Background: I go through many articles those stating that if you want to use relations, joins and want to use large scale site (with millions of records) than use Database Tables. It is good till Sharepoint2010
Now seeing at this details http://technet.microsoft.com/en-us/library/cc262787.aspx I found that limits are exceed to millions of items for list. Now can you please guide if i use large scale database site (suppose i am making social media site like FB which contains lot of 1000s queries with joins, relationships are there etc ) than should i choose list or go to external database ..
Suggestion are highly appreciated .. Please mention with reason, logic and also refer some authentic material so that i can convince my seniors
Thanks in advance.
