mysql - best way to combine two tables that have same columns and different values -


i have problem finding best way combine 2 of tables in sql.
have 2 user-feature tables below same columns different values:

2 table represent user-feature profile of user , generate different sources need combine single user-feature table , dont know if data user(i) table1 more authentic or table2.
think best way combine 2 table?
example should use mean value or max-min or there better way?

table1:  user   feature1    feature2         2          8  b        4          3  c        1          6 

table2:

user   feature1    feature2         3          6  b        2          4  c        4          8 

you're going have @ code uses these tables , see how differs

maybe 1 table isn't used more

maybe 1 table setting user interface features , other setting data processing features (in case make 1 table called features 4 columns called uifeature1, uifeature2, dpfeatire1, dpfeature2

essentially here have asked question no 1 on internet can answe you; you're going have research yourself
