As the head of the DBMS department, you attend a meeting with company managers who are known for their tolerance for the changes in the technology in their company. One of them has heard that non$-$relational$/$nontraditional databases have helped some leading companies to be very successful. He suggests that your department, and the company, adopt a nontraditional database. You recommend against it and explain that

A$.$ nontraditional databases have not yet been completely vetted by industry, and time should be allowed for them to succeed or fail

B$.$ nontraditional products have nothing to offer your company

C$.$ the cost of the conversion would be far beyond the finances of the company

D$.$ with today's features, nontraditional products are very technical and can be used only by those with a deep background in computer science

E$.$ nontraditional databases could be brought in for use in new projects, but that there is no need to make it a company$-$wide adoption
