Some "architect" might tell you that "oh, but we handle the real customer uniqueness constraint in our app tier!". If the customer identifier column is now left without a uniqueness-guarantee, you are asking for future trouble throughout the organization because the GUIDs will always be unique. Next, for some reason (which I can't think of), you are asked to add a GUID column to the customer table and make that the primary key. To guarantee no duplicated customer records, you add a uniqueness-constraint to the table, either through a primary key on the customer identifier or via a NOT NULL + UNIQUE constraint on the customer identifier column. So you have a customer identifier which uniquely identifies the customer and you make sure that the identifier is known by the customer (in invoices), so that the customer and the customer service people have a common reference in case they need to communicate. Surely you don't want a customer to exist in the table more than once, or lots of confusion will happen throughout your sales and logistics departments (especially if the multiple rows about the customer contain different information). So if you need insert performance, maybe use a auto-inc INT, and generate a GUID if you want to share it with someone else (e.g., showing it to a user in a Sheppard: If you have a lot of records, and a clustered index on a GUID, your insert performance will SUCK, as you get inserts in random places in the list of items (that's the point), not at the end (which is quick). So this one gets +1'ed a lot, and I thought I should point out a big downside of GUID PK's: Clustered Indexes. the title - make it the-title-of-the-article) public ID is generated ONCE from some field (e.g.unique ID for the row (GUID/whatever).We DO use the WordPress-like system though: Surrogate keys are usually frowned upon where ever I've been working. I think the duplicate data thing is rubbish - you can get duplicate data however you do it. Personally, I use them for most PK's in any system of a decent size, but I got "trained" on a system which was replicated all over the place, so we HAD to have them. Harder to do manual debugging, but not that hard.Can look ugly in a URL, but really, WTF are you doing putting a REAL DB key in a URL!? (This point disputed in comments below).Can't order by ID to get the insert order.Larger space use, but space is cheap(er).So We can use the PK's from our CMS (guid) in our app (also guid) and know we are NEVER going to get a clash. Makes replication trivial (as opposed to int's, which makes it REALLY hard).Its Professional edition supports Windows Vista, 7, 8, 10, and Windows 11 while the Enterprise edition also supports Windows Server 2008, 20.
