Article 1: Database. http://en.wikipedia.org/wiki/Database
A database is a collection of records and data. The software used is the database management system.
Databases started out using punch cards and data tape. I find this amusing, it must have been a tedious process!
Different databased models are used, some include:
Hierarchical Model, data is organized into an inverted tree-like structure, implying a multiple downward link in each node to describe the nesting, and a sort field to keep the records in a particular order in each same-level list. Keeps a hierarchy of information with logical relationships.
Network Model, can have any number of named relationships
Relational Model, most commonly used, a table where information about a particular entity is represented in columns and rows.
Article 2: Anne J. Gilliland. Introduction to Metadata, pathways to Digital Information: 1: Setting the Stage http://www.getty.edu/research/conducting_research/standards/intrometadata/setting.html
Metadata is data about data. It is any object that can be manipulated.
Metadata has 3 features:
*Content-what the object is about (intrinsic)
*Context-who, what, where, when, how (extrinsic)
*Stucture-formal set of associations within or among individual information objects (intrinsic or extrinsic)
Article 3: Eric J. Miller. An Overview of the Dublin Core Data Model http://dublincore.org/1999/06/06-overview/
My guess on this article is that the Dublin Core Metadata Initiative (DCMI) is trying to find a way to store and recover all the metadata created. Possibly to find a way to combine all links to the information?

Week 3 Readings/Notes
Machtelt Garrels. "Introduction to Linux: A Hands on Guide"
Linux is an operating system that is ideal for programmers, not myself, which is why I have never heard of it. Seems to be a stable and reliable platform used by the postal service and for movies like Titanic and Shrek.
Articles on Mac OS X
Another operating system used by Apple. It said it was a UNIX based operating system, which is what Linux started out as or is based from. I used a Mac at the school I subbed at and I thought I was using Microsoft applications. Obviously I am not computer smart on operating systems other then Windows, which leads to the final article.
Paul Thurott "An Update on the Windows Roadmap"
I can't keep up with technology, especailly on these operating systems. I use Windows and always have, I think it works great and have no other experience with anything else. It getting better with video and audio does not affect me, but I guess for this class I might be wrong. I am glad the security is better. Now they are working on Windows 7, what else can they add?
All in all...
These articles were almost like reading a foreign language. Accolades to those of you who understand hardware and operating systems!

Week 2 Readings/Notes
Computer Hardware
I was already aware of the difference between hardware and software and that software can change many times, whereas your hardware stays the same. It was a good refresher though. I am assuming that this will be the topic of discussion for Tuesday class.
Moore's Law
I found it absolutely fascinating what people knew about computers in the 60's. Although Moore's Law was a prediction about hardware, it was right. I am glad we were able to watch the video for dummies, because it helped me understand what I was reading. To think, the more something improved, the less money it became, is a hard to grasp. I am wondering why?
Computer History Museum
This was a really interesting website. I was looking through the history of the internet, which I watched a video on in a web design class in my prior master's, and I thought it was cool that Pitt/Carnegie Mellon was part of the process.

Week 1 Readings/Notes
OCLC report: Information Format Trends: Content, Not Containers (2004).
This article opened my eyes to all the new technology that can be used in the library that would gain student interest. I, myself, have never blogged until now, so this is all new to me. Blogs and Wiki's would be a good way to use technology in the library. For instance, a book club.
E-books are also something that I think will become big. This is another good way to get kids involved in reading.
Clifford Lynch, "Information Literacy and Information Technology Literacy: New Components in the Curriculum for a Digital Culture"
This article helped me decipher between Information Technology Literacy and Information Literacy. As stated, "Information Literacy deals with content and communication", where as "Information Technology Literacy deals with an understanding of the technology infrastructure".
I agree with the author about students needing to learn both information literacy and information technology literacy in school even if they are not going to college. As the world becomes more technologically advanced, so should all its inhabinants, which starts in k-12 schooling.
