Hi, I have some questions about using unique ID's in my database.
1. Is it better to use ID's or for example Names or email as primary key.
2. What are the disadvantages of using ID's as primary key in the tables in my database?
3. Would it be more easier to make queries with ID?
4. Does this make joins statements more difficult?
5. Would ID's make a webbased program work slower?
Thanks in advance,
Gaylord
