Professional BizTalk Server 2006
Pipelines:
- Components within the BizTalk system that are able to process messages either when they are received or just before they are sent out
- Pipelines divide processing into several categories, known as processing stages
- They also specify the sequence in which each stage of the work is performed
Processing stages:
- Define logical work groups
- Determine which components can belong to a stage
- Specify how the pipeline components in the stage are run
Stages in a pipeline include:
- Encrypting and decrypting
- Encoding and decoding
- Assembling and disassembling
Receive Pipeline:
- Receive pipeline takes the initial message, performs transformations, and disassembles the raw data into zero, one, or multiple messages
- These are XML messages that are then sent to be processed through the BizTalk server
Receive Pipeline Stages, each receive pipeline consists of the following four stages:
- Decode: used to decode MIME encoded messages
- Disassemble: used to normalize messages from native incoming format to BizTalk Server's internal XML format
- Validate: used to verify an incoming document against a specified schema
- Resolve party: used to verify that the incoming message was sent from a trusted source
Send Pipeline:
- Responsible for processing documents before they are sent to their destination
- Each send pipeline accepts one message and produces one message to be sent
Send Pipelines consist of three empty stages:
- Pre-assemble: used to conduct processing on the message needed before it is assembled
- Assemble: used to assemble the BizTalk XML document into a XML, flat-file, or a BizTalk Framework (BTF) format
- Encode: used to encode the document to MIME/SMIME and to digitally sign messages
Using a Default Pipeline
Pass-through receive:
- Contains no components
- No decoding, validation, or disassembling required
- Used when both send and receive destination are known and is commonly used in conjunction with the pass-through send pipeline
Pass-through send:
- Contains no components
- No encoding or assembling required
- Used for basic message routing
- Commonly used in conjunction with the pass-through receive pipeline
XML receive:
- Contains the XML disassembler component
- Party resolution component for security
- No decoding or validation stage
XML send:
- Contains the XML assembler component (Preassembling, Serializing, Encoding)
