Goal Find the names of views and materialized views that have prefix or suffix. Follow the same naming style as in case of base tables (derived tables are also tables). Thus, if base tables do not have prefixes or suffixes, then derived tables shouldn't have these as well.
Type Problem detection (Each row in the result could represent a flaw in the design)
Reliability Medium (Medium number of false-positive results)
License MIT License
Fixing Suggestion Rename the derived table so that it does not have prefix and suffix.
