Query Classification

Initial idea

num_variations_query_ran_on_it - num_choices_in_the_query

• num_table - num_joins

S: single

M: multiple

0: not applicable

Notes:

• A good start would be to classify queries based on the number of choices and joins.
• We may want to classify based on nested choices?! do we have types of choices or anything like type of joins?

Query classification of prima:

(num_source_version - num_table - join_type)

S: single M: multiple 0: not applicable T: temporal join only N: non-temporal join only B: both types of joins C1: S-S-0 C2: S-M-T C3: S-M-N C4: S-M-B C5: M-S-0 C6: M-M-T C7: M-M-N C8: M-M-B
