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.
Education Copyright Law The Nuts and Bolts of Education Copyright Law It is a wonderful thing that Education Copyright Law is available for educators. It isn’t only teachers that can take advantage of education copyright law. Students are also covered under education copyright law -- to a degree. Teachers are able to use copyrighted materials in their classroom and make copies of them. Students are also able to use copyrighted materials in school projects. The key to education copyright law is how often a teacher or student uses copyrighted material, in what way they are using it and how many copies they have of it. It is important that teachers and students do not cross the line of education copyright law or they could be in for some stiff penalties. It helps many students and teachers to learn what exactly is not copyrighted. Any work that is in the public domain is not copyrighted and can be used in school and for school projects. Work that is not in the public domain is copyrighted and if you use it you should make sure you fall within the fair use or education copyright law regulations. Many people do not know what exactly fair use copyright regulations are. When you are trying to see if you can use another’s words, you should keep a few things in mind. The answer to the following questions will help you gage whether you would be violating a copyright. First, are you transforming someone else’s work or are you copying it directly? If you are using another person’s work directly, for what purpose and how much of the original author’s work are you using? Many publishing companies have set rules on how much material they will allow to be quoted in other sources. Some of these ranges start at 100 words or less. However, there are truly no standards to go by, so be careful. You can not assume that keeping your copying fewer than 50 words will allow you to pass under the radar – especially if the original piece is hovering around 125 words itself! There is a greater amount of room to maneuver when it comes to technical writing. For instance, if you are writing a report on something that involves a lot of reporting from an expert, you would probably need to quote more of their work than you would a fiction novelist’s work. The fair use copyright law enables people to use portions of material that is copyrighted for the purposes of criticism or as commentary. Individuals who are involved in the distance education field should take a look at the TEACH Act that was made into law in 2002. This Act clearly outlines the requirements that a university or school must be in compliance with when it comes to transmitting copyrighted works via the Internet. The TEACH Act allows students and teachers to transmit copyrighted works, but they must be within certain guidelines. If the school or university cannot meet these guidelines, the material that is being transmitted via the Internet needs to fall within the fair use copyright act – or the individuals involved need to have permission from the copyright owner. If you are an educator and you are using copyrighted material make sure it falls within the education copyright law. Achieving a Better Family and Work Balance Makes for Better Job Performance Are you constantly working after hours and weekends at the office? Are beginning to forget what your family even looks like? Many people find themselves in this predicament. Work seems to get more and more demanding with every passing day, and to stay on top of your game at work, you feel like you need to put in long hours. The flipside to this is that of course when you are at the office, you are away from home – away from family dinners, play time and your kids’ sporting events or school plays. You may feel like your hands are tied – that no matter how much you want to be more involved with your family life, you have to keep working as hard as ever to make sure your family is provided for in the long run. The truth is, however, that you may be doing yourself a disservice on both fronts. Studies have shown time and again that well rested workers with well balanced lives are more productive in the time they do spend working. In the end, the best way to be a stand out worker at the office is to be fully involved and present in your family live. But wait, you say, “I’m working practically around the clock now, and everything still isn’t getting done.” However, maybe the problem isn’t that you aren’t working hard enough. Maybe the problem instead is that you aren’t working smart enough. Think about the way you spend you working day. Are you taking on more responsibility than you need to, instead of delegating tasks to others? Are you spending a lot of time chatting in the break room when you run for a cup of coffee? Are you procrastinating so that big projects require you to work all-nighters instead of spreading out the work? Keep a journal of all of your activities at work for a few days. You might be surprised to see how you are really spending your time and in what areas you could make improvements. Simply staying on task and delegating effectively could get you home in time for dinner. When you have done everything you can to make your work habits as productive as possible, it is time to turn to other ways to balance your work life and your family life. Rule number one is the hardest one for most people to follow you – draw clear lines of distinction between work time and family time. Family time isn’t really family time if you are constantly on your cell phone making and receiving work calls or if you are on your laptop for the entire family vacation. When you’re working – work. When you’re with your family – concentrate on them. The time you spend actually taking a breather from work will recharge your batteries and make you a better worker when work time rolls around again. Next, you have to evaluate your priorities. Maybe working around the clock will help you make partner faster, but at what cost? Decide if seeing your daughter’s soccer game every week is more important to you than moving up the corporate ladder quickly, and make adjustments in your schedule appropriately. There is no right or wrong answer, but deciding where you priorities lie will make scheduling easier for you. With your priorities in mind, see what work options are available to you to help you meet them. If you want more time with the kids, see if your office offers flex time or part time hours to help you meet your family commitments. Last but not least, don’t feel guilty about taking time with your family. Not only is this time important to your family, you can rest assured that the time out from the office stress will make you more productive when you return to work. |
