Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE exhibition ( Exhibition_ID int, Year int, Theme text, Artist_ID int, Ticket_Price real )
TABLE: CREATE TABLE artist ( Artist_ID int, Name text, Country text, Year_Join int, Age int )
TABLE: CREATE TABLE exhibition_record ( Exhibition_ID int, Date text, Attendance int )

### Question ###
What are the names and ages of artists? Show the result in a bar graph, and I want to rank names in descending order.

### Accurate SQL ###

SELECT Name, Age FROM artist ORDER BY Name DESC
