As there are many abbrevations used in SQL like
db -> database
tbl -> table
sp -> stored procedure
v -> views
I found a view with the name dbo.v_x_source
Does that 'x' has any particular abbrevation?
While these abbreviations are pretty much standard, sql doesnt stop you from not conforming to these standards.
You can create a table starting with sp and stuff. Your company might have its own set of rules with regards to naming sql objects; you might be able to ask someone with more experience.
Personally, I think that was just named badly.
