Large Enterprise Medium Enterprise i Small Enterprise Small Enterprise Figure 9.9. — Exchange of data in a typical B2B scenario As depicted in the figure, in a typical B2B scenario, a company can exchange data with other companies through multiple channels 9.4.6. Directory services As seen in the multi-hub architecture figure, a real world implementation is completely distributed in nature with multiple instances of integration brokers connecting several applications and middleware resources. Directory service of an integration broker is like yellow pages that maintain an index of all source and target applications along with their location, communication protocol and use. It provides a single point of entry, also known as a gateway, along with search facilities for all the applications and resources connected by the broker. 9.4.7. Trading partner management and personalization Integration brokers should provide a metadata repository, which can store the definition, preferences and technical specifications (such as
270 B2B Integration — A Practical Guide to Collaborative E-commerce communication protocol, XML/EDI standard, delivery channel and security requirements) unique to each trading partner relationship. Storing all this information would greatly increase the speed of conducting business and would enable companies to offer personalized services to each customer, supplier and distributor. Usually integration brokers provide a graphical administration tool, which lets the users define and manage relationships (i.e., adding or removing a new partner, granting and revoking access to privileges, etc.) with each trading partner. 9.4.8. Security Integration brokers should provide a complete security solution, using encryption, PKI, digital authentication, digital certificates SSL and S/ MIME encryption. They should also maintain a transaction audit trail, through which data privacy, data integrity and transaction non-repudiation (i.e., non-repudiation of origin and non-repudiation of receipt) can be ensured. 9.4.9. Scalability Integration brokers should provide a scalable platform that can support a company's business today and for years to come. They should be optimized for multi-processor systems and enable load balancing and failover solutions through a clustered architecture. 9.4.10. Transactional integrity Integration brokers must provide transactional integrity (event-based processing, exception handling and built-in recovery) at every step, activity and node for each transaction and business process that flows through them. Typically, a business transaction is composed of several logical units of work and each unit of work must be completed successfully in order for the transaction to be committed. If even one unit of work fails, the whole transaction fails and all completed units of work have to be rolled back (reversed).
