I have no idea about querying syntax, but implementation-wise, it would just be:

1) a reverse look up in the “Name column” table: get Row-ID for value = “Dave”;
2) a forward look up in the “Birthdate column” table: get value where Row-ID = xxx;

I am guessing both look ups will be fast because of indexing.

How do you tell when Dave's birthday is or is that a bad question to ask a column oriented database?

Here’s an explanation of the difference between a column-oriented approach and vertical partitioning.http://www.databasecolumn.com/2008/07/debunking-another-myth-columns.html

I still don’t see the difference between a column-based DBMS and a DBMS which supports vertical partitioning?
