If you don't mind, could you post a comment on this entry just so I know that you can see my blog. I just realized that it says I don't have any followers and I want to be sure that you are actually seeing my entries. I'd hate to find out that I hadn't gotten credit for something because the link to my blog was broken for some reason. Thanks!

Week 4

A database is an organized collection of data. There must be a certain degree of quality to that organization for something to be considered a database. Databases use a variety of DBMS's(Database Management Systems). The term 'database' refers to the data and data structures themselves while the software managing those structures is what is referred to as the DBMS. The most standard database language is SQL.

The first databases were navigational models. That means that they accessed data by 'following pointers from one record to another'. Today's databases are predominantly of the relational model which focuses on searchability. 

Muddiest Point: I do not understand what an 'entity relationship model' and a 'query' language are. I also don't feel like I really understood what the navigational model was. I feel like it is likely that next week's lecture will clarify most of this. I've used MS Excel a little before but I do not have much experience working with database management programs which is probably why I'm not as familiar with some of what this week's reading was trying to explain.

Week 3

1. Data Compression.
      Encoding information using fewer bits than the original representation would use.

• Helps conserve hard disc space and bandwidth.
• Lossless Data Compression uses statistical redundancy to preserve data without error.
• Lossy Data Compression is used when some data loss is acceptable(jpeg images among other things).

2. Youtube and Libraries.

• Youtube has many potential applications for distance learning and communicating with patrons in general.
• Possible uses include instructional videos that would let users know where and how to locate and use the library's resources.
• It could also be used to inform patrons of changes to the collection and newly acquired items.
• By subscribing to the Library Channel's RSS feed, it would be easy for users to see any new updates as they are released.
• The maximum file size that can be uploaded is 100 megabytes and the maximum video length is 10 minutes.

3. Imaging Pittsburgh

• The article on First Monday detailed a project to allow access to images from the University of Pittsburgh, the Carnegie Museum of Art, and the Historical Society of Western Pennsylvania.
• There should be up to 10,000 images available by the end of the project.
• Having these images digitized and available from one website will allow greater ease of access and will simplify the task of searching through these collections.

Muddiest Point: I felt like the readings this week were pretty straight forward and I do not really have any questions about them at this point. I did notice as I reviewed my notes from last week that I had written down the term "solid state hard drive" but did not have any further definition. I suppose if I had to list one thing that I would not mind some clarification on, it would be that.
