I need to cluster my data, but there are multiple ways to view the data such that I can't really place it all into a single table. I have been working with Open Refine to cluster this data but I keep running into a limitation.



I have two tables that share a common column ID. The first table is a list of cars:



CarId | Make | Model | Year | 
0 | Toyota | ... | 2018 |
etc ...


And a second table:



CarId | Part | Color | Weight | 
0 | Driver Door| Green | 123 |
etc ...


So Open Refine only works with a single table of data at at time. This is an issue because obviously the data I want to cluster by is in two different tables.



How would I be able to ask, say, show me all cars that don't have a Green Driver Door, or all cars that do have a Green Driver Door?



I could join these all into a single table using an SQL join, but what if the data set doesn't practically fit into a single table? I could "ask the question" by using an SQL query, but at that point I am not interactively clustering with open refine, I have to go back to sql and re-export the data whenever I want to ask a different question...



Thanks!
