Chapter 12 : Knowledge management system.
Portal logical architecture
HOW TO STRUCTURE ARCHITECTURAL ELEMENTS NEEDED TO SUPPORT AN ONLINE COMMUNITY
An exciting compelling content experience is about enabling your producers to be able to quickly add, remove and re-gig content, design, navigation, and to be able to do with it with the complete confidence that they are not going to break the portal.
Common features are
- Bespoke hand crafted applications that provide features such as “Pay My Bill” or a view on some data that is specific to your portal.
- Feeds from other sites, systems or legacy equipment
- Identity systems, sometimes called SSO
- Forums allowing visitors to contribute to the site .. and become members
The knowledge management system could as simple as an SVN instance or file share. It could also be as complex as a sharepoint installation.
What brings the whole site together and unlocks your producers creative ability is the CMS. Back in the late 90′s every company had its own CMS. Alot of them are still with us, quite a few have been productised. Whatever happens, dont make your own till you tried the free ones on the market.
As we saw with the environments success is all about the flow of contents and features. This is why it is essential that your knowledge systems are abstracted from your publication systems.
The collection, storage and efficient retrieval of your companies knowledge is very different when compared to presenting a shop front or community portal to the public. Just because you have similar technical requirements it does not mean that both needs should be for filled by the same system.

Chapter 11 : Information system
An information system (IS) - or application landscape - is any combination of information technology and people's activities that support operations, management, and decision making. In a very broad sense, the term information system is frequently used to refer to the interaction between people, processes, data, and technology. In this sense, the term is used to refer not only to the information and communication technology (ICT) an organization uses, but also to the way in which people interact with this technology in support of business processes.
Some make a clear distinction between information systems, computer systems, and business processes. Information systems typically include an ICT component but are not purely concerned with ICT, focusing in instead on the end use of information technology. Information systems are also different from business processes. Information systems help to control the performance of business processes.
Alter argues for an information system as a special type of work system. A work system is a system in which humans and/or machines perform work using resources to produce specific products and/or services for customers. An information system is a work system whose activities are devoted to processing (capturing, transmitting, storing, retrieving, manipulating and displaying) information.
As such, information systems inter-relate with data systems on the one hand and activity systems on the other. An information system is a form ofcommunication system in which data represent and are processed as a form of social memory. An information system can also be considered a semi-formal language which supports human decision making and action.
Example of Information
Starbucks Corporation is an international coffee company and coffeehouse chain based in Seattle, Washington. Starbucks is the largest coffeehouse company in the world, with more than 17,000 stores in 55 countries, including over 12,500 in the United States, over 1,200 in Canada and over 700 in the United Kingdom, 54 in Russia.
Starbucks sells drip brewed coffee, espresso-based hot drinks, other hot and cold drinks, coffee beans, salads, hot and cold sandwiches and panini, pastries, snacks, and items such as mugs and tumblers. Through the Starbucks Entertainment division and Hear Music brand, the company also markets books, music, and film. Many of the company's products are seasonal or specific to the locality of the store. Starbucks-brand ice cream and coffee are also offered at grocery stores.
From Starbucks' founding in later forms in Seattle as a local coffee bean roaster and retailer, the company has expanded rapidly. In the 1990s, Starbucks was opening a new store every workday, a pace that continued into the 2000s. The first store outside the United States or Canada opened in the mid-1990s, and overseas stores now constitute almost one third of Starbucks' stores. The company planned to open a net of 900 new stores outside of the United States in 2009, but has announced 900 store closures in the United States since 2008.

