Designing a Physical Model Only,full set of options for Physical model design implementation, you should always carry out the Conceptual/ Logical/Physical model design methodology outlined earlier in this book. Don’t rush straight to the Physical model design; this approach is always to be a “make-do” approach to data modeling.

Communicating with the Model, any security and access requirements. This may involve models being published on a company intranet or the creation of a central model repository. Creating a repository makes for improved reuse of existing models and, as a result, more efficient management of data elements (and their subsequent growth) within a given enterprise.

Improving Data Quality and Managing Documentation,tween your models and other documentation, organizations, and requirements. Keeping this type of information in mapping documents is a stopgap measure that you’ll have to continue until metadata management becomes an integral part of your enterprise. In discussing mapping documents, you looked at many different examples, including the following:

Rudra Pratap,Yash K. Dungerpuriahe process of normalization, which is verifying the relational nature of your data organization against the various degrees of normal form. We covered 1NF, 2NF, 3NF, and BCNF and showed how they help you verify the following:.You then looked at the power and risks of denormalization, the process by

In Pursuit of Quieter Ship Design,ok. Many of the concepts that the symbols represent are the same. Although some symbols are unique to one style or another, the higher-level concepts are largely independent of the graphic symbol sets used in these languages. The symbols cover notations for many different aspects of set members and

You looked at what you can do to improve upon existing Physical model designs, prior to their implementation, in order to ensure that the application being developed not only runs
