9.3) IDL (Persistent Data Systems) (Commercial Systems - Other Models - Object-oriented Databases And Vendors)
IDL is a schema definition language. Schema modifications are defined
in IDL, requiring ad-hoc offline transformations of the database, in
general. A simple class of transformations can be handled by
IDL->ASCII and ASCII->IDL translators (i.e., integer format changes,
list->array, attribute addition).
