Hi,
There are three basic styles of modeling of which I am aware.  You should choose to study the one most pertinent to your field of work: entity modeling, object modeling, data vault modeling.  I prefer entity modeling for corporate work.  Object modeling is used for many "standards body" work, specifically HL7 healthcare for my field.  I find data vault modeling of very limited use.
With in entity modeling there is "normalized" vs. "dimensional".
I began learning by reading Bill Inmon, Ralph Kimball, and Len Silverston.  I advanced my training by reading models created by experienced people here at Teradata.
I know a few places to get started...
Len Silverston has lots of good information including videos on Youtube and at http://www.univdata.com/
I like the intro material by Missy Wittmann at:

Once you have a good handle on 3NF (Third Normal Form) modeling then looking up Ralph Kimball for dimensional modeling.  That is another step in modeling which creates reporting models for end user access.

DAMA (Data Management International) is my prefered professional group for data modeling meetings.  http://www.dama.org/i4a/pages/index.cfm?pageid=1
TDWI is also good and has lots of educational material.  http://tdwi.org/Home.aspx
