introduction
Introduction
  • BizTalk belongs to the Microsoft Server family
  • Connects disparate systems together
  • Communication among systems are established through messages
  • All messages inside Biztalk are XML data
  • Since XML can be interpreted in any system, BizTalk helps in connectivity
need for communication
Need for communication
  • An organisation may follow a software with different configuration for a process and another software with entirely different configuration to take care of another process
  • Both processes may depend on each other’s data
  • For example a company’s attendance system need to be connected with payroll system
  • Or a purchase order need to be communicated to invoice generating system

overview of basic configuration
Overview of Basic Configuration
  • Basic configuration does not allow remote SQL server. To use remote SQL server use custom configuration
  • The following need to be configured:
    • Enterprise SSO (Single Sign On)
      • This is used for managing credentials of users who can log on the server.
      • Enterprise SSO Secret BackUp
        • This keeps the password that can be used for taking a back up of credentials in case of any system crash.
      • After configuring this component a database SSODB is created in MS SQL server
basic configuration contd
Basic Configuration Contd..
  • Group
    • Collection of settings that govern the way BizTalk server behaves and the data store it uses
    • After this step the following databases – BizTalkMgmtDb, BizTalkMsgBoxDb, BizTalkDTADb are created
  • BizTalk Runtime
    • This is to manage the routing capabilities
basic configuration contd9
Basic Configuration Contd..
  • MSMQ – Microsoft Message Queue. This is to manage messages that are transferred to and from the server
  • Business Rules Engine – This configuration takes care of business rules necessary for the server.
    • The configurations are stored in BizTalkRuleEngineDb.
    • Service used is Rule Engine update service.
    • Initiates action based on evaluation
basic configuration contd10
Basic Configuration Contd..
  • HWS – Human Workflow Services
    • Two components
      • HWS Runtime
      • HWS Webservice – encapsulates the functionality of client applications like sharepoint to provide workflow capabilities to information workers
    • DB – HwsDb
    • Service – HWS Runtime Account and HWS Webservice Account
    • This dynamically composes workflow
basic configuration contd11
Basic Configuration Contd..
  • BAM – Business Activity Monitor
    • BAM Tools – Provides business users a set of monitoring tools
      • BAM Alerts – Notification services are provided based on subscription
        • Uses DB like BAMAlertsNSMainApplication
      • BAMPrimaryImport, BAMStarSchema, BAMArchieve, BAMAnalysis are the other databases used
    • BAM Portal – Service used is BizTalk EDI/AS2 Runtime. Messages are sent and received using EDI/AS2 Protocol
biztalk editor overview
BizTalk Editor - Overview
  • Editor is used for generating Schema.
  • BizTalk generates XDS (XML Schema Definition) as the application communicates through XML
  • Editor comes as a part of Visual Studio IDE.
  • In VS IDE, create a biztalk project and add a schema file to create a schema.
creating xsd
Creating XSD
  • Open Visual Studio 2005 (if you are using BizTalk 2006 and higher version)
  • Click on File -> New Project
  • Select BizTalk Projects and click on Empty BizTalk Application
  • Give a name and click OK
  • In the solution explorer, right click on the project and select Add -> New Item
  • Select Schema Files on the left pane and select Flat File Schema Wizard.
  • Refer to the screen shots for further processes.
flat file schema wizard
Flat File Schema Wizard
  • Refer to notes page for explanation
generating xml from the xsd
Generating XML from the XSD
  • Right click on the Project and select Validate Schema
  • Once the validation is over, click on Generate Instance Message.
  • An empty XML file with sample data entry in accordance to the schema will be generated.
  • This XML file can be modified and used with any application that supports XML.
biztalk mapper overview
BizTalk Mapper - Overview
  • Mapper is a tool that is used for mapping data
  • The source data is mapped with the destination data
  • Since BizTalk involves with connecting disparate systems, the source data need to be transformed to another format acceptable by the destination.
  • Hence Mapper plays a vital role.
  • Mapper too comes integrated with VS IDE.
creating maps
Creating Maps
  • Open BizTalk Project containing the XSDs
  • Right click on the project and select Add -> New Item.
  • Select Maps in the left pane and Empty Map in the right pane
  • Give a name for the map and click OK
  • It will open a GUI where we can select the source and the destination schema and map accordingly.
  • Refer to the screen shots for more details.
functoids
Functoids
  • Functoids are functions that can be used with mapper.
  • The source data can be applied with functoids and transformed to destination friendly data.
  • Many functions for manipulating strings (concat, uppercase conversion etc), numbers (add,multiply etc), scientific functions (log, exponent etc), database are available.
  • Refer to the tool bar, the violet color box in the grid in the previous picture.
biztalk administration console
BizTalk Administration Console
  • Administration console is used for performing administrative tasks like
    • Starting and stopping an application
    • Taking reports concerned with messages transferred, application usage etc
    • Configuring send and receiving ports
    • Adding resources to the application
    • Managing Orchestration, Maps, Schemas, Pipelines for the application
biztalk application
BizTalk Application
  • Feature of biz talk server that helps in deployment, management, trouble shooting of biz talk server solutions
  • Logical grouping of artifacts
    • Biztalk and .Net assemblies
    • Send ports, groups
    • Receive ports, locations
    • Policies
    • Certificates, scripts, COM Components
    • BizTalk specific resources (schema, map, orchestration, pipeline)
orchestrations
Orchestrations
  • To add orchestration for a biz talk project, right click on the project and select Add -> New Item
  • Select Orchestration from the left pane and empty orchestration from the right pane
  • Give a name for the orchestration and click OK
  • A new orchestration designer with a file extension odx is opened.
  • Use the tool bar to add components that we want.
pipelines
Pipelines
  • To add pipelines for a biz talk project, right click on the project and select Add -> New Item
  • Select Pipelines from the left pane and either send pipeline or receive pipeline from the right pane
  • Give a name for the pipeline selected and click OK
  • A new pipeline designer is opened.
  • Use the tool bar to add components that we want.
receive pipeline
Receive Pipeline
  • This is for transforming data at the receiving end
  • It has
    • Decoder – to decode the incoming data (MIME decoder)
    • Disassembler – to convert data (flat file or any) to XML
    • Validator – to validate the generated XML against a schema (XSD)
    • Party Resolver – To determine identity of party from who the message is received.
send pipeline
Send Pipeline
  • This is present at the sending end for transforming the outgoing message
  • It has
    • Pre assembler – optional component containing custom tools
    • Assembler – Converting XML data to destination data
    • Encoder – To encode the outgoing data
human workflow services
Human Workflow Services
  • This is for dynamically configuring workflow
  • We can define constraints and lot of other condtions and design the workflow.
  • HwsDb stores details about workflow.
  • Refer to screen shots in the following slides for more details about Human Workflow Services
business rule composer
Business Rule Composer
  • This is used for composing business rules
  • We can set an action to be performed upon an occurrence of an event
  • Actions are evaluated based on the facts (rules)
  • We can compose vocabulary (definitions) or policy (logical grouping of rules) using business rule composer.
