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.
The Definition of Writing Styles Depends on Who is Defining Them (writing styles) While researching this topic, you may have found many different answers to what are the different types of writing styles. No two answers were the same. They range anywhere from your personal way of writing that is your writing style to formal and informal. Many people feel the best answer to what writing styles are the those will be outlined below in this article. You can decide for yourself if this definition suits your. The term creative writing covers a range of writing areas. Poetry, fiction books, short stories, and screenplays are considered creative writings. Any writing in which is not strictly non-fiction would be classified as such. Journalism and news reporting are forms of Expository writing. The purpose is to focus on one topic and inform the reader by provided the facts. These writings can be seen in the forms of travel brochures, professional journal, business reports, and new paper articles. Descriptive writing is what gives you the mental pictures of what we have read. It uses a lot of adjective and adverbs to describe things. When descriptive writing is very good you can close your eyes and know exactly what the author is saying. The kind that makes you taste what the characters and see what they are seeing. Analytical Writing is a writing that focuses on a topic and then verifies the purpose of it. It is often taught school age children through out the years because it is something they will use in their life. Book reports, conference papers, thesis, essays, and dissertations are all academic writing. It is created using a third person point of view and deductive reasoning supported by facts. Its purpose is to show a clear understanding of a subject by presenting information. Technical Writing is used in owner manuals, how to guides, magazine articles, and design specs just to name a few. Its purpose is to take complicated technical information and turn it into something the intended audience can understand.

Business writing and technical writings are often one in the same as are academic writing and analytical writing. With the overlapping of the styles it hard to define one writing style from another, you can guess it is all a matter of the point of view you are looking at it from and your opinion. News is News All Over the World (writing newspaper articles) Writing newspaper articles is a fun and interesting line of work. Newspapers exist in big cities, small towns, within corporations and on college campuses. Newspapers are printed for special interest groups as well as for world and national news. There are free newspapers and papers that appear for sale on newsstands every day. With such a large variety of newspaper types printed, there are myriads of possible opportunities for writing newspaper articles. There are some basic rules to writing articles for any newspaper and there are also some specific aspects to know about each type. Writing Newspaper Articles In general, to write a newspaper article there are a few rules that apply across the board. First, the news has to be relevant. Because newspapers make up a genre of writing that is constantly refreshing itself, there is no room for common knowledge or historical pieces. The exception is if those kinds of writing serve to connect to a current issue or event. People who read newspapers want to know what’s happening now. For that reason, writing newspaper articles often involves relatively high pressure to get the latest news written each and every day. There are some low-pressure possibilities in writing newspaper articles though. The Infrequent Print Several newspapers are only printed weekly or even monthly. In small towns that must get their papers printed off-site, it is not feasible to create a paper each and every day. That means that there’s a week, every week, to get the news in and written. Another example of low pressure writing for newspapers is working for a free publication. Free newspapers are often geared to a special interest group. Since that group is not paying for its paper, they may only receive the interesting tidbits once a month. Writing for these kinds of newspapers becomes focused on creativity and niche writing because the current events will have already reached the audience through more frequent publications. The Daily News from Top to Bottom The most reliable and frequent publications are those of big, national newspapers. The staffs are very large and are able to print very clean copies of very full newspapers. By clean, that means without errors. Smaller papers are also printed daily, but they seem almost insignificant except to the people of the local community. They receive national news second hand and run very small staffs. Interestingly enough, none of these daily papers are really about the news. Of course that is where most of the effort lies and that is the reason that people buy the papers, but it is not the root of a newspaper. Writing newspaper articles is a job heavily dependent on the advertising industry. A newspaper will only be as large as there are ads to pay for it. Newspapers do not make their money at the newsstand. They pay the bills and the employees with money from advertisers. On Campus News Working for a university paper will not be representative in the area of newspaper advertising. While some businesses do pay for ads in university papers, the funding comes from the school. If for some reason there were no advertisers one day, the paper would still go out. University publications are much more focused on the development of the students than making a successful business. Most campus papers are free and are created by students. School is a great place to get started in writing newspaper articles. The environment is challenging, but nurturing at the same time. The deadlines and standards still exist, but the writer gets great encouragement and training through the work. After working for a college paper, it will be much easier to get a job with newspapers of the cities and towns. Writing newspaper articles can be a great job. There are so many opportunities to get into writing that it is hard to pass them up. Some jobs may be very difficult to get, but others will be steps towards increasing writing success. |
