Using enumeration in Java as an alternative to a small database

Question

I have a Java application that uses the Country class. Business logic connects every country in the world:

• Iso code.
• Telephone Phone Code
• A list of TZ database time zone identifiers suitable for this country.

Usually this data is ideal for a database. However, given the fact that this data is quite stable (of course, it changes from time to time, but it is usually not used to create / update / delete operations in these records). I was thinking about putting information into a list, like this:

public enum Country
{

   US(1,new String[]{"America\New York","America\California",...}),

   ...

   NL(31, new String[]{"Europe\Amsterdam"});

    ...

    public Country(int telephoneCode, String[] timezoneIds)
    {
       ...
    }
}

Possible benefits of this approach:

• Data is directly accessible from Java source code, so there is no delay when querying the database.
