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.

Five Biggest Job Hunting Mistakes and How to Avoid Them Looking for a job can be a challenging experience. Between the resume writing and the interviews you can find yourself exhausted and ready to throw in the towel prematurely. Stay the course until you find the job you want. While you are on your job-hunting journey, here are five big mistakes to avoid when job hunting. Steering clear of these mistakes could make finding a job much easier. One of the biggest mistakes that people make when they are job hunting is not looking in enough places for jobs. There is a certain level of diligence you need to maintain when you are searching for a job. Look in newspapers, online and ask around. Of course, there are boundaries you should follow when looking for a job. First of all only apply and interview for jobs that you think you would take if you were offered the position. Do not apply for jobs that you are not qualified at all for or jobs that you do not have a clear understanding of. When applying for jobs, it is important to have a resume that is update and professional looking. If you are not a good resume writer, look at examples online or find a professional to do your resume for you. Employers will take one look at a messy or unprofessional resume and rule you out without ever meeting you. It is also important to be sure that you resume can be found online. There are plenty of job sites that allow users to post resumes. Some sites even allow multiple resumes to be posted. This is a great place for employers to locate your resume and contact you without you actually applying for the job. Lying on your resume can eliminate you from being a job candidate immediately. If you stretch the truth about your experience or the type of jobs you have had in the past, employers will think that you are a liar. If employers think you are a lair they will not feel confident about hiring you because you have already compromised your integrity. Tell the truth about your work and educational history. No matter what people may tell you, an honest inexperienced candidate is better than a lying experienced candidate. Have faith that you will be able to prove your worthiness for the position you are applying for without making up half-truths. Be sure that your contact information is correct and that you respond when you are contacted. No matter how busy you are, you need to check your e-mail and phone messages on a regular basis. If you do not respond to a call about a job this is a sign that you do not need employment that badly. Employers will move on to the next candidate if you are slow getting back to them. Candidates that are not prepared for their interviews are typically eliminated from the search before the interview is over. If you are late for an interview you have a big huge mark against you as soon as you walk in the door. Not being dressed in professional attire also will leave the interview with a very bad impression of you before you even speak. If you show up without a pen or copies of your resume you look like you are unfamiliar with the interview process. This, in turn, makes it quite possible that you are unfamiliar with other work place procedures. A good job hunt can land you the job of your dreams. When you are settled into your new job you will be thankful that you took the time to search for a job the right way.

A Top Notch Cover Letter Can Get your Foot in the Door If you have ever looked for a job, then you know that it is tough out there. Competition is always fierce, especially for those “dream job” type of positions – great company, great benefits, and great pay. If you want your resume to rise to the top of the pile in the Human Resources department and you want to get that call for an interview, then you need something to make your resume stand out from the rest. The best way to draw attention to everything you have to offer is to have a cover letter that jumps right off the page and grabs the attention of the reader. The cover letter is your first chance to make an impression, so make sure your cover letter makes you the one potential hire that is definitely going to be getting a call. Before you can get into the content of your cover letter, you have to cover your basics. You should never, ever have a “form” cover letter that you use with every resume you send. Tailor your cover letter specifically to each individual employer, mentioning their company and the position for which you want to be considered. Address the letter to the correct person – if you’re not sure who will be doing the hiring, call the company and ask. Don’t assume you can address your letter to the HR department and have that be close enough. Taking the time to write a personal cover letter to each company lets your potential employer know you pay attention to detail right off the bat. Of course, you should also make sure that your cover letter is grammatically correct and free of typos. A sloppy cover letter is a one way ticket to the trash can for your resume. Once you have your basics in order, you can turn your attention to what you are actually going to write in the cover letter. Your cover letter is your sales pitch to the company; you need to let them know why they should bet on your when they hire for the position. One great way to sell yourself is to show off how much you already know about the company. Let them know why you want to work there by specifically mentioning projects the company has been involved in that you admire or talking about the position of the company within the field. As you show off how much you know about the company, draw attention to the ways you can actively help the company grow and succeed by drawing parallels between your experience and their work. After you have shown that you have done your homework and know about the company, go into some detail about the unique aspects of your work history. Draw attention to any special achievements or awards and any educational background you have that makes you a good candidate for the job. Remember, your resume will be attached to the cover letter, so you don’t have to go into great detail. Just pick out the highlights that will make the reader want to turn the page and delve into your resume. How you close your cover letter makes as much difference has how you open it. State again exactly what job you want to be considered for, and suggest that you come in for an interview. You can also suggest a few dates and time for an interview to show that you are eager to move on to the next step. You should also give a time and date that you will call to follow up on your resume. A pleasant closing and your signature seal the deal on your winning cover letter.