Chapter 10 : The pros and cons of information technology
Information technology has helped the world with the same level. Without his contribution, there is no doubt that we now do not get this "technical world" or. But even if some people raise a number of statements (which may be unfounded) thatthe information technology (IT) are taking away the privacy of ordinary people and breaking international reputation of the world wide human knowledge.
So let some positive aspects in this article (OPR) and poorEffects (v) InformationTechnology in places. According to the definition of a Google service, it is said-
"The branch of engineering that get on the use of computers and telecommunications, and store and transmit information." – Definition of Google.
Therefore, the definition in that it provides, it is clear that this is "the branch of technology that helps us communicate with each other, technology transfer individual knowledge, and our store with your computer and other modernmeansInformation Technology. "
Information Technology Pro
1. The world has the flexibility
we do or what to think, plan employees, colleagues and friends are our shared with.Internet technology, this system has a high degree. The idea of the telephone (Alexander Graham Bell) was changed and made like mobile phones, to increase the flexibility in communication and talk to our dear comrades, wheneverDemand!
2. The sense of responsibility has increased
Let 'Barack Obama President of USA, "as the figure. The use of networking sites (Twitter and Facebook), blogs, social bookmarking, the LEADER approach in the world, if necessary, we can send messages and updates that are ( or will be made by us) will be 'within a very short period of time.
3. Just to think, and developments in the transport sector
Of thought and research, weResources need to find out what people thought of our past, which the quotations that have left us (information theory + +). We can use it with a single click in the search engines (especially Google ™, Yahoo) to find. By a clear cut idea, we have the opportunity to help the world with new ideas and technological inventions and to share what we learned during our lives.
And over the centuries has contributed to a widening of the transport strategy that helps us attend to one place to anotherof (roads, highways, air, water and sky!)
4. This allows you to save thousands of lives every day
Then, from the point of entry I hope you understand me relate to the development of the medical field. Every day people relief with the perfect use of medicine, hospital technology, by adding (X-rays, laser treatments) and more in the queue. With the combination of World Health Organization, several life-threatening diseases to overcome and be expelled from the newly establishedCountries rapidly and the plans and ideas.
5. Increase the sense of human rights
Technology can remember those of our human rights, basic needs and updates made available to or around the world where it is necessary to help alleviate. During earthquakes, floods, horrible, that during the cooperation is necessary on the World Wide Web Help us to collect the donation of a set.
They can not understand, it's about good and bad sides of the Information andTechnology ManagementWithin a page and how, as he mixes with all aspects and angles of our lives. Rather, we have seen in side effects bad side (cons) that led in the sectors of human society.
Information Technology Cons
He pulled the privacy of individuals
As the IT sector the hearts of people around the world have wined. People are here to share and store any kind of information, the date of the individuals in their private hard drives and onlineDatabases. But because of some computer criminals, is not as safe, both online and offline. If someone has a little "sloppy, he / she has to pay high. (E 'heavy).
The online community is not safe for the family more
Children under the age can often share cell numbers, e-mail contact, which can be manipulated by people and pass it to the criminals who harm a blueprint of the company. And people lose their privacy and credit card payments from otherProcessing options. Again, there are several Web sites created perverse that a child can be worn under the age of eighteen in a different place – that the nation is to bring Harms.
E 'intention to harm a human Natural Power
People should be the best of all creations (in Islam). We can imagine, to collect the human principles (ethical knowledge) and then working relationships with friends and family. But because of the harmful aspects of the (IT) People are always fullbased technology. And it can bring great harm to society by taking away the thoughts and ideas of natural organic.
You can bring effective administration without World Destruction
This is something more that I write, having regard to the various science-fiction. Great scholars have, even if the problem with wisdom. Up to now (people) we are holding a prominent place in the world and the management of information technology. But come one day, when theThe technology is for us to manage all aspects. It is possible that we will probably convert the slaves of technology.
So from this I am not trying to say that the technology to bring harm here, just because I have a technological man over 24 hours of navigation computer and talk on the phone itself. But as part of human society, we must take a look at both sides.

