Model Generation

lDesign pattern – Given a model, generate an equivalent model in another metamodel

map

lApplications

ØWrapper generation (SQL ® OO or XML)

ØDesign tools (ER ® SQL, SQL ® ER)

ØUI/4GL generation

lSolution template

ØáM2, mapñ = ModelGen(M1, metamodel2); Export(M2)

ØModelGen often needs human guidance


	SM: actually, ModelGen executes a functional meta-mapping between two meta-models. Output is a target model + mapping between source and target: <target, map> = ExecuteMapping(source, meta-map);
	Examples:
	execute meta-mapping (rules):<SQL, map> = ExecuteMapping(ER, rules);
	execute mapping: <XSD2, instance map> = ExecuteMapping(XSD1, xslt);
