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.

I learned a lot from the presentation on Monday. The Dragon Naturally Speaking 9 program seems very interesting. But I had second thoughts about it because it’s a voice recognition program and there are many different accents out there, so would it really be 99% accurate? This doubt was confirmed by the girl who raised her hand in class that had the previous version of the program; I think these programs still need to be worked on cause basically the computer needs to take time to learn the persons accent before being able to accurately type while the person speaks. Another thing that I found useful was the Google Docs/Spreadsheet. I think I might be using that to do projects from now on. It seems pretty easy to use and great for group work. I really have been learning a lot in class cause previously I didn’t know what DOS and LINUX was. I have heard of them but never really looked into it until this class.
Computer networks are very useful however I read in an article that 58% of businesses expect an IT security breach in the next 12 months in London and Surrey regions. This actually might happen in America also. I know that my previous company was creating a disaster recovery plan. These are crucial factors for all businesses. Since networks are so broad now and easily accessible, we need to have precautions with security, viruses, and spam threats. But actually in this article London was talking about Blackberry devices and I think that they are slower in technology than America. In the US, I know many companies have been using Blackberries to communicate. I feel that it’s a very convenient way to communicate especially when not in the office.

The presentation in class was quite interesting. I learned a lot of new things. The digital book does sort of interest me however I don’t know if I would buy one because reading off of a computer screen for a long time already irritates my eyes. The digital book would be even smaller so I’m not sure if I can read the whole book with it.
Another thing that fascinated me in class was the lecture about magnetic fields of brain controlling a computer. It sounds very interesting however in the end I think it proved the point that it’s the human who has to adjust and teach the computer cause the computer doesn’t think for itself and may not be able to communicate the brain waves correctly.
My computer seems to be acting up lately and I think there may be a virus so I was looking at websites on how to fix it. I came upon an article about multiple antivirus applications on one pc. It suggest that running multiple security applications can wreak havoc on Windows and crash the computer. Basically I learned and want to let you guys know that you cannot use more than one antivirus and firewall on the computer; however it is okay to have more than one anti-spyware installed in the computer.

Individual Assignment Blog for 09/15
What is a computerized physician order entry (CPOE) system?
CPOE is a process of electronic entry of physician instructions for the treatment of patients under his or her care.
What are its basic functions?
CPOE are for easier communication of patients under a physician because CPOEs are communicated over a computer network to the medical staff or to the deparments responsible for fulfilling the order. It basically decreases delay in order completion and may reduce errors related to handwriting or transcription.
How many hospitals in the US are using such a system?
As of 2004, there were surveys done and found that 16% if US clinics, hospitals, and medical practices are expected to use CPOE within the 2 years.
Recent literature cites that between 5% and 9% of U.S. hospitals currently have CPOE
systems in place. Of the thousand hospitals responding to the most recent Leapfrog
hospital survey, only 4% had fully implemented CPOE systems; another 16% planned
for implementation by 2006.
What are some benefits and some disadvantages?
Benefits:
- decreases delay in order completion
- reduces errors related to handwriting or transcription
- allows order entry at point of care of off site
- provides error checking for duplicate or incorrect doses or test
- simplifies inventory and posting of charges
- saves money
- enhancing patient safety
Disadvantages:
- systems take years to install and configure
- computer errors
- at first, the prescribers/staff who are inexperienced at using the system may cause slower entries instead of faster entries
- in an emergency situation, the computer will be slower than a person to person communication
- cost of training (everyone needs appropriate training)
- technical issues with and balances to ensure that the system is used as intended and that safety checks are not circumvented
- overrides caused by automatic systems
What do you think are the main obstacles that prevent computer systems from improving the medical industry?
Doctors may be resistant to changes in their own practice patterns and computer systems are very costly. To many clinicians, CPOE requires more steps, more interaction and more drug product ordering information, which they consider an undue burden.
Also I think many people are still skeptical towards computer systems. What if there was a crash in the systems, then are the information will be lost. I work for Healthfirst and all our documents are scanned and stored on the computer however we still keep paper copies in the drawers as backup.
Sites I used to answer questions:

News Blog for 09/08
The dell website was interesting. I never shopped on the dell website so when I saw it in class, I went home and started looking into it. It really gives thorough information about each part of a computer and what are the better components. This is a very helpful website and I think I will probably use it when I’m going to get a new computer. Another thing I learned in class was Mozilla. I have never heard of that communication software before. Actually I think I saw my coworker using firefox before, but I just didn’t know hat it was.
In an article on the web, I was reading about the “Computer-on-a Stick”. The website is: http://hardware.earthweb.com/systems/article.php/11060_3526676_1
Many people now use USB flash drives for saving their work because it’s convenient to carry. Now think about being able to carry your computer (your operating system, not just applications) around. FingerGear has just created “a bootable flash drive that carries a modified Debian Linus 2.6 OS and Gnome 2.8 desktop along with the Microsoft office-compatible openoffice.org suite, firefox browser, GAIM instant messaging client, and other programs” (article page 1). The idea is definitely great and I think it would be really convenient if I could own a portable computer the size of a pack of gum. However there are still some flaws to this new creation. The stick only has 56MB for data because of the space the OS and other applications take. The security is too tight because the password cannot be changed once set. Lastly, it is difficult to add and upgrade installed software; as per this article, it is the fault of Linux which is far from plug and play on every PC. This article is quite interesting for most people who like convenience and computer gadgets. Personally if they do successfully create this mini hardware, I would get one for work and school.
