 A friend of yours is running his business on what is becoming a more complex linked spreadsheet.  He invited you to assess the situation and propose a solution.  After a thorough study, you have suggested that he start using a database.  How would you justify the use of a database?  He also asked you to explain what he called “buzz words” that are surging the IT field:  

  • What is the difference, in terms of functions and roles, between DBMS and SQL?  
  • Define and explain the difference between database, data warehouse, and big data?

In response to your peers, please fill in any gaps or add more detail to help support their answer, emphasizing the critical features and operations of the relational model and why it is the most popular database model.
