Description
Unit 6 Assignment 2
Application 2:
Database Design
When you design a system, how its data is
stored, optimized, and accessed are among your primary concerns. If your system
cannot work efficiently with well-structured data, then your design would not be
of much use to your organization.
For this Application, imagine that you are a
systems analyst for a bookstore. You are designing a system to sell books, CDs,
and DVDs online. Using what you have learned about data management layer
design, address the following in a 2- to 3-page paper:
·
Which
object-persistence format is best for this system?
·
How do the
problem-domain classes map to the selected format?
·
What techniques would
best optimize the design’s processing efficiency?
·
What do you need to
consider when you design the data access and manipulation (DAM) classes for the
system? Create one DAM class as an example.
·
Explain each of your
recommendations and justify the design choices.
Cite your sources according to APA guidelines.
Submit your assignment by Day 7.
