The processes used to complete a data science project vary in their number of steps and functions, but in the end, the objectives and outcomes are similar.
Research on the Web to identify what you believe to be the set (version) of steps that you'd use to complete a Data Science project. You should find versions with 5, 7, 9, 11, 12, or more steps. If you choose a particular set of steps, cite your source and explain why you would use that approach. If you wish, you can develop your own approach, drawing on the research, if you think there may be a better way. As you get deeper into Data Science, in subsequent courses, you should learn the validity of your approach.
List the steps of your approach, cite its source, and provide an explanation of why this particular approach would work best for you.
The management of major-related data is something your department is interested in. Create a data structure that will keep your department's important information current. Of course, the majors list needs to be arranged by last name (and then by first, if there are multiple students with the same last name).
What is the purpose of a data model, and how will it assist us in reaching our objective?
