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 "Catch" to Some of these Freebie Sites Remember that old saying, "There's no such thing as a free lunch?" Well, it's not true?there are plenty of freebies out there. However, there are some things you should know about if you are going to go after these freebies. The World Wide Web is awash with web sites that like to offer visitors with loads of tempting freebies. But although many of these are legitimate offers, there are some things you should know about these freebie sites. Here are some things to know about these freebie sites. Getting Things for Free?A Caveat Here is the basic caveat when it comes to these freebie offers?there is usually something you will have to endure in order to get your freebie. Although you may not have to make any sort of financial contribution or monetary expense, you will have to pay in some small non-monetary way. Here is a quick rundown of various kinds of 'catches' that you may come across as you seek out the best of the web's freebies. Watching Ads Before You Get to the Good Stuff One of the most common techniques that websites will use before you can get access to their freebies is to force you to watch ads. There are many different versions of this method. Many sites that promote freebies will support their site through advertisements. Most advertisements show up as pop-up or banner ads. Some websites also use video websites. With the ubiquity of high speed Internet, video ads have lately become the preferred method of advertisement on many websites. The less subtle of these ads are the pop-up and banner ads. Pop-up ads are often quite obtrusive and they can interrupt your enjoyment of the website. You might want to avoid ad-based freebie sites at work, as these can often interfere with your screen. Many popular freebie websites also offer ad-free versions of their content. This may be something to consider if you really find the website's content valuable. Be Wary of Automatic E-mail Sign-Ups Many freebie websites will sign you up automatically for their email newsletters. The worst-case scenario is when the website allows its partners to bombard you with email ads. What is the best way to avoid getting on an unwanted email list? Read the fine print, and whenever you get the option, uncheck the opt-in box at the very bottom of the page. Take Care of Your Privacy Many sites that offer freebies make money by selling the personal information that they gain from their web traffic. In order to avoid having your personal information being sold, you should avoid giving your personal information to websites that can't provide you with an upfront privacy policy. You should also look for the TRUSTe seal that ensures your personal information is kept secure and private. Also, never provide more information than you need to provide. Avoid Large Downloads Whenever Possible Another thing you should watch out for are large downloads. Although there are many legitimate large downloads out there, you should avoid sites that don't tell you exactly what you are downloading, how long the download will take, and how big the file size is. Watch Out for Disappearing Websites If there is one thing to know about freebie websites is that they are often 'here today, gone tomorrow' type enterprises. Many freebie websites simply don't survive for very long. You should think hard before committing to a website that offers free services that you will have to depend on. The last thing you want is to depend on a website's services, and then have those services disappear or suspended. Copyright lawyer rating Determining what's in a Copyright Lawyer Rating You can find a copyright lawyer rating these days by doing a quick search online or by subscribing to a mailing list to the copyright lawyer guild. What goes into determining a copyright lawyer rating may be how many cases he/she has won or lost? The person that has won the most cases will be at the top of the rating chart, however someone that just comes in may be at the bottom for lack of experience. If you are searching for a copyright lawyer you will want the best but keep in mind that if they already know their copyright lawyer rating is high, their price might be raised more than the others in the field. So, make sure this is someone you want to represent you or to do your filing. If you are simply getting a copyright you probably don?t have to have the best and can go with your average rating. Someone suing you for copyright infringement or something else means you may want the best; you don?t want one that had a bad copyright lawyer rating. Do you? Today many companies are offering their own little search areas for towns, you might find a whole list of companies that need reviews and chances are those that are all bad rating are from one person. These sites are very new and popping up everywhere, the only way to find out how true the copyright lawyer rating, is by asking them. Another way they do a copyright lawyer rating is by passing out a few sheets of papers with a bunch of copyright lawyers names on them and having their peers rate them. I don?t really consider this fair because someone with the same amount of time and wants to be top in the field may mark their competition down just to get up on top. Not to mention how can they rate them when they may have never heard of them. Do you give that person a bad rating or a one star because you have no clue how they perform? Do you leave it blank? Find out why a copyright lawyer rating got the marks they did. Keep in mind that a client that didn?t win a case can have it out for them and rating them bad or review them as bad in every site that they can, which can cause a big drop in ratings, especially if they are new. Not all lawyers like that fact that just about anyone can rate them online these days, it was easier when their ratings only went with what cases they dealt with, how many they represented and their win/lose streak. There is a website called Martindale, it gives you ratings of many lawyers. This is a great site to come view to find lawyers in all types of fields, not just copyrighting. Explore it, there are a ton of reviews written by lawyers and clients, there are also legal articles, cases, events and much more for you to look at. Don?t forget about the peer ratings, which you can find person most qualified to help you. This is one place that does seem fair when giving out their copyright lawyer rating, they make sure that the top person can only be rated if they?ve been in that field for over 10 years, which makes it fair to a person that has very little experience. They won?t be on the rating list which means they won?t be at the bottom of the list. Remember, if your copyright lawyer rating isn?t up there doesn?t mean he/she is bad, they may have requested not to have it published or may not have been in the field long enough to be judge. The best judge for them will be you. |
