BizTalk Components

BizTalk Server 2006 Messaging Engine

Business Rules Engine Health and Activity Tracking

Business Activity Monitor

Business Activity Services

Orchestration

Enterprise Single Sign-On

Messaging


Business Rules Engine

• Let you apply business rules against message data.– For rules creation use: the Business Rule Composor.


Orchestration

• Graphical interface for routing, evaluation and manipulation of incomingand outgoing messages

• Allows for communicationwith web services, databases, ..

• BizTalk OrchestrationDesigner: a tool for creating visualrepresentations of business processes


Health and Activity Tracking

• Used for monitoring the BizTalk Messaging Engine and the orchestrations running in it


Business Activity Monitoring

• Also called BAM, gives nontechnical personnel a portal to view the data


Business Activity Services

• Functionality for managing and instantiatingintegration relationships with trading partners


Enterprise Single Sign-On

• Process for by which non-Windowsauthentication accounts can be granted or denied rights


Messaging

• MessageBox– Based on SQL Server Database– Publish and subscribe pattern

• Involves ports, adapters, pipelines, orchestrations– For maniplation and routing of message data

• XML based– XML Schema Definition

• One of the core components of BizTalk


Messages

• Trading part message– File: comma-separated values (CSV) text, HTML, ..– Must be converted to XML in order for BizTalk to manipulate,

route, modify the message


Pipeline

Typical functions performed in a receive pipeline: • Decoding and parsing of incoming data such as an XML file or a flat file• Disassembler; splits message if necessary• Validation; for example, verifying the incoming data against an XML schema • Party resolution; resolves host instance

Typical functions performed in a send pipeline: • Validation• Assembly of an XML document• Encoding• Digital signing


Pipeline Editor

• Graphicalinterface for convertion of filesto meet the XML requirements


Schema Editor

• Schema editor for generating the structure/format and the rules for your XML files


BizTalk Mapper

• Graphical interface for mapping an incoming file to your own XML schema


BizTalk Mapper cont´d

Integrating mutiple applications


Running ExampleThe example on the this slide and next two are from: Microsoft BizTalk Server 2006An integration and business process serverBy Nico Naumann


Running Example cont´d


XML by way of W3School.com

• EXtensible Markup Language– Much like HTML– Describes embedded or referenced data– XML tags are not predefined

• You define your own

– XML uses a Document Type Definition (DTD) or an XML Schema to describe the data

– XML with a DTD or XML Schema is designed to be self-descriptive

– XML is a W3C Standard


Difference between XML and HTML

• XML and HTML were designed with different goals:– XML was designed to describe data and to

focus on what data is.HTML was designed to display data and to focus on how data looks.

• HTML is about displaying information, while XML is about describing information.

XML Syntax

• The first line in the document - the XML declaration - defines the XML version and the character encoding used in the document

• The next line describes the root element of the document (like it wassaying: "this document is a note")

• The next 4 lines describe 4 child elements of the root (to, from, heading, and body)

• And finally the last line defines the end of the root element

<?xml version="1.0" encoding="ISO-8859-1"?>

<note> <to>Tove</to> <from>Jani</from> <heading>Reminder</heading> <body>Don't forget me this weekend!</body> </note>

XML Rules

• All XML elements must have a closing Tag– The declaration is NOT a part of the XML document itself, and

thereby does not need a closing tag

• Tags are case sensitive– <Letter> != <letter>

• XML elements must be properly nested– This text is bold and italic NOT OK– This text is bold and italic OK

• XML documents must have a root element– All elements can have sub element. Sub elements must be

correctly nested within their parent element


XML Rules cont´d

• Attribute values must be quoted– With XML, it is illegal to omit quotation marks

around attribute values

• Whitespaces are preserved– Unlike HTML


Exercise

• Make an xml-file describing this book.

My First XML

Introduction to XML

•What is HTML •What is XML

XML Syntax

•Elements must have a closing tag•Elements must be properly nested

XML Attributes

• Data can be stored in child elements or in attributes– Attributes are used to describe overall facts of the element and

nested elements

<person sex="female"> <firstname>Anna</firstname><lastname>Smith</lastname> </person>

<person> <sex>female</sex> <firstname>Anna</firstname> <lastname>Smith</lastname> </person>


XML Attributes vs. Elements

• There are no rules. However..• Some of the problems with using attributes are:

– attributes cannot contain multiple values (child elements can) – attributes are not easily expandable (for future changes) – attributes cannot describe structures (child elements can) – attributes are more difficult to manipulate by program code– attribute values are not easy to test against a Document Type

Definition (DTD) - which is used to define the legal elements of an XML document

• The exception could, for example, be when dealing with metadata.– Like when you have an ID for an element


XML Errors

• The W3C XML specification states that a program should not continue to process an XML document if it finds an error.

– The reason is that XML software should be easy to write, and that all XML documentsshould be compatible


XML Schema

• Describes the structure of an XML document– No content data

• The XML Schema language is also referred to as XML Schema Definition (XSD)

• W3C Standard

• XML Schemas are written in XML


What exactly is an XML Schema?

• The purpose of an XML Schema is to define the legal building blocks of an XML document

• An XML Schema defines: – elements that can appear in a document– attributes that can appear in a document– which elements are child elements – the order of child elements – the number of child elements – whether an element is empty or can include text – data types for elements and attributes– default and fixed values for elements and attributes

XML Schema Example

<?xml version="1.0"?> <note> <to>Tove</to> <from>Jani</from> <heading>Reminder</heading> <body>Don't forget me this weekend!</body> </note>

XML-file

XML Schema Example cont´d<?xml version="1.0"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.w3schools.com" xmlns="http://www.w3schools.com" elementFormDefault="qualified">

<xs:element name="note"> <xs:complexType>

<xs:sequence> <xs:element name="to" type="xs:string"/><xs:element name="from" type="xs:string"/><xs:element name="heading" type="xs:string"/><xs:element name="body" type="xs:string"/>

</xs:sequence> </xs:complexType>

</xs:element>

</xs:schema>


Complex and Simple Types

• Complex types– Can have nested elements as well as attributes– The note element is a complex type because it

contains other elements

• Simple types– Cannot have nested elements or attributes– The other elements (to, from, heading, body) are

simple types because they do not contain otherelements


Sequence

• The elements surrounded by this tag needto be sent in the same order as shown in the schema


Element types

• XML Schema has a lot of built-in data types. The most common types are: – xs:string

– xs:decimal– xs:integer

– xs:boolean– xs:date

– xs:time

XML Schema Rules

• The <schema> element is the root element of every XML Schema – may contain some attributes– xmlns:xs=http://www.w3.org/2001/XMLSchema

• Indicates that the elements and data types used in the schema come from the "http://www.w3.org/2001/XMLSchema" namespace

• Also specifies that the elements and data types that come from the "http://www.w3.org/2001/XMLSchema" namespace should be prefixed with xs:

– targetNamespace="http://www.w3schools.com" • Indicates that the elements defined by this schema come from the

"http://www.w3schools.com" namespace

– xmlns=http://www.w3schools.com• Indicates that the default namespace is "http://www.w3schools.com"
