Why Meta Data is Important
lMany DB problems
are easier to solve by manipulating meta data
ØInstead of
writing code
ØInstead of
manipulating data directly
lMeta-data-based
solutions all involve models (schemas) and mappings
ØMappings - data
transformations, queries, dependencies, …
ØModel,
manipulate, and generate them
ØUsually,
generate code from them
