关于IBM XML认证考试的要点
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)
