I wouldn't mind a database interface, but I don't want your SQL stuff,
my preference is Codasyl.

For tasking, such religious issues do not exist, and implementations
of Ada must coerce the environment into supporting the Ada model.
It is unlikely that Ada has anything grand to offer the database
community, so binding to existing standards is better.
