XML and Related Technologies ( Test 141 )

Exam Objectives and Sub-Objectives:

Following are the objectives of this exam

1. Architecture

• Determine the implications of a given architecture on XML design considerations
• Select appropriate XML technologies for an architecture (XML Schema 1.0, XSLT 1.0, DOM2, SAX2, XPath 1.0, Namespaces, DTDs)
• Design functional components and interconnections for an XML application architecture
• Assess performance trade-offs related to parsing, validation and transformation
• Know basics of Web Services (SOAP, WSDL, UDDI)
• Address XML security using XML encryption and XML signature

2. Information Modeling

• Analyze data, documents, and problem domains
• Represent structure in XML syntax (model data)
• Use Namespaces appropriately
• Define DTDs (declarations, reuse, external references)
• Define schemas using XML Schema (declaration, structure, data types, data relationships, reuse, external references)
• Determine when to use DTD versus XML Schema (legacy systems, scoping, run-time modification, constraints)
• Consider data integration and linking issues when designing data models (i.e., related to XLink/XPointer)
• Perform validation of XML documents  

3. XML Processing

• Analyze data integration points
• Use the SAX2 API to manipulate XML data
• Use the DOM2 API to manipulate XML data
• Traverse an XML document using XPath
• Transform XML using XSLT
• Determine process implications when integrating XML data
• Address validation/conformance and exception handling issues related to XML Schema (e.g., data typing and pattern matching)

4. XML Rendering

• Define optimal rendering/transformation approach for each target (e.g., screens, print, pervasive)
• Use XSLT and Formatting Objects to style XML documents
• Re-target XML for multiple formats
• Use existing CSS to format XML or XHTML
• Consider data rendering issues after designing data models

5. Testing & Tuning

• Determine appropriateness of single versus multiple pass transformations, XSL extensions, XSL and Schema inclusions
• Optimize XML application execution (e.g., includes, import, id, idref, keys)
• Create instances for testing XML applications (e.g. based on data model, boundary cases)
• Refine design as necessary based on data model, data integration, data rendering, and data query issues
