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.

Reinventing Yourself Can Make a Difference in Landing a Better Job Are you stuck in a dead end job that isn’t getting you any closer to your goals? Did you wake up one morning to find yourself knee deep in a career you never wanted and one that is not making you happy? Many people feel this way – it can be easy to “fall into” a career that you think is temporary and then get so caught up in the day to day aspects of the job that never quite get out of it. If you find yourself in this kind of rut, the good news is that it is never too late to make a fresh start. No matter what your age is or what stage in your career you are at, you can always reinvent yourself to get closer to that perfect job. All you have to do is work up the courage to make the jump. The first step in giving yourself a career makeover is identifying exactly what you want to do. While it may be true that there is always time to reinvent yourself and start over, if you have to go through the process too many times, you are only wasting valuable time that could have been spent doing what you love. Don’t fall into yet another career that isn’t all that is it cracked up to be. Think about the things that you wanted to do when you first entered the working world. What was your dream job then? What career field was your passion? Is it still what you want to be doing today? Discover your dream, and then start building your goals around it. Once you know what you want to do, the time comes to start researching it. How do most people get started in the field? Will you need to start your own business, or are there companies out there already doing what you want to do? What kinds of entry level positions are available? Will you be able to do this in your town, or would moving to another city mean more opportunities for you? Before you make the leap, research your job options carefully. You may need to plan financially for the step you are about to take, so do your homework up front. Talking to other people in the field you want to enter is a great way to get actionable advice from people who have been there. When you know what kind of experience you will need to get started in the field of your dreams, think about the experience you have had in the past, and what you have done that matches up. This can mean either work related experience or things you have done as a hobby or class you have taken in school. Be creative here – you may have experience you don’t even realize you have. For instance, if you want to open a bakery, and you are always in charge of the bake sale at your child’s school, this counts as experience. Comb through your history and pick out all of the things you have done that will give you a leg up in your new career. Last but not least, you have start creating a new image to present to the working world. Start over with a brand new resume, this time highlighting the experience you have this is relevant to your new career goals. Work on a great cover letter that explains your passion and why you want to switch fields. If you are starting your own business, work on building a website and creating a brand you can be proud of. The sooner you start living your new career, the sooner your dream job will fall into place.

Staying Computer Safe while Searching for Freebies on the Net Who doesn’t love the idea of getting something for nothing? Free stuff can bring a smile to anyone’s face, and the Internet is destination number one when you are looking for cash in on a few freebies. The downside of free stuff online is that if you aren’t careful, the free item could end up causing plenty of headaches and heartaches, not to mention a lot of cold, hard cash. If you want to score with free stuff online, make safety your number one priority by following these tips. First and foremost, treat your personal information like its cash. That might sound a little dramatic, but anyone who manages to steal your identity online is after one thing, and one thing only, your money and any addition money they can grab by cashing in on your credit. Protecting your name, address, credit card number, bank account number, phone number, social security number, and so on and so forth when you are registering for free offers is the first step to making sure you don’t get hustled when you’re just trying to enjoy a good freebie. That means that if you are asked for some personal information that you don’t feel comfortable handing out, let the freebie go. Likewise, make sure the site from which you are getting your free stuff has a privacy policy and that you know it, understand it, and can live with it. Speaking of that site that is handing out the free goods: just who are these people? If you were walking down the street and a shady looking person said they would give you a free DVD player if you followed them, chances are you would run the other way. Online, it is hard to tell the legitimate people from the people looking at you like a free lunch, but there are a few red flags you can look out for. Does the website look like it was thrown up in about 5 minutes, full of clip art and bad spelling? Is it hard to find information about where the website is registered, or where the business the website is supposedly promoting is registered? If the website purports to be affiliated with a certain brand you know, does it really look like it is, or does the logo look different/colors look off? If you can’t get a reasonable feel for who are dealing with online, don’t deal with them. Red flag number one? Asking for too much personal info should send you running. Another way to protect yourself is to build a virtual fortress around your computer. The net is filled with people who know how to walk right into your virtual home – your computer – and flip through everything you have on there, taking whatever they want. Many of these kinds of hackers draw you in by creating phony freebie websites. The way to keep them out is to keep your computer on lockdown. Make sure your firewall is stronger than you think it needs to be, and make sure it is always updated. Also, make sure you have antivirus software on the patrol for you and that you keep this software updated as well. Last but not least, keep those passwords in the vault, and make sure they are extra strong. No freebie website has any reason to ask you about the passwords for your accounts so don’t give them away – and don’t give them to anyone else online for that matter. Also, if you’re using your birthday or child’s name as password, don’t. Sure, it isn’t as easy to remember, but your password should be a random word and contain a collection of numbers and symbols as well. This will give you the extra layer of protection to make sure your online house is in order when you cash in on the freebies.
