- 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.arrow_forwardStep-by-step instructions on how to do data analysis are provided here.arrow_forwardDatabase System Data queries are Consider the System Description to reply the following queries, keeping in view the above mention system description title as “Dream Home branch offices case study”.

- A derived attribute can be stored in a table or calculated on each occasion that it is required. An example of a derived attribute is your Grade Point Average which is calculated by adding together a score for each unit (e.g., HD=4, D=3, C=2, P=1, N=0) and dividing that by the number of units you have completed. Explain how the decision as to whether the Grade Point Average would be stored in a table or calculated would be made. You are administering a database in a large retail company that records sales at each of the company’s stores. Tuning the database to improve performance by adding indexes and optimising query execution is an important ongoing aspect of the physical database design. Which attributes in a database such as this (apart from the primary key) are likely to BENEFIT from being indexed? Which attributes would you generally avoid indexing, and why?arrow_forwardPlease clear and correct answer.arrow_forwardCreeate the ERD to show the relationships among EMPLOYEE, STORE, and REGION.arrow_forward
- Using Figure P7.1 in the text as a guide, write the SQL/DDL to create the Job and EMPLOYEE tables. Note the cardinality requirements for the relationship indicates a foreign key and values are required. Write the SQL commands to add the first three records to the JOB table and the first three records to the EMPLOYEE table. a. What happens if you create the EMPLOYEE table before the JOB table? Why? b. What happens if you add an employee record with a JOB _CODE not present in the JOB table? Why?arrow_forwardWhen doing an analysis, how important is it to use data modeling?
