Muddiest Point for Sept. 16

While it is useful to learn about meta-data, is meta-data useful for database creation?

What are current examples of databases that use the hierarchical and network models?

Reading Notes for Week 4, Sept. 16

As we get into the meatier part of information technology, I feel like posting more muddiest points for the class, this is party because I am more of a visual and hands-on learner, a diagram of meta-data would be helpful (hint).

The Database article was not a difficult article to comprehend. As individuals and students we encounter some sort of database everyday. In the past, I used Excel to organize the conference registration record of 1000 participants. The three types of databases include the hierarchical, network, and relational models. I am most familiar with the relational model. The organization I worked for created a student tracking database related to this model of columns and rows. The database contained over 10,000 student records, linked to the external web-site, and produced reports. An interesting difference between databases and metadata is that databases rely on software to organize the storage of data.

Meta-data is more than data about data. It is the set of industry standards used to describe the “information object.” Not surprising, library professionals used meta-data first to create intellectual and physical access to objects. It has increased accessibility and preserved the integrity of the information objects.

Muddiest Point for Sept. 9

I'm confused about the windows roadmap article. I understand that Microsoft is making improvements to Vista and it will be re-released. When it mentions Windows 7, I got lost. Is Windows 7 an application that belongs in Vista or is it a new operating system?
