Complexities with WebSpeed

• Non-4GL expertise needed (HTML,JavaScript,...)

• Testing/Debugging– White screen (severe error, server-log)– Restart of Agents (to pick up changed programs)

• “Stateless” client– context management– Flat character-only data-structure (name-value pairs)


Tasks of Framework

• Converts name-value pairs into temp-table

• Requires data for HTML page in temp-tables

• Merges data with HTML page template (plain text)

• Sends merged page to web-stream (i.e. WebServer)

• ... or to a file (for testing purposes)

Issues With WebSpeed

• Did record change since page was prepared?– Additionally sending complete record to page

• So it can be retrieved as “before image” record

– Using “version” field

• Total disconnect between preparing page and next post– ProDataSet content lost– No before-image temp-table possible– Standard ProDataSet update feature can't be used
