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.
How to copyright music How to Copyright Music for the Beginner For those wondering how to copyright music the answer can be both long and short. The first thing to remember is that most people are confused about exactly what it means to actually copyright music. Music is actually copyrighted as soon as it is presented in a fixed form. It doesn't really matter whether that fixed form is as written sheet music or as a recording. Most people are looking for solid legal protection and while a copyright is good to have, it is essentially worthless unless you've actually gone to the effort of also registering your copyright. Rather than asking 'how to copyright music', perhaps the better question would be 'what do I do now that I've copyrighted my music?' It doesn't really matter what you call it unless you're moving around in legal or industry circles I suppose, but I've always felt that it's a good idea to have a clue about the process in which you are embarking. Now that we've answered how to copyright music, it's time to move on to the real issue, which is registering your copyright. Music is registered through the U. S. Copyright Office. You will need to fill out an application, pay a fee, and provide a copy of your music. As far as government dealings go, this is one of the least painful. Even the fee is marginal when you consider your 'hopeful' future profits and royalties. All that aside, there is something that is massively satisfying about knowing how to copyright music and having your first piece of music registered. Music is an art form and the ability to write music is nothing insignificant. It is a real talent that is actually quite rare. Many popular musicians today use music that has been written by others either in addition to or rather than music that they have written themselves. Even if you aren't a talented performer, it doesn't mean that your music will never be seen or heard or that you should not bother learning how to copyright music. You just might find that you are more in demand for your particular talents than you would have ever dreamed possible. The big thing to remember though is not to sit around wondering how to copyright music but to get out there and go about the process of creating and making more wonderful music to share with the world. It takes all kinds of music to keep this world turning and there is someone out there that is waiting to hear the music that you create. The process of how to copyright music is completely free. The process of registering your copyright is worth every penny you will spend. It is important to protect your music now more than ever with piracy and widespread downloading providing significant reductions in profits for everyone involved. The music industry is also a very fickle industry and you need to maximize your profit potential and usefulness. Once you understand how to copyright music, you need to make sure every piece of music you have has been copyrighted, then you need to go through your music and systematically register each and every piece as well. Even if you must do one piece at a time until you manage to register the copyright on them all, it is much better to be safe than sorry should you ever go to trial in a copyright infringement case. Also remember to pay it forward and support up and coming musicians by sharing the information of how to copyright music and how to register copyrights as well.
Web Hosting - Redundancy and Failover Among the more useful innovations in computing, actually invented decades ago, are the twin ideas of redundancy and failover. These fancy words name very common sense concepts. When one computer (or part) fails, switch to another. Doing that seamlessly and quickly versus slowly with disruption defines one difference between good hosting and bad. Network redundancy is the most widely used example. The Internet is just that, an inter-connected set of networks. Between and within networks are paths that make possible page requests, file transfers and data movement from one spot (called a 'node') to the next. If you have two or more paths between a user's computer and the server, one becoming unavailable is not much of a problem. Closing one street is not so bad, if you can drive down another just as easily. Of course, there's the catch: 'just as easily'. When one path fails, the total load (the amount of data requested and by how many within what time frame) doesn't change. Now the same number of 'cars' are using fewer 'roads'. That can lead to traffic jams. A very different, but related, phenomenon occurs when there suddenly become more 'cars', as happens in a massively widespread virus attack, for example. Then, a large number of useless and destructive programs are running around flooding the network. Making the situation worse, at a certain point, parts of the networks may shut down to prevent further spread, producing more 'cars' on now-fewer 'roads'. A related form of redundancy and failover can be carried out with servers, which are in essence the 'end-nodes' of a network path. Servers can fail because of a hard drive failure, motherboard overheating, memory malfunction, operating system bug, web server software overload or any of a hundred other causes. Whatever the cause, when two or more servers are configured so that another can take up the slack from one that's failed, that is redundancy. That is more difficult to achieve than network redundancy, but it is still very common. Not as common as it should be, since many times a failed server is just re-booted or replaced or repaired with another piece of hardware. But, more sophisticated web hosting companies will have such redundancy in place. And that's one lesson for anyone considering which web hosting company may offer superior service over another (similarly priced) company. Look at which company can offer competent assistance when things fail, as they always do sooner or later. One company may have a habit of simply re-booting. Others may have redundant disk arrays. Hardware containing multiple disk drives to which the server has access allows for one or more drives to fail without bringing the system down. The failed drive is replaced and no one but the administrator is even aware there was a problem. Still other companies may have still more sophisticated systems in place. Failover servers that take up the load of a crashed computer, without the end-user seeing anything are possible. In fact, in better installations, they're the norm. When they're in place, the user has at most only to refresh his or her browser and, bingo, everything is fine. The more a web site owner knows about redundancy and failover, the better he or she can understand why things go wrong, and what options are available when they do. That knowledge can lead to better choices for a better web site experience.
Understand Group Publishing (group publishing) When you want to have one your books published, you will work hard to get your book finished and then you will seek out a publisher. Sometimes it is very hard to find the right publisher, but the good news is that there are several different types of publishers that you can use to get your works on the market. Large companies are not your only option. The world of publishing difficult to break into and if you get an acceptance letter--that is only the start. There are many types of publishing companies out there and they all have a different way of publishing their products. Here is a look at some of the more common types of publishing including group publishing. Group Publishing: Group publishing is the process in which a large company publishes your work in the name of a larger company. For example, there are big name publishing companies out there. They operate smaller group publishing companies. The larger publishing company serves as a kind of umbrella over the smaller group publishing companies. Sometimes these companies operate several smaller companies that produce different genres of writing and books. This is also sometimes called trade publishing. For example, a large publishing group may produce best selling adult novels, but may also operate under a smaller name to produce certain non-fiction books, cookbooks or children?s books. Group publishing is a popular way to publish a book. Educational Publishing: Besides trade publishing, there is also educational publishing. These are companies that deal specifically with educational material. They may deal with only college textbooks, or they might deal with textbooks and materials for grades K-12. Besides textbooks, these companies might also produce other forms of educational material, which include posters, workbooks, CD-ROMS, software, testing material and maps. There are several big name educational publishing companies. University publishing?University Press: This type of publishing is not like group publishing and it is not the same as scholarly publishing. These types of companies are usually non-profit and are run by universities, colleges and even sometimes museums or other organization. These usually publish books by scholars and other specialists and they usually are used within the university system. Sometimes these books do get published by a larger trade publish; however, they do not market these types of books. Independent publisher: Independent publishers are often the best way to get your book published if you cannot find a publisher to produce your book. These are generally smaller companies that are privately owned. Many times, these companies only publish a handful of books each year and they usually are about certain subjects. They have the freedom to publish just about anything they wish. Software and other Media: You might not consider software and other types of media as being a publisher, but they are. Think of all the e-books, CD-ROMs and even books on tape that are on the market. These have to be published, too. These types of companies are often associated with larger trade publishers. In fact, many large publishing companies have their very own media publisher in house to take care of this type of publishing. It is a very large business and these types of publishers are just as important and lucrative as the large trade publishers. As you can see, there is a whole world of publishers out there waiting to get your book or other media published. If you do not have luck with a large trade publisher or group publisher, then don?t give up. Keep looking and the different types of companies out there until you find one that wants to work with you and your book.
