All of the Following Are Reasons That Having Separate Files

All of the following are reasons that having separate files for each DSS application is wasteful, expensive and inefficient, except ____.

A) having separate files for each DSS application interferes with the transactional database environment by compromising its performance
B) different DSS applications often need the same data, causing duplicate files to be created for each application
C) while particular files support particular DSS applications, they tend to be inflexible and do not support closely related applications that require slightly different data
D) individual files tied to specific DSS applications do nothing to encourage other people and groups in the company to use the company's accumulated data to gain a competitive advantage over the competition
E) even if someone in the company is aware of existing DSS application data that they could use to their (and the company's) own advantage they generally can't get access to it because it is "owned" by the application for which it was created
