what is the difference between logical model and and conceptual model

Answer Wiki

Thanks. We'll let you know when a new response is added.

In general, the conceptual model is built before the logical model, and it is more abstract, including only the most important entities/relations.

Some information can be found <a href=”http://www.1keydata.com/datawarehousing/data-modeling-levels.html”>here</a> and <a href=”http://www.aisintl.com/case/CDM-PDM.html”>here</a>

Hope this helps.
