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. Helpful Hints on Getting Better Respect in the Workplace Sometimes, an inhospitable work atmosphere can ruin the best job in the world. If you work in an office where people don’t respect each other and you feel undervalued and taken advantage of, then you are likely to give up and move on--no matter how much you love the work. When people work closely together, disagreements and problems are bound to arise from time to time. There are, however, ways you can get more respect in the workplace, so you don’t have to dread heading to the office every morning. As the old adage goes, you have to give respect to get respect. Are you doing everything you can to treat your co-workers with dignity and respect? Put another way, are you doing everything you can to avoid annoying everyone in the office? There are a lots of little ways you can make the day more pleasant for everyone, including showing up on time for work and for in-house meetings, not talking too loudly on the phone, keeping your personal cell phone ringtone on silent or vibrate, and cleaning up when you use the common break rooms and kitchen area. Things like spamming everyone in the office with incessant “funny” emails, sending political or religious emails (or challenging everyone on political or religious issues), or invading privacy by looking at someone else’s emails, phone messages, or mail are also not a good idea in the office setting. Then there are the big ones – you should never take credit for someone else’s work, talk behind people’s backs, lie, steal from other’s desks (even if it is just a post-it note or white-out), or have a general bad argumentative attitude. If you are doing anything of these things, trying to correct your own behavior is the first step to earning a little more respect in the workplace. What happens if you are doing everything you can and you still aren’t getting the respect you feel you deserve in the office? How you handle things may partly depend on who is showing you the disrespect. Are your subordinates treating you like you’re not the boss? In this case, having a little one on one conversation might do the trick. It doesn’t have to confrontational. You can simply point out that you are getting the impression that they may be having a little trouble with your leadership style and offer them a chance to raise any problems. If they bring up a legitimate problem, then there is something you can work on to make things go smoother in the future. If they can’t point to any one thing, let them know politely, but firmly, what you will need from them going forward in terms of respect. And then, stick to it and hold them accountable for their behavior. If your boss is not respecting you, things can get a little trickier. If your boss has a bad attitude, being pulled up on it by his subordinates is probably not going to do much to improve it. Your company may have a grievance policy in place to deal with issues like this, and it is best to go down this path when dealing with a boss with a respect issue. There are some respect issues in the work place that can’t be resolved with the softly, softly approach. If you are being persecuted on the basis of your gender, your race, your disability, or your sexual preference, you have a right to demand a stop to that at once. If the abuse is coming from your co-workers, go straight to your boss. If your boss is unresponsive, or if your boss is the offender, go right over their head, and keep going until you get some satisfaction. |
