2. ENTERPRISE ARCHITECTURE CENTER OF EXCELLENCE 2 Introduction  About this presentation  Problem  Solution  Benefits  Domain Example  Service Oriented Architecture (SOA)  An architecture approach that facilitates integration and promotes information sharing  Business capability delivered through a collection of services that are shared across the enterprise  Requires a common/shared understanding of the organization’s data

3. ENTERPRISE ARCHITECTURE CENTER OF EXCELLENCE 3 Business Problem  Difficulty arising from multiple data exchange standards  Need for interoperability of multiple technology standards  Subscribers individually negotiating with single entity creating multiple streams of same source data  Multiple versions of the truth  Lack of end-to-end traceability of data exchanges  Lack of prompt dissemination of data

8. ENTERPRISE ARCHITECTURE CENTER OF EXCELLENCE 8 The Solution Presentation Layer All information is displayed through consistent interfaces, using a common look and feel across the agency Shared Services Common functionality is packaged into discrete services which can be reused across the enterprise Enterprise Application IntegrationExtract, Transform & LoadBusiness Process ManagementEnterprise Content Integration COTS Applications Custom Applications HTML DB Applications Business Services Reporting Services Content Services Content Services Business Activity Monitoring Shared Portal Executive Dashboards Content Services Data Services Content Services Other Services Presentation Services ContentDatabase Operational Data Store Data Warehouse & Data Marts Information Sharing Environment is a set of tools, processes, and technologies that will enable information sharing and reuse of business functions across an organization

9. ENTERPRISE ARCHITECTURE CENTER OF EXCELLENCE 9 The Information Sharing Environment (ISE) design uses an Enterprise Services Bus to implement the business functionality following a SOA approach. Service-Oriented Architecture Approach  Business Services – This layer is used to expose the functionality using various technical protocols. Both JMS and SOAP protocols may be used together or individually to extend functionality specified by a core services layer.  WSDL to expose API for SOAP calls  XSD definition for JMS implementation.  Core Services – This layer contains the main processes which implement workflow integration. These are defined as stand alone. Core services utilize both common services and reusable services.  Common Services - Processes which implement common functionality  Reusable Services - Sub-Processes

10. ENTERPRISE ARCHITECTURE CENTER OF EXCELLENCE 10 Business Benefits Single Version of Truth: One version of data is shared across all systems Open: Enables communication with legacy systems and other agencies Accurate: Ability to create more timely and accurate operational reports Cost-Efficient: Lowered implementation, support and maintenance costs Secure: Enhanced security between all systems; secure each interface once Modular: Legacy systems are retired without affecting downstream systems Reliable: Guaranteed message delivery and monitoring Architecturally Efficient: Eliminate stovepipes and redundant interfaces Data Warehousing: Lays foundation for Business Intelligence and ODS

11. ENTERPRISE ARCHITECTURE CENTER OF EXCELLENCE 11 Domain Example Using the Service Oriented Architecture (SOA) Approach :  Build a component, not a complete application  Ease of adding or replacing new interfaces  Support for industry standard protocols  Schema support for W3C XML  Uses standards in construction of messages being sent to downstream systems: NIEM (GJXDM & TWPDES) compliant  Enhancement requirements for federated query and role-based access capabilities  Allows necessary changes quickly
