Database desigining confusion {please help}

[slice]

It doesn't matter how many people have visited how many countries.. the "PersonCountry" table will store all combinations, using one row per visit. If you want to add a country to the list of where a person has visited, simply add a new row; if you want to remove a country, simlpy delete the row.

The table would contain data like this (a re-arranged version of the data you posted above):

PersonCountry 
PersonID  CountryID
3            1
3            2
3            3

To find all of the countries that a person has visited, you would use an SQL statement like this:

SELECT Country.Name 
FROM Country
INNER JOIN PersonCountry ON (PersonCountry.CountryID = Country.ID)
WHERE PersonCountry.PersonID = 3

(replace 3 with the ID of the person)

I understand it totally and its fine but wouldn;t it create heavy database and too many records ?
for 100 persons with 50 visits in this i have to create 5000 records while in {1,2,3...} method it would require only 100 records?

please enlighten me little more about this issue
