Give a description of the basic rules that you should follow when making a good data flow map.
If you could provide us with any background information on how to design dependable data input fields, we would greatly appreciate it. There may be instances when deviating from these guidelines is required, but under what conditions?
For the term project, you should write a report on a chosen topic related to your field. Follow the steps below:
Choose a topic : Technology
Narrow it down : Algorithms and data structures
Find at least 10 related articles to your topic
Read the articles, synthesize them and report the parts you want.
Use appropriate citations and quotations (APA 6th or 7th edition)
You need a reference list at the end of your report.
The report should be minimum 1000 and maximum 2000 words.

The company is interested in moving forward with the project, but the senior management team has responded to the presentation with the following questions and concerns: Style: write in third person, no "I" or "we"; "...a study was performed...." Use the bullet separators in your formatting Use IEEE reference style It's really smart to find a reference for each section. These are helpful examples, use them, please: Security: use NIST SP800-53 Think Open Office or Libre for Windows apps Log files, look at NIST SP800-92 Different types of linux, "keyword linux distros" Note: you are writing to Faster Computing's management and not an audience of engineers and administrators.

- What exactly is the meaning of input data validation?arrow_forwardPlease walk us over the fundamental ideas involved in the creation of useful data input fields. Are there any circumstances that come to mind in which you could consider breaking one of these rules?arrow_forwardYou can use the selection structures in this chapter interchangeably for many circumstances. There are a few occasions when one is clearly preferable to another based on input data. Some of these situations were touched on in the switch statement discussion. Review these, give an overview of all of the selection structures discussed in the chapter, and then discuss how to determine which structure to use when there is no clear indication. How much of the choice should be based on personal preference and how much on conventional practices? Are there performance issues as well?arrow_forward
- What is the meaning of input data validation?arrow_forwardIn addition to a variable's name, its "type" and "extra characteristics" must be specified. That is to say, apart from its data type, every variable has its own distinct characteristics. If you could elaborate on the idea so that we could better clarify the terms, that would be great.arrow_forwardQuestion on R Studio Please provide as detailed explanation as possible, with examples if possible.
