Description

Add some preprocessing process such as filtering for dimension tables, dimension tables' aggregation to a certain extent to adapt to the granularity of the fact table (avoid many-to-many), deduplication of dimension tables, etc. Logical views are hoped to be capable of being created, maintained in metadata, referenced by models and queryable, as normal views.
