Question

For the Cities database, discuss one problem with either the correctness of the data or what can be easily done with the data that might occur if each of the following changes were made

: • The state attribute of the City table was allowed to be null

• The County table was merged into the State table by removing the County table and including a counties column in the State table with the names of the counties, plus a websites column in the State table with the websites for each county. The county column of the City table would just be the name of the county.
