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.

Craigslist a Great Place to Find Free Stuff ? While Exercising Caution of Course Craig Newmark of San Francisco founded Craigslist in 1999. Craigslist is a web page that offers anybody to sell or by articles virtually free of charge. Some of the categories such as job ads in some of the major cities have a charge, which is the funding for all the other private, free ads on Craigslist.

Therefore, it is not unusual to find car ads, fitness equipment, baby clothing and items, furniture and more on the web site. Posting is for most classifieds free and there are also no fees for anything else. In contrast to some other pages, posting a used children?s toy, a piece of furniture or similar as well as anything else is completely free. The seller has the possibility to stay anonymous till shortly before the sale, when the seller decides to hand out his or her telephone number or address for sale purposes only. Of course such classifieds and advertisements can also be cons and need to always be handled carefully. Generally a good judgment of the price and offer helps to prevent from falling for fraudulent classifieds.

Music Copyright Law Are You Violating Music Copyright Law? With the popularity of the Internet, many people are violating music copyright law and do not even know it. Music copyright law can be very tricky. There are multiple music copyrights that you must keep in mind ? lyrics, composition and the recording of the music by an artist. Using someone?s music may involve you acquiring many different licenses such as mechanical, synchronization, performance and publishing licenses. Music copyright law has separate copyrights for the vocal or instrumental recordings of a composition or performance and the copyright of the written lyrics and music. Standard music copyrighting practices usually entail that the writer of the song retains the rights to the right to the music composition which the studio that did the recording of the music holds the rights of the recording. Music copyright law can get very complicated. It can involve negotiations with the writers, producers, agents, heirs and more. Many artists and studios are upset with the decline in music sales. They are attributing this decline to people who are violating music copyright law by downloading music on the Internet. Music files are under the same copyright law as music recordings and the owners of these copyrights are entitled to royalties or compensation for the music that people are illegally downloading on the Internet. The simple fact is you are stealing if you make copies of copyrighted music recordings without authorization to do so. If people were sued for the music they have downloaded illegally, it could result in thousands of dollars. Music copyright law states that it is illegal to duplicate and distribute creative work. If you send someone an email with a song that you have illegally downloaded on the Internet, you could be in for some serious trouble. To put it bluntly and plainly, if you download (or upload) music that is copyrighted without permission to do so, you are breaking the law. Many people violate music copyright law and do not even understand how their actions are criminal. If you purchase a music CD you can make a copy of it for yourself on your MP3. However, if you then use that recording and put it on your website or blog and make it available for everyone to download, you are performing an illegal act. Even if you join a site and pay a fee to download music you are in violation of music copyright law. This may sound like something that would never come back to haunt you. After all, if you were caught, it would be a first time offense, right? Well, you should know that there have been first time offenders who have been fined up to $250,000 and up to five years in jail for violating music copyright law. It is so much easier to go out and pay 20 bucks for a CD. Whether you are uploading music or downloading music, educate yourself on music copyright law. No one wants to ruin their financial future and face jail time. Enjoy music, just do it the right way!
