One example of Normalization is the class webpage. The page allows both Prof. Yao and the students access to data in an organized fashion. It allows for a reduction in redundancy, and puts the data in one central bucket.

Alex,

One issue with Android phones, and google software is that it is “Open Source”. Which means the code is made public and can be modified by anyone. This means, a person can create a “flashlight” app for the android and hide malicious code within the application and you would never know.
