Default What's an internal id?

Two questions. Well, maybe a couple more.

First, what is an internal id? What's it used for? Is it a bad idea to tell people what my wiki id number is? (I'll keep my id number secret until I have some solid infomation)

Hi jasong,

I think I may respond to this. My wiki id is 363199.

It is a so called Primary key. This is used to identify information as unique.
E.g. "CedricVonck" is not unique.

Id Name
1 CedricVonck
2 CeDricVoNCk

The number or Id is a "sequence number" (Oracle database)
It is also used when you are linking tables together (constraints)
Code:
Entity book                      Entity BookUsers            Entity Users
1  Oracle programming       1 (bookid)      1 (userid)  1 Cedric Vonck
2  Sql                      2               1             2 xxx
3   Excel                   2              2
This examples says book 1 is read/bought by user 1
Book 2 is read used by user 1 & 2

See:
http://en.wikipedia.org/wiki/Database_normalization
http://www.oracle.com
http://microsoft.com/sqlserver

Hope this clarifies things
Cedric

Is that your id for the Mersenne wiki? Because my id is 97. I thought that meant there were 96 other people who could edit the wiki. Now I'm not sure.

No it is my id for Wikipedia.
The id means not that they are 95 people (some admins, deleted users, etc...)