Chapter 9
When you're surfing the Web, you probably only think about one thing when you look at a Web site: whether or not it's fun.
Good websites :Evaluating website..
But when you're looking for information on the Web for school -- or really any time that you care that what you find is true and up-to-date -- you have to evaluate the website to make sure that you can trust the information on it.
Here are some questions to ask when you're looking at a website that will help you decide whether or not it's good:
WHO MADE IT?
Anyone can make a Web page. In fact, not only can anyone make a Web page, anyone can make a Web page and lie about who they are! You could make a Web page that said you were Eminem, and no one would stop you from putting it on the Web. But sites that really belong to the people they say they belong to have some things in common:
- There's some way to contact the people responsible for the site; usually an e-mail address, sometimes a phone number and street address, too.
- Pages within the website look similar: they may have the same background color, or there will be the same logo on every page.
- Pages within the website link back to the home page, and to elsewhere in the site.
- The website shows signs of being proofread; there are no spelling or grammar errors.
If you're going to use information from a website for a school project, think about getting it from a website that you already know will have good information, such as the website of a library, a school, or a museum. Often, libraries, schools, and museums will have links on their sites to other sites that they have already evaluated for quality and accuracy. The Multnomah County Library Homework Center (www.multcolib.org/homework/) is a good place to start.
WHEN WAS IT LAST UPDATED?
Look for a 'last updated' date near the top or bottom of the site's home page. If a website has been updated recently, that's generally a good sign. It means someone's paying attention to the site, making sure links still work, maybe changing parts of it to reflect more recent news or research. But it's not always necessary for a website to have been updated recently for it to be valuable. For instance, if a website provides the full text of Shakespeare's sonnets, that text isn't going to change, so it's not necessary for it to be frequently updated.
IS IT CLEAR WHAT IT'S ABOUT?
You should be able to tell why a website exists, and what information it's trying to provide. If the purpose of the website is confusing or unclear, that's a good sign that you should look for a different site.
ARE THERE A LOT OF ADS?
Ads can be long, rectangular banners at the top or bottom of the screen, or sometimes they are on the left or right side of the screen. It's not always easy to recognize all the ads on a page; sometimes ads will look like messages from your computer, or just like part of the website that you're looking at. Teach yourself to spot ads, and be aware that if a website has a lot of ads, you may want to think twice about whether the information on it is unbiased. However, many valuable sites do contain advertising to help support themselves.
IS IT EASY TO FIND THE INFORMATION YOU NEED?
You won't always be able to find exactly what you need right on the very first page of the first website you go to. Looking at different places and gathering information from them is what doing research means. But if it's very hard for you to find the information you need, and especially if it seems that information from one part of the website contradicts another part, you may want to try another site.
SOMETIMES, THERE IS NO GOOD WEB SITE.
If you're having a really hard time finding anything for the topic you're interested in, you may want to look elsewhere: in books, magazines, or newspapers. Also, remember that you can always ask a librarian for help searching for any kind of information you need.

Bias information
Description
When we are trying to make a decision, we generally seek data on which to rationally base the choice. Where this goes wrong, is when we assume that all information is useful, and that 'more is better'.
Sometimes, extra information adds no significant value. Sometimes it simply serves to confuse.
RESEARCH
Baron, Beattie, and Hershey (1988), gave subjects a diagnostic problem involving fictitious symptoms, tests and diseases. Many subjects said they would need additional tests even when they had sufficient data.
EXAMPLE
A manager gets consultants to do a study of the marketplace when a third party report is already available at far less cost.
SO WHAT?
Using it
When you want people to pay attention to your information, even when they have other information you may well be able to present it, for example as 'new findings'.
You can also deliberately create overload by encouraging people to seek more and more data.
Defending
Think first about what information you need and go for that which is just sufficient and necessary.
Examples of Bias : Global warming
- Conservapedia posted the news about liberal corruption of global warming science (climategate) on its Main Page on the very first day: November 19th. But it took Wikipedia over two weeks to give priority to this bombshell, and even now its entry is remarkably biased against it.
- 100's of other climatologists have been removed from the category "Global warming skeptics", which Wikipedia decided to delete.[Wikipedia's most controversial pages are guarded by liberal elite. Thereby, accuracy is replaced with ideology. The first one-hundred and sixty-eight words on Wikipedia's Global Warming page contains multiple conjectures, major errors and bias. "increase in the average measured temperature ... since the mid-twentieth century" that same paragraph "solar variation combined with volcanoes ... and a small cooling effect from 1950 onward." Which is it, warmer or cooler from 1950? "very likely due" "probably had" or "the overwhelming majority of scientists working on climate change agree with the IPCC's main conclusions"- unsubstantiated bias.

Chapter 8 : Search Engines
How do Search Engines work?
The term "search engine" is often used generically to describe both crawler-based search engines and human-powered directories. These two types of search engines gather their listings in radically different ways.
Crawler-Based Search Engines
Crawler-based search engines, such as Google, create their listings automatically. They "crawl" or "spider" the web, then people search through what they have found.
If you change your web pages, crawler-based search engines eventually find these changes, and that can affect how you are listed. Page titles, body copy and other elements all play a role.
Human-Powered Directories
A human-powered directory, such as the Open Directory, depends on humans for its listings. You submit a short description to the directory for your entire site, or editors write one for sites they review. A search looks for matches only in the descriptions submitted.
Changing your web pages has no effect on your listing. Things that are useful for improving a listing with a search engine have nothing to do with improving a listing in a directory. The only exception is that a good site, with good content, might be more likely to get reviewed for free than a poor site.
"Hybrid Search Engines" Or Mixed Results
In the web's early days, it used to be that a search engine either presented crawler-based results or human-powered listings. Today, it extremely common for both types of results to be presented. Usually, a hybrid search engine will favor one type of listings over another. For example, MSN Search is more likely to present human-powered listings from LookSmart. However, it does also present crawler-based results (as provided by Inktomi), especially for more obscure queries5 examples :
