News Blog for 09/29

I learned a lot about databases in this class. I always hear database this, database that but never really knew what it exactly represented. Before the class, I looked on the web and was reading about databases and I found a diagram which was quite helpful. I tried upload it but there's an error in uploading pictures right now so please see website: http://www.techweb.com/encyclopedia/defineterm.jhtml?term=database&x=&y=

However I learned more in depth in class how the relational database works. The diagram doesn’t describe the primary key,etc. Oracle is another thing that I always hear but still not very familiar with however it’s good to know that it is closest to the 12 rules which means that it should be better than others. In class we were talking about the difference between Google and Yahoo search engines so I looked that up a bit.

I found out that in April 2007 Google released a new programming code to enhance MySQL databases. Google uses the MySQL open source relational database internally for some applications that aren’t search related. We discussed the relational database in class and said that with integrity constraints it is more accurate and reliable. Google is one of the largest databases, and includes PDF, DOC, PS, and many other file types. Since Google’s web database is so big, many researchers have provided reports on the size of these components of its Web database to actual search results and what searchers can expect to find. I tried posting charts but it isn’t working but there are many charts from a company press release about the breakdown of the company’s information.
