Here are query translator paradigms that can be used with the universal query
translator. (These are included in the webapp distribution.)
Each paradigm implements a different relational database search
strategy for a named bucket type. For example, paradigm Temporal_BeginEnd.py
implements search for the temporal bucket type by translating ADL
temporal query constraints to SQL constraints placed against a
database table containing begin and end date columns.
The Adaptor paradigms are wrappers, and can be used both to modify
and augment other paradigms and to combine multiple paradigms into
one.
