B2B Application Integration COSC643 Sungchul Hong

Goal Understand current B2B related applications Understand the relationships among B2B application Integration of B2B applications.

E-Business Web-enabled selling Middle-ware Internet-enabled supply chain integration –EDI (Electronic Data Interchange) Flow of information and material –Information Systems

Introduction E-business characteristics –Instantaneous –All participating systems are able to communicate in any direction. –Systems are bound at both the data and process levels. –All relevant information existing in any participating system is accessible by any other participating system.

Real Time Business Purchase of a new car –Orders a car at a dealership –Manufacturer –Parts, supplier Raw materials –Manufacturing –Dealer

EDI (Electronic Data Interchange) Many owners of supply chains already use it. Sharing information –Order or payment data Partially automated –It is not good enough

Different Systems and Different Standards What is the price? How can we represent it? If you have different systems, how can we make these systems communicate each other? Which method is the best?

B2B Application Integration After years of creating islands of automation within each company, users and business managers are demanding that seamless bridges now be built to join these islands together. Financial prudence Opportunity for profit

B2B Application Integration It is the mechanisms and approaches to allow partner organizations, such as suppliers and consumers, to share information in support of common business events. If company A has a sales order entry system that provides a system for recording sales, then company B, a part supplier, must have a parts system that is instantly integrated with company A’s sales system.

Traditional Approach Traditional middleware was built to integrate applications within an enterprise and does not take into account the special needs of B2B integration. Point-to-Point solution

Middleware Middleware is a mechanism to move information and shared business logic between applications. During business transactions, the middleware hides the complexity of the underlying operating system and network and allows information exchange on be half of the application programs.

Categories of Middleware TP Monitors Message Brokers Application Server Distributed Objects

Business Rues Integration Binding of application logic between tow or more e-Business partners. The composite applications that exist are accessible to all interested parties. The exchange of both information and business rules is fully automated CORBA

Information Integration Lower level than business rules integration Message brokers, data replication engines, and data migration engines. (XML) Provide a platform for exchanging relevant business data in order to support e-Business initiatives. (order and invoice data) Inexpensive

Process Integration Provides a set of processes that function above both business rules and information integration. Provide abstract business layer that exists over the physical one. (logical flow of information)

Collaboration Providing a geographically dispersed workgroup with the opportunity to share messages and other information in real time to support a business need. Customer relationship management, online customer service, virtual product development. Provide interface to human and systems.

Types of Middleware   Remote procedure calls (RPC) type  synchronous   Message oriented message (MOM) type  asynchronous   Message Broker type.  Asynchronous and many-to-many transactions

 DistributedComputing Environment (DCE) from the Open Group. (RPC)  MSMQ from Microsoft (MOM)  MQSeries from IBM (MOM)  Tuxedo from BEA systems (TP Monitors)  MTS from Microsoft (TP Monitors)  CICS from IBM (TP Monitors)  Enterprise JavaBeans from SUN (application server)  SAP R/3 (application server) –COM+ (with AppCenter) from Microsoft (application server & distributed objects)

Middleware Vendors BEA SAGA Software IBM NEON Tibco SUN

Point-to-Point Middleware Message queuing Remote procedure calls Traditional middleware requires significant alterations to both the source and target systems. Integration of a custom accounting system running on Windows 2000 and a custom inventory control system running on a main frame within another company. According to the Aberdeen Group, dual- application linking cost is as high as $10 million.

New Middleware Features Support for inter-and intra-process integration Support for B2B standards including RosettaNet, ebXML, and EDI Support for Internet-enabled information exchange Support for advanced security models

Types of B2B application Integration Data-oriented Application interface-oriented Method-oriented Portal-oriented Process integration-oriented

Data Oriented It is the process or technology of extracting information from one database and updating it in another database within another organization. Large number of databases It may also include the transformations and application of business logic to the data. Cost is the advantage.

Application Interface-Oriented Developers are able to bundle any number of application and allowing them to share business logic and information. Need specific features and functions of the application interface. Packaged application SAP, PeopleSoft, Baan (Vendors)

Method-Oriented Sharing business logic that exists within the enterprise. Distributed objects Application server Transaction Process (TP) monitors frameworks

Portal-Oriented Application architects can integrate applications by presenting information from several local or partner applications within the same user interface.

Process Integration-Oriented It provides those who are supporting B2B application integration with a business- oriented and and process automation-like view of how business information flows between trading partners. Collaboration-level B2B application integration
