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.

Web Hosting - Look Before You Leap Companies that offer Internet-connected servers that provide space and bandwidth for a domain, for one or more web sites, are called Web Hosts. Large companies have private networks that allow them to host domains on their own equipment and IP address range. But for the majority of those who want an Internet presence, a 'rented' web host is a necessity. There are a wide variety of hosting plans available. Some are free, others charge up to a $100 or more per month. Some provide nothing but a tiny amount of disk space and minimal network bandwidth. The web site owner is on his or her own for any thing else. Others offer a range of services, including server and email administration, backups, web site design assistance, troubleshooting and many others. In the world of web hosting, you may often find yourself sharing a server with anywhere from one to a thousand or more other web sites. That allows the web hosting company to keep equipment and staff expenses lower. Many web sites are simple and low-volume enough that the arrangement works fine. When you or one or more of the others grow, it may be helpful to consider a dedicated server. A dedicated server, as the name suggests, hosts only your domain. You can put one web site on it, or as many as you wish. You control the access. You may also, as an option, take over much of the server administration yourself. That may save you money on support costs, but cost you considerable time. If you don't have the expertise, you can end up costing yourself much more than you save. In order to carry out those administrative functions yourself, even if you hire help, it's desirable to have some technical knowledge under your belt. Some of that knowledge will be useful, even for day-to-day tasks apart from dealing with emergencies. FTP, email administration, backup methods and other technical areas are among the more common areas you'll need to be at least somewhat familiar with. When your web site grows to a certain size and level of complexity, you'll begin to find it worthwhile to look at implementing a database. But that brings with it a still higher level of ability, both technical and logistical or creative. Implementing a database can be relatively simple. Designing one that provides what you want, with decent performance and maintenance that doesn't become a nightmare, will take some careful thought. Not everyone has the temperament for that type of work, especially those who prefer graphical design, content creation or development, and the many other web site tasks that are part of every implementation. There are other, more low level administrative matters. Managing disk space, maintaining domain names, dealing with registration and changes, and a number of other 'utilitarian' tasks are also not everyone's cup of tea. Some understanding of how DNS works, as well as the design of the Internet itself, are helpful. That provides a good context for understanding the role of some of those tasks. When you begin to seek out a web host to implement a web site, consider all these factors and look in the mirror. What kind of web hosting you should pursue is determined by a combination of who you are and what's being offered. Look before you leap.

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.
