I'm working for a business lender, and trying to come up with a basic dimensional model around the subject area of loan approvals.

We use a CRM, (Salesforce) and one of the core objects is a (Sales) "Opportunity". Sales usually start off as a lead, if we get traction on a lead, we will create an account, at least one contact, and an "Opportunity" which is a potential loan (our business calls it a "Deal"). All of the loan approval process happens under a particular "Opportunity". I know that Account and Contact would be good dimension candidates, I am unsure of Lead and Opportunity though.

I'm interested in opinions on which category Leads and Opportunities belong in: Fact or Dimension?

Here is an example of some opportunity fields that may be relevant to a data warehouse:

    CREATE TABLE
      dbo.Opportunity
        (
            OpportunitySK                       BIGINT        NOT NULL
                                                IDENTITY(1,1)
                                                CONSTRAINT 
                                                  PK_dbo_Opportunity
