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.

Following Up on Fallacies about Getting Free Stuff “Free stuff” – the mere whisper of the words is often enough to make many people throw common sense out the window and head for the free goods like a missile to a target. And then there are those people whose eyes glaze over when they hear those words, because they can’t believe anything worth having can actually be free. The truth about free stuff is really somewhere in the middle. Yes, you can really and truly cash in on many freebie deals for things that you want to have, but a healthy sense of cynicism about free gear is also useful. Here are some of the important things to keep in mind about free stuff. The first myth you should throw out the window is that nothing good comes for free. The fact of the matter is that the price tag on a good doesn’t always match up to the quality, and there are many great free things out there. Case in point: music. Sure, everyone has heard the scare stories about file sharing online, and maybe some big record labels will come after you if you focus on their artists. Dig a little below the surface, however, and you can find a whole new world of really great bands that are more than happy for you to listen to their music over and over again. The same goes for free software. People on the cutting edge of technology who have a passion for creating new and efficient applications often develop open source code software. They’re doing it for the love of it, and they often have more talent than any ten suit-and-tie tech guys trying to hock their latest product for a mega profit margin. Here is where the reality part comes in, however. Yes, you can find wonderful things that are completely free – but yes, you can also find a lot of free things that aren’t worth your time at all and in some cases can cause you a lot of trouble. The net is a great place to fall victim to a “free stuff” scam, but you can also sometimes come across these scams in the mail as well. If something is free, but requires you to give your credit card number or bank details, run the other way. Another myth people have about free stuff, especially free stuff on the internet, is that when you try to cash in, the only free stuff you will be getting is an inbox full of more spam than you can handle. The truth about this is, well, that is can certainly be true. Many companies give away free things in exchange for your email address, so they can try to hit you up to purchase things in the future. What makes this a myth, however, is that it can be avoided. If you don’t want to choke on an inbox of spam, and who could blame you, set up a special (free) email account that you will use exclusively for freebie hunting. You’ll have the best of both worlds. The last myth about free stuff involves the “catch” people are always looking for. Often, for free stuff, the catch is a bit of junk mail or email or the fact that you have to submit to a time consuming survey. Sometimes, the catch is that if you get free stuff through a trial offer, if you don’t cancel it, it keeps coming, and this time you have to pay. The truth about these catches is, however, that the catch is in the eye of the beholder. These things don’t make products any less free; so don’t write off every free offer offhand. You might just find a catch you can live with to get a great free product you really want.

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.
