Found my petition in list - not sure of what it means

I searched for my employers on an on-line list of petitions filed (VisaDoor.com) and by chance found my individual info - this was written on that site about my petition:

ID no. I********

Submit date: *****

Decision date: 3/10/14

Status: certified

Does this mean anything or is it just confirming I’ve been filed?

Are you talking about your LCA or H1B Petition ? Did you file it in this year’s FY 2015 quota ?

The info that you see on that site is just the LCA information and does not tie back to USCIS H1B Receipt number.
