B Present a detailed data model for the project

Microsoft Visio, which you will have access to
through iLab and Microsoft Excel, which comes
with Microsoft Office. Other tools may be used as
long as the output is legible and conforms to
standard format. (i.e. I will not be able to
grade the data model if I cannot tell what it is
supposed to be!). Your data model should include
a minimum of an ERD and metadata chart (data
dictionary).

A B O V E R V I E W Scenario/Summary There is a
lot more to a database than just tables and the
data in them. A very important part of database
security has to do with using and understanding
Database Views. Being able to enhance the
efficiency of the database tables by using
additional indexes is also a very important
aspect of database development. Finally, being
able to create and use Database Sequences to
automate some of the sequential processes in the
database can not only save time but improve
efficiency.
