  1. Using XML Transactions Presented By Tony Alwardt The Boeing Company

  2. Introduction • Provides a common dialect to be used between two are more parties

  3. Benefits • Fewer Schemas to Maintain and Develop Against • Schema performs initial required data validation instead of application software • Transactions give XML tags context sensitive meaning • System integrators only deal with transactions they require • The ability to tie requests and responses together • Provides built in error elements for every transaction • Readily supports Synchronous & Asynchronous Communication • Readily supports Batch Processing • Supports Passing Application Level Security Credentials

  4. System 2 System 1 System 3 Multiple Schemas XML Transaction Type 1 Request XML Schema 1 XML Transaction Type 1 Response XML Schema 2 XML Transaction Type 2 Request XML Schema 3 XML Transaction Type 2 Response XML Schema 4

  5. System 2 System 1 System 3 Integrated Schema XML Transaction Type 1 Request XML Transaction Type 1 Response Integrated XML Schema XML Transaction Type 2 Request XML Transaction Type 2 Response

  6. System 2 System 1 Validation (Traditional Schema Use) Schema verifies that the XML document is in the correct format. XML Document XML Schema Software verifies that the XML document contains the appropriate requiredXML elements/attributes. Software Library

  7. System 2 System 1 Validation (Transaction Schema Use) Schema verifies that the XML document is in the correct format and that the required XML elements/attributes exist. XML Document XML Schema This block is potentially no longer required. Software Library

  8. Context Sensitive Meaning Add Work Orders Transaction <?xml version="1.0" encoding="utf-8"?> <TxDML version="1.0" xmlns:bc="http://www.companyA.com/ATML/schemas/Common" xmlns="urn:DML-TxDML-Schema"> <TxRequest> <AddWorkOrders> <WorkOrders> <WorkOrder status="Open" openedDateTime="2004-06-03T07:36:31"> <bc:MasterKey>JCNARN001</bc:MasterKey> <Platform name="F/A-18" model="E" serialNumber="111111"/> <WorkItems> <WorkItem status="Open" openedDateTime="2004-06-03T07:36:31"> <bc:Site name="St. Louis"/> <bc:MaintenanceLevel abbr="O"/> <UUT type="WRA"> <bc:PartNumber>Demo 2005</bc:PartNumber> <bc:SerialNumber>SN0001</bc:SerialNumber> <bc:Manufacturer>MAN001</bc:Manufacturer> </UUT> <TestPrograms> <TestProgram name="Demo2005 TPS" type="XML"> <TestResults outcome="Failed"> <TestGroup outcome="Failed" bc:startDateTime="2002-04-14T17:16:25.500"> <Observables> <Observable name="Altitude" value="0.000" type="Decimal" units="Feet"/> <Observable name="NormalAcceleration" value="-35.313" type="Decimal" units="FPS Squared"/> </Observables> <Test name="000" outcome="Failed" type="MSP" descr="RADAR ANTENNA FAIL"/> <Test name="111" outcome="Failed" type="MSP" descr="GYRO TEST SKPD"/> </TestGroup> </TestResults> </TestProgram> </TestPrograms> </WorkItem> </WorkItems> </WorkOrder> </WorkOrders> </AddWorkOrders> </TxRequest> </TxDML>

  9. Context Sensitive Meaning Update Work Orders with Indictments <?xml version="1.0" encoding="utf-8"?> <TxDML version="1.0" xmlns:bc="http://www.companyA.com/ATML/schemas/Common" xmlns="urn:DML-TxDML-Schema"> <TxRequest> <UpdateWorkOrders> <WorkOrders> <WorkOrder status="Open"> <bc:MasterKey>JCNARN001</bc:MasterKey> <WorkItems> <WorkItem status="Open"> <bc:MaintenanceLevel abbr="I"/> <UUT type="WRA"> <bc:PartNumber>Demo2005</bc:PartNumber> <bc:SerialNumber>SN0001</bc:SerialNumber> </UUT> <TestPrograms> <TestProgram name="Demo2005 TPS" type="XML"> <TestResults outcome="Failed"> <TestGroup outcome="Failed" bc:startDateTime="2005-04-12T13:00:07.000"> <Test name="300.00" outcome="Failed" type="T" descr="Resister A Check"/> </TestGroup> <Indictments retestEntryPoint="300.00" indictmentsID="3" indictmentsDateTime="2005-04-12T13:00:07"> <Indictment repairType="R" repairDescr="Remove and Replace"> <UUT> <RefDes>A1</RefDes> </UUT> </Indictment> </Indictments> </TestResults> </TestProgram> </TestPrograms> <bc:TestStation type="STATION A"/> </WorkItem> </WorkItems> </WorkOrder> </WorkOrders> </UpdateWorkOrders> </TxRequest> </TxDML>

