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.
Copyright Music Infringement Copyright Music Infringement is Not Preferred Method for Music Lovers In recent years, copyright music infringement has seen an unprecedented leap in scope and scale. This is largely due to online services that allowed unchecked file sharing among their subscribers. While this abuse of copyright is not by any means limited to music, this is where the most profound effects of file sharing have been observed. Industry giants of file sharing are cropping up left and right with the demise of the pioneer for illicit file sharing, Napster. The Recording Industry Association of America (or RIAA) has made copyright music infringement their primary cause to fight. They estimate that peer-to-peer file sharing takes around 4.2 billion dollars each year worldwide from the coffers of the music industry. I really cannot blame them that is a fairly large chunk of change. The problem with their estimates however is the assumption that people would actually buy every piece of music they download or that they aren't buying the music they would have bought at any rate. While I by no means condone copyright music infringement or any other copyright infringement I do believe they are overestimating the damage to the industry that is being done by these file-sharing programs. One of the primary arguments that the RIAA is using in order to, hopefully, discourage people from not supporting their favorite groups and artists by buying their recordings, is the fact that new and struggling bands are less likely to continue making music because it will no longer be profitable. The bulk of musician's incomes are the result of royalties, which depend entirely on the sales of their albums. The RIAA is using the legal system to back them up by taking the fight to court. Recent claims made by the RIAA include one rather controversial claim that people ripping CDs they have bought and paid for does not constitute fair use because CDs are not "unusually subject to damage" and that if they do become damaged they can be replaced affordably. This assertion has raised more than a few eyebrows and is giving rise to opponents of the RIAA who claim that the lawsuits and crackdowns against those presumed guilty of copyright music infringement are actually hurting music sales and the profits of the music industry. During the height of Napster popularity (the hallmark by which all file sharing seems to be compared) CD sales were at their highest rate ever. People were exposed to music and groups they otherwise may not have heard without file sharing. As a result of enjoying the music by these groups people went out and actually bought the CDs of the music they enjoyed. It's ironic that the very lawsuits designed to stop copyright music infringement have actually managed to stifle file sharing enough that CD sales are dropping noticeably around the world. Opponents and critics also challenge that rather than being a source of copyright music infringement, peer 2 peer networks offer unprecedented exposure for new artists and their music. Another argument against the RIAA is that the real reason for the lawsuits against file sharer is because they want to keep the prices for CDs over inflated while keeping the actual royalties coming to the artists relatively low. The copyright music infringement claims made by the RIAA have become suspect. The music industry is currently working on ways where fans can legally download music. This will mean that fans have access to the music they love from their PCs and directly to their music playing devices without resorting to illegal copyright music infringement. The truth is that most people want to do the right thing and given viable alternative will elect to do so. Copyright Infringement Lawsuit Who are in Copyright Infringement Lawsuits? A copyright infringement lawsuit can be brought down for any number of reasons: someone using a song in a podcast or radio program, a writer ‘borrowing’ information from another work, the copying of video or mp3 off the internet without permission (or sometimes, even to another CD or DVD). Copyright infringement lawsuits are not generally brought to the average person, unless they’re downloading a LOT of music or movies, but usually for large operations: software pirates reselling goods on eBay or to some other unsuspecting victim, someone ‘sampling’ a song to make another, or maybe a person reselling mp3s online. When you understand the implications of it, copyright infringement lawsuits aren’t frivolous as some people may make it seem. For the most part, the average person’s familiarity with a copyright infringement lawsuit is taking down copyrighted material after receiving a nasty email. The use of works that are used in major record albums my major recording stars like Britney Spears or 50 Cent, people will begin copyright infringement lawsuits for songs that bear resemblance to another song. Usually these suits will be lost because it’s rather hard to prove inspiration, but they are rather costly and draining, especially if there isn’t a large backing legal team. Copyright infringement lawsuits for large enterprises can be rather costly and time consuming as well. If you work for someone, and you plagiarize someone on the company blog, the whole company can be sued, and you fired, for that infraction. Another large copyright infringement lawsuit is the eminent MySpace v. Universal Music Group, who is claiming that MySpace is knowingly committing copyright infringement by allowing it’s users to upload copyrighted material. Even then, Universal Music Group has been negotiating with MySpace and couldn’t come to an agreement – then they filed suit. Universal Music Group has an agreement in place with YouTube, where YouTube agrees to follow Universal’s rules. It’s worked out well thus far, and I think with an agreement in place ‘user created content’ will retain a destination on the internet. This is a testament we all need to be with social networking sites and ‘user created content.’ We need to watch ourselves, because many times we may not realize the veracity of our actions. Sometimes, people break copyright laws on purpose. There is a huge market in the dealings of pirated software – from Windows to Photoshop to The Sims. It’s very easy to share peer-to-peer, and because of that, people can resell ‘pirated’ for a high price – all profit. Or they’ll download MP3 and resell them; or eBooks. These people who resell these items get nasty penalties – with both copyright infringement lawsuits and criminal cases. They’ll pay a hefty fine and go to jail. As you can see, copyright infringement lawsuits can affect any one of us – from our friends on MySpace to our employer, to the computer geek down the street. It’s very easy to violate copy rights, and you have to watch yourself. The chances are good that you won’t be involved in a major copyright infringement lawsuit, but you still need to ensure you’re following the copyright rules of engagement. Copyright infringement lawsuits are important in determining what is, and isn’t, applicable to copyright laws. Because of these lawsuits, our laws have changed regarding fair use, internet use, and the Electronic Frontier Foundation and CreativeCommons.com has been formed. The lawsuits help us to understand what is, and what isn’t fair – and these organizations have helped the masses to understand what’s so important about copyright, and why we need to defend our freedom of speech. |
