A sequence is an ordered list of objects (or events). Like a set, it contains members (also called elements or terms), and the number of terms (possibly infinite) is called the length of the sequence. Unlike a set, order matters, and exactly the same elements can appear multiple times at different positions in the sequence.

A sequence is any type for which there is a bijective relation between the integers 0..n and the elements of the sequence, and the elements may be accessed in the order 0..n, where n is the number of elements in the sequence.

So *, what is the "correct" definition of a sequence?

Could we split these two out somehow? A few options:

  1. Create , merge everything that is DB related into that and then merge the remainder of and together.
  2. Acknowledge the fact that the mathematical construct, the database object, the type, the collection and the Java class have effectively indistinguishable names and that people will always put questions into the wrong tags.

    Merge these two together and modify the wiki and excerpt to be more encompassing and less exact.

* I can't find the question that asks why so many people start their posts with so; mainly because so many posts have SO in them. sigh

A sequence in f# is an alias for IEnumerable<T> which is probably why you see it with f#. It also has meaning for linq as well so you're right about #2. Its also an autonumber in oracle which is why you see 80 questions of Oracle + sequence. I can't see how anyone who's got a problem with an oracle sequence number would look for or tag it with [database-sequence] – Some Helpful Commenter Jun 15 '12 at 22:27
@SomeHelpfulCommenter, neither can I really, hence the second point suggesting mashing it all together and hoping for the best. I can do that on my own, just wanted some sort of corroboration. – ben is uǝq backwards Jun 15 '12 at 22:30
Those two definitions encapsulate different views of the same abstract idea. – dmckee Jun 15 '12 at 22:48
So what's wrong with searching for Oracle Sequence or F# Sequence? – Robert Harvey Jun 16 '12 at 0:34
@Robert, nothing. I'm asking other people... if merging them is acceptable then great. – ben is uǝq backwards Jun 16 '12 at 8:17