  10. Context Sensitive Meaning Update Work Orders with Repairs <?xml version="1.0" encoding="utf-8"?> <TxDML version="1.0" xmlns:bc="http://www.companyA.com/ATML/schemas/Common" xmlns="urn:DML-TxDML-Schema"> <TxRequest> <UpdateWorkOrders> <WorkOrders> <WorkOrder status="Open"> <bc:MasterKey>JCNARN001</bc:MasterKey> <WorkItems> <WorkItem status="Open"> <bc:MaintenanceLevel abbr="I"/> <UUT type="WRA"> <bc:PartNumber>Demo2005</bc:PartNumber> <bc:SerialNumber>SN0001</bc:SerialNumber> </UUT> <bc:TestStation type="STATION A"/> <Repairs> <Repair repairType="S" repairDescr="Remove and Reinstall" repairIndictmentsID="3"> <UUT type="SRA"> <bc:PartNumber>CARD001</bc:PartNumber> <bc:SerialNumber>TRFDV</bc:SerialNumber> <bc:RefDes>A1</bc:RefDes> </UUT> </Repair> </Repairs> </WorkItem> </WorkItems> </WorkOrder> </WorkOrders> </UpdateWorkOrders> </TxRequest> </TxDML>

  11. Easier Integration via Transactions Example: 5 Available Transactions <TxDML version="1.0"> <TxRequest> <AddWorkOrders></AddWorkOrders> <UpdateWorkOrders></UpdateWorkOrders> <GetSuggestedCallouts></GetSuggestedCallouts> <GetSuggestedEntryPoints></GetSuggestedEntryPoints> <GetWorkOrders></GetWorkOrders> </TxRequest> </TxDML> 3 Transactions Used by User 1 2 Transactions Used by User 2 <TxDML version="1.0"> <TxRequest> <AddWorkOrders></AddWorkOrders> <UpdateWorkOrders></UpdateWorkOrders> <GetWorkOrders></GetWorkOrders> </TxRequest> </TxDML> <TxDML version="1.0"> <TxRequest> <GetSuggestedCallouts></GetSuggestedCallouts> <GetSuggestedEntryPoints></GetSuggestedEntryPoints> </TxRequest> </TxDML> User 1 User 2

  12. <TxDML version="1.0"> <TxRequest> <GetWorkOrders> <MasterKey>Master Key XYZ</MasterKey> </GetWorkOrders> </TxRequest> <TxResponse> <TransResult> <ResultCode tc="Success "></ResultCode> <WorkOrder> <MasterKey>Master Key XYZ</MasterKey> </WorkOrder> </TransResult> </TxResponse> </TxDML> Request Response Request/Response Model • Supports echoing the request in the response (Especially useful with asynchronous systems)

  13. Error Processing • Required “ResultCode” element exists in every transaction response <TxDML version="1.0"> <TxRequest> <GetWorkOrders> <MasterKey>Master Key XYZ</MasterKey> </GetWorkOrders> </TxRequest> <TxResponse> <TransResult> <ResultCode tc="Failure"> <ResultDesc>Communication Error.</ResultDesc> </ResultCode> <WorkOrder> <MasterKey>Master Key XYZ</MasterKey> </WorkOrder> </TransResult> </TxResponse> </TxDML> Result Info

  14. System 2 System 1 Synchronous vs. Asynchronous Processing • Readily supports Synchronous & Asynchronous Communication Synchronous Communication XML Document XML Document

  15. System 2 System 1 Synchronous vs. Asynchronous Processing • Readily supports Synchronous & Asynchronous Communication Asynchronous Communication XML Documents XML Documents Echoing the initial request with the response enables Asynchronous Communication.

  16. System 2 System 1 Batch Transaction Processing • Readily supports Batch Processing XML Requests XML Responses The schema can support sending multiple request transactions in one XML Document. The same applies for response transactions.

  17. Application Level Security Credentials • Application Level Security Credentials can be included in a Request Transaction. <TxDML version="1.0"> <UserAuthRequest> <UserLoginName>String</UserLoginName> <UserPswd> <CryptType>String</CryptType> <Pswd>String</Pswd> </UserPswd> <UserDomain>String</UserDomain> <UserDate>1967-08-13</UserDate> <UserTime>14:20:00-05:00</UserTime> </UserAuthRequest> <TxRequest> <GetWorkOrders> <MasterKey>Master Key XYZ</MasterKey> </GetWorkOrders> </TxRequest> </TxDML> Security Info
