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.
What to Think about While Choosing a Writing Desk (writing desk) Writing desks come in many shapes and forms. The technical definition is a piece of furniture with a surface for writing, with drawers and pigeonholes for writing materials and a portable case that when opened forms a surface on which to write. A writing desk could be as complex as that definition or as simple as a desk for writing. Basically a writing desk can be anything that you want it to be. You may not need to buy a writing desk. You may be perfectly comfortable with one you already have or working on the couch or at the kitchen table. This is fine. If it is a cohesive work environment for you that is fabulous, but some writers require a more formal, dedicated area just for them. By finding the perfect writing desk, you are on the way to the start of creative that work style atmosphere that they need. Before you begin your writing desk shopping venture you must first have two things picked out. The area in which your desk is going to go and the chair you are going to use. The location of the desk is important because it will be necessary to choose a size and style. The chair is important for comfort and maybe an important factor in determine the correct height of desk needed. Once these are figured out you shopping journey is ready to begin. While shopping for a writing desk the most important feature is comfort. You need to sit at the desk for most likely for hours at a time. Having a desk at the right height is imperative to this. With the writing surface being to high or to low will not only be uncomfortable but also will more that likely make it difficult for you to concentrate and write. Having a writing desk that is not the correct height is likely to cause neck and back strain. The function and the size of your writing desk are the next factors you need to consider before you purchase one. Do you need one with a little storage or a lot? Does it need to have an adjustable surface or can it just be flat? With all the choices available assessing what you need can help narrow down the ones that will work for you. How big of a space do you have for it? These are some simple considerations that are often forgotten while buying a writing desk. It would be terrible to fall in love with a desk and bring it home just to find out that it is not going to fit. The next important thing is style. When choosing the style of the writing desk you will want it to flow with the furniture already in your home. If your home is modern or contemporary you may want to choose one of the metal and glass desk designs or perhaps one with light wood tones and metal accents are right for you. Another great writing desk available is called the secretary. The secretary is wooden desk with drawers on the bottom and a fold down writing surface. They are usually compact in size but have ample storage and often offer shelving covered by glass doors on top. Plus having a fold down writing surface, it is easy to close up when you are done and hide you space altogether. Choosing the writing desk that is right for you may not seem that important. I mean how difficult could it be to choose a surface to write on, right? But making sure comfort, storage, and style fit into your lifestyle is an important decision. This is part of creating a suitable working environment for you to produce your work. 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. |
