An open agreement n 21/01/2001 A special type that defines a single organization. The missing trading partner information is provided when the document is submitted to Biz. Talk. Internet DB Seminar 7
Document Specifications n n n Document specifications define the structure of a business document in a way that is independent of the underlying data format. Biz. Talk represents document specifications internally with XDR (Will be replaced by XML Schema Definition Language - XSDL). A business document’s physical format may be XML, UN/EDIFACT EDI, X 12 EDI, positionally delimited flat files , or commaseparated values. 21/01/2001 Internet DB Seminar 8
Document Specifications (Cont. ) n n Document specifications are required to define the translation from the original document format to the Biz. Talk Server 2000 intermediate XML format. Business analysts must review schema initiatives in their industries, perform gap analysis between published specifications and internal business requirements, and negotiate details with trading partners. 21/01/2001 Internet DB Seminar 9

Document transformation n The Biz. Talk Mapper transforms a document from the internal XML representation of an inbound document to the internal XML representation of an outbound document. This mapping allows Biz. Talk Server 2000 to alter the schema (transformation) and data format (translation) of business documents. The Biz. Talk Mapper uses standard XSLT technology to internally represent mapping rules. 21/01/2001 Internet DB Seminar 12
Document transformation (Cont. ) n n n Microsoft XSLT implementation provides COM and scripting language integration. Biz. Talk Mapper take advantage of this integration to provide built-in reusable components called functoids (String, Mathematical, Logical, Date, Conversion etc). Functoids allows the developer to define custom script logic that will be applied to source data values during the execution of a map. 21/01/2001 Internet DB Seminar 13

Pipelines n n n Pipelines tie together the built-in or custom processing steps during a data interchange. Certificate identification and processing rules are defined within a pipeline. Custom components may be inserted into a pipeline. 21/01/2001 Internet DB Seminar 16
Transport Services n n Biz. Talk Server 2000 supports the following transport services: HTTP, HTTPS, SMTP, MSMQ, FTP, file, and fax. Documents may also be sent with a custom COM. 21/01/2001 Internet DB Seminar 17
Receive functions n n Receive Functions allow applications to submit business documents to Biz. Talk. FTP, file, and message queuing are supported receive functions. 21/01/2001 Internet DB Seminar 18
Receive functions (Cont. ) n n n The FTP receive function polls a given location and uses FTP to send files to Biz. Talk. The file receive function is invoked by a file system event when activity occurs in the defined directory. The source file is copied and submitted to Biz. Talk. The message queuing receive function provides event-based integration with MSMQ to read messages from a queue and submit the message body to Biz. Talk. 21/01/2001 Internet DB Seminar 19
Architecture and Tools n n n The Biz. Talk Server uses Windows 2000 Server and Microsoft SQL Server to implement document interchange engine. A standard deployment may include one or more Biz. Talk servers configured as a group. Server groups share document specifications and maps through the Windows 2000 Web Distributed Authoring and Versioning (Web. DAV) service. 21/01/2001 Internet DB Seminar 20
Architecture and Tools (Cont. ) n n The servers share working interchange data by accessing a set of shared SQL Server queues. Four SQL Server queues are used during the processing of a document: scheduled queue, work queue, retry queue, and suspended queue. 21/01/2001 Internet DB Seminar 21
Biz. Talk Server 2000 Deployment 21/01/2001 Internet DB Seminar 22
Document Processing n n Business data is submitted to Biz. Talk as text. The server selects the appropriate parser based on the agreement. The parser looks up the document specification defined in the agreement, and uses it to create intermediate XML representations of the submitted business data. If the parsing step fails, the document will be placed in the suspended queue. 21/01/2001 Internet DB Seminar 23
Document Processing (Cont. ) n n The server validate the structure and grammar of the document. The server loads the map defined in the agreement’s pipeline configuration and applies the transformation to the document. The document is serialized. The document is transported. 21/01/2001 Internet DB Seminar 24
Security n n SSL support is provided through the built-in HTTPS transport service. Documents may also be encoded using builtin S/MIME encoding components. The Public Key Cryptography System (PKCS) for encrypting and decrypting document is supported. Digital signatures may be applied to outbound messages and verified on inbound messages. 21/01/2001 Internet DB Seminar 25
Management and Analysis Tools n Biz. Talk Management Desk n n allows the recreation and configuration of trading partner agreements and all associated properties (organizations, distribution lists, document specifications, envelopes, transport protocols, security settings, and pipelines). Microsoft Management Console (MMC) n 21/01/2001 Using this console, groups, queue activity, receive functions and individual servers may be managed remotely or locally. Internet DB Seminar 26

Biz. Talk Orchestration (BTO) n n Biz. Talk Orchestration is a new technology for creating and orchestrating business processes that span time, organizations, applications and people. BTO is based on a new application of XML called XLANG, which is a language created to define the semantics of business processes and to bind process activities to software implementations. 21/01/2001 Internet DB Seminar 29
Biz. Talk Orchestration Goals n Separation of Definition from Implementation. n n n The process definition must not be tied to or driven by implementation details and vice versa. Dynamic Processes. “Any to Any” Integration. n 21/01/2001 The process must be able to communicate and interact with any of the constituent parts of the implementation of the process. Internet DB Seminar 30
BTO Overview n n Biz. Talk Orchestration makes a distinct separation between the process definition and the underlying implementation. It allows the process to be modified and maintained without breaking the underlying software implementations, and vice versa. 21/01/2001 Internet DB Seminar 31
(. BTO Overview (Cont n n It allows flexibility of hardware and software choice. The underlying implementations can be upgraded or changed entirely without throwing away the work done to define the process. It makes it easy to add new elements and new participants to the process. 21/01/2001 Internet DB Seminar 32

Case study - Marks & Spencer n Business Challenge n n Marks & Spencer needed to ensure that point-of-sale (POS) data from its stores was transmitted to its data center as quickly as possible. Solution n 21/01/2001 Microsoft Windows® 2000 Server in each store, connected through a LAN to POS terminals running a Windows client. Internet DB Seminar 36
Case study (Cont. ) n Solution (Cont. ) n n 21/01/2001 Transactions flow from each POS terminal to the server, where every 60 seconds they are aggregated, converted to an XML message, and sent to the corporate data center using the Microsoft Message Queuing Services (MSMQ) Biz. Talk Server 2000 receives the XML messages, load balances them across all of the Biz. Talk processing servers, examines their contents, and intelligently routes the data to the appropriate application in the correct format. Internet DB Seminar 37
