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.
A Writer’s Best Friend: The Job of an Editor (editing) Are you irritated by typos and spelling errors in professional documents? Are you able to help your friends make their writing error free? You may be a good candidate for editing. The world is incredibly dependent on writers and the craft of writing. It is how people communicate with each other most often. As the internet writing forms do not require people to hold to correct grammar, spelling or professional style, most writers are losing their capabilities to complete a professional document or book without help. Writers have always needed the help of editors. Even when there was strict attention to correct writing, editors could come and catch missed errors as well as mistakes in content. Editors are still needed today. Read on to find out more about what can be involved in a life of editing. Who are the Editors? Editors are those people with the ability to read a document and guide a writer to make it the best piece of writing that it can be. Editors work in newspapers, and magazines. They also work for publishing companies and in student resource centers. Editors generally have some education that leads them to the ability to help writers. They probably have a degree in language as well as training with style manuals. What is the Job? An editing job involves taking a piece of writing and conforming it to some particular set of standards. Style manuals are often the standard used. Different publications will choose a style and then ask the editors to make all of the writing that comes out to be consistent to that style. Editing is not only concerned with objective corrections like spelling and grammar though. An editor must also read for clarity, consistency and voice. If a writer claims one thing in one point of their piece and seems to contradict that point in another part, it is the editor’s job to catch the mistake and work with the writer to fix the inconsistency. If the writer is speaking authoritatively in the beginning of a piece and then becomes apologetic later, it is the editor’s job to make the tone match. Editors help with sentence construction, word choice and content order. How to Find Editing Jobs If any of the above job description sounds interesting and even exciting to you, you just may have found your ideal job calling. Before you start looking for editing jobs, you should test your skills. There are editing tests online. Feel free to use a style manual as well as your intuition as you correct the sentences and word choice in the different test questions. If you do not pass the test, you should probably spend a little more time reading a style manual and a basic grammar guide. Once you can ace an editing test, it’s time to look for a job. Be sure to include any experience you may have had. Include any editing of any kind you have ever done. Peer editing in school is appropriate experience to mention. Also be sure to list any style you are able to edit to. Examples are AP, Chicago, MLA, and so on. If you get an interview, be prepared to take another editing test, with the help of your manual. The test will likely be timed. Editing is a rewarding career. It involves helping writers to do their very best writing geared to their particular audience. While it can be stressful because of deadlines and workload, at the end of the day you will know that you have made the world of the written word a little cleaner and much more effective. Editors are an essential part of making the written word what it is today. Yes, There Really is a Freebie Santa Claus If you are a cynic when it comes to offers of free stuff, you are not alone. Everyone has had notions like “there is no such thing as a free lunch” and “if it sounds too good to be true then it probably is” drilled into their heads, and for good reason – these things often hold water. On the flip side, there ARE actually lots of places you can score some decent free stuff, if you know where to look and are willing to devote some time to hunting them down. The key to getting the best free stuff with the least amount of hassle is to stick with that healthy cynicism but to also dipping your toe in the freebie pool little by little. But why would anyone give stuff away for free? It is certainly an obvious question, but if you stop to consider it for a moment, you can see that companies actually have a lot of motivation to give away free stuff. After all, if they give you something for free, you are bound to have a little soft spot for their company, and when you are ready to part with some cash, their product may near the top of your list. Also, by giving away free things, companies can convince people to try new products. You might not want to try a new kind of shampoo if you have to pay for it, but you’d certainly be willing to give a free sample a try. You may end up loving it and switching to that shampoo for good, turning you into a paying customer. Another reason a company might give you free stuff is to complete market research. This is where getting free things can get a little complicated for some people because the products may not cost you money, but the offer may cost you a little time. A company might ask you to take a survey of your buying habits before they give you a free offer, or they may ask you to provide feedback on a regular basis as you try their product for free. Some people balk at the time commitment required here, but for other people, filling out some paperwork is a small price to pay for some free stuff. Of course, to convert you into a customer or to communicate with you about market research, a company will have to contact you, which is complicated area number two for freebie lovers. You will almost always be forced to hand over your email address in order to cash in on a free offer, and that is a recipe for opening your inbox up to a barrage of spam (many companies sell your email address to offset the costs of their free promotions, which means the number of people soliciting you can go through the roof very quickly). If you want to avoid this downside of freebie hunting, set up a special email address specifically for your freebie deals. That way all of your spam goes to this one address and your regular email you use with family and friends remains free and clear. One final note of caution about free stuff online: a lot of scammers have hit on the idea of using pretend freebie offers to solicit personal information about people or to convince people to send them money. Don’t send money, even for postage, to a company you don’t know and never, ever give out personal information online. No reputable company is going to ask for your social security number or bank account details for a freebie offer, so don’t hand them out to anyone. When in doubt, skip it and move to the next freebie. |
