Web Hosting - Databases, What Are They and Do You Need One?
'Database' is one of the most commonly used terms that one encounters in web site design. Yet, what they really are and whether they're essential is often not clear to novices.
A database is a collection of organized data, stored in files that have a specific structure. It's that organization and structure that allows for easy and rapid storage and retrieval.
The need for a database generally only arises when you have a certain amount of information and that information needs to have some structure. If you have a half-dozen names and addresses to store, a database is usually overkill. If you have a blob of data with no relationships between any of the items in that blob, maintaining a database is usually more trouble than it's worth.
Maintain a database? Yes, like other complex systems a database, to be effective, needs to be designed properly at the outset then kept 'tuned' for good performance. The alternative is to gradually allow the database to become more and more disorganized. That leads to difficulty in use, poor speed of retrieval and more frequent failures.
With MySQL, Access or MS SQL Server, the three most common choices of database product for web sites today, setting up a database is relatively simple. Even those with limited technical skill can get one up and running just by following some simple instructions. But some thought should be given to how you want the information organized, and to maintaining the system during its lifetime.
Suppose you have a set of names, addresses, email addresses, products purchased, date purchased and amount. If you have only a few dozen records it matters very little how these pieces are arranged and related. A database usually isn't even warranted in this scenario. Once you have several thousand or more records, it matters a lot. Speed, the ease of expanding the set of attributes (like adding, say, product category), and other issues come into play.
Even those with little technical expertise, but a willingness to exert logical thought and invest some time, can build a very robust database. Think about how you would organize a set of data (called 'tables'). Should Name, Address, and Product be in the same table? Or should the personal information be stored in one table and any product information (product, price, ...) in another?
Some experimentation may be needed to get it right, but the choices have an impact on how easy the tables are to maintain. It also affects the speed with which programs can fetch old data and store the new.
Having a database also introduces new maintenance issues for the server administrator, since backups usually need to be done differently. Recovering a failed database is usually more complicated than simply re-copying files from yesterday. Ask your hosting company what tools and skills they have for dealing with any database system you consider.
It's true that introducing a database creates more complexity and the need for additional thought and administrative effort. At a certain level, professional expertise will be needed. But clearly the advantages outweigh the costs in many cases. Companies large and small eventually use databases to store and organize data. At some point, you may be fortunate enough to be one of them.
Copyright Law Plagiarism Plagiarism Is Simply Unethical Anyone who is a writer is concerned with plagiarism. Copyright Plagiarism Laws protects copyright holders from having their works plagiarized. Many people think it is ironic that the word plagiarism derives from ?kidnapper? in Latin. However, it is true. If a person uses another person?s words without permission, they have indeed stolen or kidnapped something that was owned by another and is in violation of copyright law. Plagiarism is a very bad word in the writing world. Crediting the author of the work will not keep someone immune from being in violation of copyright law. Plagiarism is plagiarism, even if the author is cited if the author did not give permission for the work to be used. One of the most common areas that copyright law plagiarism is violated is in the academic world. Many students will copy and paste the information they need for their research papers and essays straight off the Internet and turn it in to their professors. However, this type of cheating is easily detected now with special programs that professors can use. Plagiarism is unethical, not only in the writing world, but in the academic world, as well. Did you know that you could plagiarism a work but not be in violation of the copyright? Likewise, you can be in violation of a copyright and not have been plagiarizing. It is really not that hard to understand. Let?s say you are using Abraham Lincoln?s exact words in a paper and you did not cite him as the source or give him credit. Well, Lincoln?s words aren?t copyrighted because they are in the public domain. But, you did plagiarize because you tried to pass off his words as your own. Alternatively, if you use a picture in a book and you did not gain permission to use the book, you have violated copyright law because you did not source the artist and you did not get permission from the artist to use the picture. If you are in school, the best way you can get around committing plagiarism is to simply list your sources. If you use someone?s word, list it in an endnote or in a footnote. List the resource you found it in the bibliography. Another way around copyright law plagiarism violations is to take notes when you are reading. Take notes in your own words and put the resource away. Write your paper from your own words. No one wants to be singled out for plagiarism, especially a student who is concerned about their reputation at school and writers who need to keep their credibility in good standing. With today?s technological advances, it is not too hard to pinpoint plagiarized work. Even webmasters who run websites are on to the plagiarism crowd. They can run their entire sites through a special program to see if their content has been stolen and duplicated elsewhere on the Internet. If you are dealing in the written word, either academically or as a profession, it is a good idea that you only use your own words. It was probably easier to get away with plagiarism 100 years ago, but it is not that easy today. The changes are very high that if you are caught violating copyright law plagiarism laws you will be caught. Not only is it embarrassing, but it can cost you a bundle in a lawsuit. Non copyright music downloads Non Copyright Music Downloads Offer Growing Options for Music Collections Non copyright music downloads are growing in popularity and providing much needed exposure to many 'starving artists'. The truth of the matter is that many artists are turning to open source applications or creative commons licensing which allows them to provide their music to others while still retaining their ownership. It's a great idea that has actually worked quite well within the software community and is just now taking hold within the music industry. The idea of services such as this that offer non copyright music downloads to consumers for their listening pleasure is a relatively new concept that is beginning to take hold throughout the online music community. It is important to remember that while there are a few names that are recognizable and reputable in this particular industry there are also those that have less scruples than others and are more than willing to take advantage of music lovers for the fees they will pay and/or a credit card number and personal information. It is always wise to be aware of the information you are sharing online and to take great pains not to give information to companies that aren't absolutely secure and reputable. There are so many 'back room' websites that offer you unlimited music downloads for a yearly or lifetime subscription fee that sounds to good to be true. The problem is that many of these have a very limited selection of non copyright music downloads or quality music and only offer substandard and non mainstream music that no one has ever heard of or they offer music sharing that is not at all legal and puts you in a precarious legal position. The law holds you accountable for what you do rather than what you understand you are doing more often than not. Thinking you have non copyright music downloads is not the same as actually having them. So don't believe everything you see when it comes to defining legal and illegal music downloads. Find companies that have good reputations and don't go with cheaper services that are suspect and vague in their description of services. Non copyright music downloads or open source music is still relatively new. There are a lot of questions that leave a lot of room for misunderstandings, confusion, and consumers being taken advantage of. Educate yourself before subscribing to any of these services. Check out several do searches online to see if there is any negative feedback about these companies, read the feedback and see what people have to say. You can't believe all the negative you read but if many people complain about selection or quality it's quite likely that they don't have a good selection or great quality. Know what you want and find a service that will give it to you in non copyright music downloads. Another thing to know about non copyright music downloads is that many of these services are not offered free. There are expenses involved for the company, the hosting, website advertising, the fees they pay the artist, and any other number of fees-also keep in mind that this is a very time consuming business for them and they have overhead costs in addition to wanting to get paid as well. Remember this is a business for them. You should not expect less of open source music than you expect from other music that you pay a subscription in order to download. Non copyright music downloads are definitely the wave of the future and the technology had better be able to keep up with the demands of consumers. |
