Perl Programming

Big Data Datacenter was impressed with your previous examples of system commands and is now looking at the project from a more strategic approach. The team is looking at you to show the big picture and explain how everything will work together. The requirement is an analysis on the following:

• Identify modules from CPAN that can support a graphical user interface (GUI), network protocol, and database adapters. In your analysis, demonstrate how these modules will make interacting with the system more human-friendly in support of maintaining servers in the data center.
• Describe how you will practically interact with CPAN to install the modules that you have identified.
• Provide the syntax to create your own custom module that lends itself to being reused. Because the company is focused on managing servers, you might consider a module based on the following examples, but you are free to create your own:
  • Executes system commands to retrieve system metrics like CPU utilization
  • Reads information from a flat file and then inserts into a database
  • Connects to a database and retrieves reporting information
