates BPEL-based process capabilities, although IBM MQ Workflow still has a large install base Oracle BPEL Process Manager technology incorporated from Collaxa acquisition replaces Oracle Workflow, which is recommended only for legacy installations SAP Webflow (aka SAP Business Workflow) supports Wf-XML, BPML BEA 5

19 Oracle SOA Suite Consists of.. Integrated Service Environment (ISE) to develop services Oracle BPEL Process Manager to orchestrate services into business processes ESB to connect existing IT systems and business partners as a set of services Oracle Business Rules for dynamic decisions at runtime that can be managed by business users or business analysts OracleAS Integration Business Activity Monitoring to monitor services and disparate events and provide real-time visibility into the state of the enterprise, business processes, people, and systems. Oracle Web Services Manager to secure and manage authentication, authorization, and encryption policies on services that is separate from your service logic UDDI registry to discover and manage the lifecyle of Web services. Oracle Application Server 10g Release 3 (10.1.3) to provide a complete Java 2, Enterprise Edition (J2EE) 1.4-compliant environment for your J2EE applications. 19

20 Integrated Service Environment Oracle JDeveloper (JDeveloper) is the development component of Oracle SOA Suite. It forms a comprehensive ISE for developing, composing, and orchestrating services into business processes. Business processes can be deployed, registered, and consumed from several types of user interfaces, including desktop clients, browsers, and mobile and telnet devices. JDeveloper enables developers to model, create, discover, assemble, orchestrate, test, deploy, and maintain composite applications based on services. Oracle ADF is a model-driven SOA framework that automates and manages businesses and data services and provides a standard data-and-service-binding layer based on JSR 227 that can be used with process flows, page flows, and service invocations. Oracle ADF implements SOA design practices and makes user interfaces as loosely coupled as services themselves. 20

21 Oracle BPEL Process Manager Oracle BPEL Process Manager provides a framework for easily designing, deploying, monitoring, and administering processes based on BPEL standards. Oracle BPEL Process Manager adds value and ease of use to BPEL functionality by providing support for the following in the JDeveloper BPEL Designer: Transformations, workflows, worklists, notifications, and sensors Technology adapters, including file, FTP, database, advanced queuing (AQ), Java Messaging Service (JMS), Oracle Applications for Oracle E- Business Suite, and WebSphere MQ Third-party adapters, including J.D. Edwards OneWorld, PeopleSoft, SAP R/3, Siebel, Tuxedo, CICS, VSAM, IMS/TM, and IMS/DB 21

22 Oracle Business Rules Oracle Business Rules enables dynamic decisions at runtime allowing, among other features, applications to rapidly adapt to regulatory and competitive pressures. this increased agility is possible because business analysts using Oracle Business Rules can create and change business rules that are separated from the application code. By using Oracle Business Rules, business analysts can change business rules without stopping business processes. Also, externalizing business rules allows business analysts to manage business rules directly, without involving programmers. 22

23 OracleAS Integration Business Activity Monitoring OracleAS Integration Business Activity Monitoring (BAM) gives business executives the ability to monitor their enterprise business services in real-time and to correlate their KPIs (key performance indicators) to the actual business process. Oracle BAM provides the ability to aggregate service metrics and deliver actionable information on critical business service parameters to user. Oracle BAM delivers information to users through visual dashboards and alerts, improving effectiveness of operations and taking informed decisions. Oracle BAM is a complete solution for building real-time operational dashboards, monitoring and alerting applications. 23

24 Oracle Web Services Manager Oracle Web Services Manager is a security administrator's environment designed to secure access to Web services and monitor activities performed on protected Web services. Oracle Web Services Manager includes two main parts: policy decision point (PDP) : The PDP includes security and management components accessed through a Web-based management console providing Oracle Enterprise Manager's look and feel. policy enforcement points (PEPs): PEPs are interceptors that can be either agents or gateways. Agents run in the same container as the Web services they protect whereas gateways are independent processes analogous to proxy servers. Agents and gateways can be used in combination to ensure end-to-end Web services security. 24

25 Oracle Enterprise Service Bus (ESB) An enterprise service bus moves data among multiple endpoints, both within and outside of an enterprise. It uses open standards to connect, transform, and route business documents (as Extensible Markup Language (XML messages), among disparate applications. It enables monitoring and management of business data, with minimal impact on existing applications. An enterprise service bus is the underlying infrastructure for delivering a service-oriented architecture (SOA) and event-driven architecture (EDA). ESB is the foundation for services using SOA and EDA. At its core, it is a loosely coupled application framework that provides your business with increased flexibility, reusability, and overall responsiveness in a distributed, heterogeneous, message-oriented environment using industry standards. 25

26 OracleAS UDDI Registry OracleAS UDDI Registry provides a key component of any SOA with a configurable, scalable, secure repository of Web services that can be managed, discovered and governed by Oracle Fusion Middleware. The OracleAS UDDI Registry meets the core service management needs of any enterprise: Enables service providers to publish and advertise their offerings Allows service consumers to find, access, and invoke services that meet defined criteria Provides critical features for SOA governance Integration is provided with other products in the Oracle Fusion Middleware family, including Oracle BPEL Control, Oracle Web Services Manager, and JDeveloper, enabling users to query the Registry for published services. 26

27 Oracle Application Server Oracle Application Server is a standards-based application server that provides a comprehensive and fully integrated platform for running Web sites, J2EE applications, and Web services. 27

50 .NET Framework The.NET framework has two components: The common language runtime Agent that manages code at execution time, providing core services such as memory management, thread management, remoting, etc.net framework class library Object-oriented collection of reusable types that can be used to develop applications ranging from traditional commandline or graphical user interface (GUI) applications to applications based on the latest innovations provided by ASP.NET, such as Web Forms and XML Web services. 50

51 What is ASP.NET? Hosting environment that enables developers to use the.net Framework to target Web-based applications. Architecture for developing Web sites and Internet-distributed objects using managed code. XML Web services use ASP.NET as the publishing mechanism for applications. 51

52 J2EE 52

53 What is J2EE? Java 2 Platform, Enterprise Edition Component-based approach to the design, development, assembly, and deployment of enterprise applications Not tied to the products or APIs of any one vendor Freedom to choose products/components that best meet needs J2EE Offers: Multitiered distributed application model Ability to reuse components XML-based data interchange Unified security model Flexible transaction control 53

54 Distributed Multitiered Applications Application logic is divided into components according to function and the various application components that make up a J2EE application are installed on different machines depending on the tier in the multitiered J2EE environment to which the application component belongs. The J2EE specification defines the following components: Application clients and applets: run on the client. Java Servlet and JavaServer Pages (JSP) technology Web components that run on the server Enterprise JavaBeans (EJB) components (enterprise beans) business components that run on the server 54
