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.
Events of copyright infringement The Events of Copyright Infringement: Innocent People Infringing Accidentally Copyright infringement is in the news a lot lately – it’s hard to miss stories about kids being carted off to jail or seriously fined for downloading music or movies off the internet. I’ve even heard about a lady was fined for tens of thousands of dollars because of the events of copyright infringement – her grandson downloading music, and she couldn’t prove it wasn’t her. The events of copyright infringement are complicated – and not easy to define. Surfing the internet has its advantages and disadvantages, that’s for sure. We’re able to find useful information quickly, but how close are we pertaining to copyright laws? Do we even know what is and is not acceptable? A couple of the more pertinent questions have been asked below: If you hear a great new band, and then download a song from MySpace, is that legal or not? The events of copyright infringement are not only limited by Kazaa, Morpheus, or some other file sharing peer to peer (P2P) service. If you download a song - no matter if you’re on a website or a MySpace page - and it isn’t coming from the artist themselves, you may want to think about downloading it. Chances are, if it’s not coming from them, you can’t have it – unless it is under a Creative Commons License. Creative Commons gives the exact ways in which you can use the license – and many times those are completely free and legal to download – so make sure you check if it’s under a CC License. If I’m writing a paper, or article, and I want to quote another website, can I? First of all, did you know the minute you write or create something, you hold the copyright to it? ESPECIALLY if you’re writing it online – it’s very easy to track things in the internet page. So, if you’re writing a blog, all the things you’ve written (no matter good or bad) are there permanently, thanks to archive.org, and you can review last versions of your web pages. Sometimes, people we can use – rather heavily – someone else’s work in our own, and think we’re small and anonymous. That no one will notice by the time you get it down – you’re just ‘borrowing’ it. Before you begin quoting anyone’s website – from CNN to your local neighborhood hardware store – you need to ask the person who holds the copyright if you can. Usually, they’ll let you if you attribute to them. Depending who you talk to, you’ll either have to pay royalties or license rights to republish. If you don’t ask before you quote, you’re beginning the events of copyright infringement and you are opening yourself up for a lawsuit. As you can see, the events of copyright infringement can begin at any time, beginning with normal ‘everyday’ activities. It’s just as easy to infringe on as it is to be infringed upon. Make sure you check your copyright using CopyScape or some other service, and you can check your work against other works on the internet, and make sure that you’re not infringing someone or vice versa. In this day it’s easy to protect yourself from getting infringed upon, and the events of copyright infringement are easy to track. It’s easy for innocent people to get caught in copyright infringement, like children they didn’t know what they could and couldn’t do. Make sure, in all you do, that you’re striving to do the best you can, and you’ll be certain not to fall victim to your own infringing demons. 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. |
