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 Infringement Play It Safe: Making Sure You're Not Committing Copyright Infringement Copyright infringement is not an easy thing to explain. While it may seem as simple as not using someone else’s work, it’s not that easy. Thanks to the Electronic Frontier Foundation, and many other organizations, we have the ability to use others’ works – as long as we use it under ‘fair use’ laws. So what does fair use have to do with copyright infringement, and how can you utilize it? Fair use laws are the conditions in which you can use a copyrighted work without having to pay someone royalties. This includes when you use a copyrighted work for educational or instructional uses, criticism of the work, commentaries on the work, news reporting about the work, teaching on the work (including multiple copies for classroom use), scholarship uses, and research. This is talked about fully in Section 107 of the Copyright Code (commonly called Fair Use) and is available for you to read at your local library. Copyright Infringement in day-to-day life Sometimes, if you’re writing a paper for work or school, or if you are creating a Power Point presentation, you need to use someone’s work that is already in copyright. So how do you use it without committing copyright infringement? All you have to do is ask – the worst they can say is no, right? But, if they do say no, there are several items in the public domain which may help you to finish your project without having to commit copyright infringement. What is the public domain, and how does it relate to copyright infringement? Material that is not copyrighted is considered in the public domain – you cannot commit copyright infringement on works in the public domain. These works include things that the copyright has expired on, or is not copyright-able – such as government publications, jokes, titles, and ideas. Some creators (writers, musicians, artists, and more) deliberately put their work in the public domain, without ever obtaining copyright, by providing an affiliation with Creative Commons. Creative Commons allows people who create materials to forfeit some, or all, of their copyright rights and place their work either partially or fully in the public domain. So, how do I ensure I’m not committing copyright infringement? First of all, if you’re going to use someone else’s material, you may want to check the public domain to see if something is suitable for use, instead of trying to use someone else’s copyright. However, if you can’t find something suitable (and you can’t create something yourself), the next best thing (and your only legal course of action) is to find a piece that is in copyright, and contacting the copyright holder. When you contact the copyright holder, make sure you tell them what you want to use their piece for – whether it’s for your blog, podcast, or report – and ask them if you can use it. You may have to pay royalties, or an attribution in your piece, or a combination of both. The creator may also place many limitations on when and how you can use their material. Follow all these instructions they give you, and you’ll be free and clear to use their work as you want. Once you have permission to use a copyrighted work, you need to make sure you stay within the agreed-upon boundaries - if you veer outside their agreed terms, you may open yourself up for a copyright infringement lawsuit – which can be nasty, costly, and time consuming. If you’re in doubt, before contacting the copyright holder, contact a copyright lawyer to ensure you’re following the law – and protect yourself!
