Database
It's interesting how much a DBMS does (development/interrogation/maintenance/development). I don't usually think of a database doing anything, aside from sitting there and holding the information. There are also a lot more types of databases and models than I realized. There are also a lot of safeguards in place, both for security purposes and to prevent computer troubles. One doesn't tend to realize that databases have the potential to cause these things - again, I typically thought of a database just being there. Judging from this, though, there are a lot of little things that they do that never occured to me.
Metadata
This is a term I'd heard before, but I never really gave it thought. I think what made it click is the mention of dates on websites, to know when the information is from - in a computer class I took, one of our assignments was to judge how reliable some websites were, and it being up-to-date was a criteria. I can see how it applies to libraries, though, as adding metadata to something makes it easier to categorize, and thus easier to access.
Dublin Core Data Model
The main thing I got out of this, basically, is that it combines the other two articles for the week. That is, they're trying to make a database of metadata.

I agree on databases, who knew there is that much information stored across such a wide variety of databases. I just really was not a fan of the wikipedia page and how densely it was filled in. I assume database is not a very hot topic on wikipedia so the page is not looked at often, but the database on database is not very user friendly.
ReplyDeleteI am impressed by the fact you managed to get that much out of the Dublin Core article since I got nothing out of it.
ReplyDeleteI also agree on your comments on databases. They strike me as much more useful and important and well-used than I would have ever thought.
