What Is XML ?eXtensible Markup Language is a set ofspecifications from the World Wide WebConsortium (W3C)XML is a" set of rules that defines what a validmarkup tag is" method for putting structured data into atext file" family of “vocabularies” that provide setsof tags or guidelines for specific industries" subset of SGML

What’s so great about XML?"""""The data is self-describingFlexible way of representing dataPlatform and device independentLeverages the InternetWidely accepted standard

Example: Self-describing dataData stream in a typical interface “ABC47-Z”, “100”, “STL”, “C”, “3”, “28”Same data stream in XML Inventory PartNum ABC47-Z /PartNum Quantity 100 /Quantity Warehouse STL /Warehouse Zone C /Zone Aisle 3 /Aisle Bin 28 /Bin /Inventory

Electronic DataInterchange (EDI)"Standards based (ANSI X12 andUN/EDIFACT) application toapplication transfer of businessdocuments between computers andbusiness partners"Over 90% of Fortune 1,000 firmsuse EDI"But only 5% of smaller firms do

Problems with EDI!!!!Messages are difficult to decipher.Needs dedicated EDI server and VAN.Costly to implement and maintain.Compatibility between X12 and EDIFACTnot good.
