The invention discloses an analysis method for a database physical model. The analysis method comprises the steps of obtaining a database physical model file to be analyzed; converting the database physical model file to a XML file; parsing the XML file, counting similar tables in the XML file, and counting similar field length difference information in the similar tables; therefore, in the analysis method for the database physical model, the similar tables and the field length differences of the similar tables can be counted by the analysis of the database physical model in order to have a clear understanding of the whole database in the early stage of a project, a series of incalculable costs resulting from late rectification due to database design flaws are avoided; the invention also discloses an analysis system for the database physical model, which can also achieve the above technical effect.
