關于IBM XML認證考試的要點

　　Individuals who successfully complete Test 140, XML and Related Techno

　　logies, V1 Test, will have demonstrated the knowledge and skills assoc

　　iated with the following XML developer-related tasks:

　　1.Design

　　Determine the implications of a given architecture on XML design con

　　siderations

　　Determine how W3C recommendations will be applied (e.g. determine wh

　　en DOM is appropriate, etc.)

　　Use the details and syntax of core W3C recommendations (XML, XSL, DO

　　M, XPath, namespaces, DTDs, XML well-formedness)

　　Identify what features of XML are W3C recommended and standardized i

　　n order to develop a W3C-compliant application

　　Given an architecture, design functional components

　　Given an architecture, define interconnections among functional components

　　Given an architecture, select appropriate tools/libraries

　　Refine design as necessary based on data model, data integration, da

　　ta rendering, and data query issues

　　2.Information Modeling

　　Analyze data/documents for structure

　　Represent structure in XML form

　　Define DTDs

　　3.XML Processing

　　Identify points of data integration

　　Define the optimal integration approach at each point (e.g., XSL tra

　　nsformation and DOM)

　　Establish linking relationships

　　Consider data integration and linking issues when designing data models

　　4.XML Rendering

　　Identify rendering/transformation targets (e.g. web pages, print, pe

　　rvasive, etc)

　　Define the optimal rendering approach for each target

　　Consider data rendering issues when designing data models

　　5.XML Query

　　Identify data to be retrieved for resulting subset of data

　　Define the optimal retrieval approach for each dataset

　　Consider query constraints when designing data models (e.g. metadata

　　, inner structure, additional attributes)

　　6.Implementation/Testing

　　Determine optimal development environment using standard tools as ap

　　propriate (e.g. DTD editors, XSL and style sheet editors, XSL debugger

　　s, XML editors)

　　Determine best use of APIs to XSL processors & XML processors

　　Assess performance tradeoffs

　　Implement a given design (including the data model, data integration

　　, data rendering, functional components, & interconnections among func

　　tional components)

　　Create instances to test (e.g. based on data model, boundary cases)

　　Address exceptions (e.g. parser and DOM errors)
