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 - Unix vs Windows-Based Hosting, Which Is Better? An operating system functions largely out of sight, or at least is supposed to. It doesn't matter to non-geeks how a file gets stored, or how memory is used, or how simultaneous processes share the limited resources available on a computer. These are among the basic functions of any operating system. Yet, you can find very passionate supporters - who offer very detailed lists of pros and cons - for every operating system. Why? Because, though the low-level functions of an operating system do their work out of sight, there are many other features that rise to visibility. Sometimes, they do so when they're not supposed to. Weighing the pros and cons objectively could consume a book. But to select a web host operating system, a manageable level of considerations apply. They can be weighed even by those who don't know a processor queue from a pool cue. Learning Curves For most web site owners, administering the site/server is just overhead. It's not something they take pleasure in doing and they have plenty of other things to worry about. Many wouldn't know how and have no interest in learning (rightly so, given their priorities). Consequently, ease of administration is paramount for such people. Whether a Unix-based site (usually Linux these days) is easier to administer than Windows depends on your current skill set and the type of tools and level of access the web hosting company provides. But in general Linux is more difficult to install and maintain than Windows and the learning curve is steeper. FTP and Control Panels Often, you don't have to care. For many, the operating system is fairly transparent. FTP file transfers to get a new web page up to a Windows server are very much like they are to a Linux-based site. The user/administrator simply doesn't see what's behind the curtain. Many companies provide other utilities that completely mask any awareness of the operating system underneath. When that's the case, the web site owner has no reason to care, until or unless they need or want to go 'inside the black box'. Performance Performance issues can be relevant in selecting which operating system host type to choose. But for the most part, that aspect is outside the web site owner's control. Overall performance can be good or bad on either system, depending on many factors that the publisher will rarely see. The issue is a wash, as far as tipping the scales is concerned. What is more likely to be seen by a web site owner, at some point in their (and their site's) development is the database product that can be used to store information. Databases Microsoft SQL Server is relatively simple to use, yet extremely powerful and can deliver great performance. But it doesn't run on Linux. At least, not without special software to emulate Windows, which usually kills performance. On the other hand, with a bit of time invested, MySQL isn't significantly more difficult to learn than MS SQL Server and there are many free installations. Cost may well outweigh other considerations for most on this issue. Programming Languages Last, but not least, there are differences in programming languages that can be (or at least typically are) used on Windows vs Unix. If you have programmers who are skilled in Visual Basic, ASP and other Microsoft technologies, then a Windows-based host will be your preferred choice. For Perl and PHP programmers, Linux is the more common platform of choice. No single factor can push you to one versus the other operating system. And, in the long run, it isn't the primary consideration, unless you just enjoy playing with operating systems. What Career Coaching Can Do to Help Land a Better Job A career coach is something many people have heard of but few actually understand what they do. Career coaching has become more popular in recent years, and they are actually used by many people who already are employed to help them stay on the right track in their career. If you are looking for a job, however, and especially if your job search is proving difficult and painful, a career coach might be just what you need to get your search on track. Career coaches get a lot of flack by trade. Some people laugh them off as the latest in the line of self help gurus that people spend a lot of money to see, often with mixed results. To some people, career coaches are up there with psychoanalysts and personal trainers – accessories of the rich but not very relevant to your every day kind of person. This assessment of career coaches might not be entirely fair, however. Career coaches can, and have, helped tons of people get on the right track in their job searches and have helped even more people not only find a job, but find a career that they love. So, just what can a career coach do for you? If you are job hunting within a certain industry, a career coach can help you narrow down your choices while simultaneously making sure you are putting your best foot forward when you go out there on the hunt. Sometimes, especially if you have been in a field for a long time, the skills you are highlighting on your resume are stale or the language you use to talk about your work history is outdated. In addition, a career coach can help you make sure that when you go into a job interview you can present yourself as on top of the latest developments in the field and as a person who could jump right into the job without needing a lot of training or guidance. The same goes for someone who is trying to get a job in a new field. A career coach will give you pointers about that field and the companies in the field as well as giving you general advice about the typical culture of that business – what kind of lingo is used, where the industry is centered, who the big players are, and even how to dress for your interview so that you look the part. Career coaches can also make sure your resume is in order and showing off your skills in the best light possible. This help a career coach provides when you know what kind of job you are looking for is all well and good, but they can do even more when you know you need a job, but you just don’t know what you want to do. If you have been frustrated in your career goals in the past, a career coach will work with you to decide exactly what kind of job you really want to have. They can help you figure out which industries are best suited to your interests, your skills and your personality. If you want to start your own business, they can walk you through the process from start to finish. A good career coach could be the key to finding the career of your dreams instead of just one more job. Last but not least, a career coach can let you know what you are doing wrong in your career. Do you have a problem with your interpersonal working relationships, or are you bad at delegating so you always end up doing all of the work? A career coach will work with your to set these problems right. When you need a better job, a career coach can clear the path for job improvement. |
