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.

The History of Writing (history of writing) Writing is commonly used by billions of people each day. However, many of us don’t know the history of writing, and some of us would rather not ponder it for fear of getting a headache. Written communication is much needed today, and many societies could not survive without writing. Writing has a history like everything that is in existence today. The exact history of this form of communication may be clouded and even over exaggerated at times, but there are two known facts, writing has been used for a very long time and writing will be used for a very long time. The true beginning of writing is unknown, but it does have a comprehensive history. The first artistic paintings and writings were said to be done in the form of naturalistic paintings of animals and people in caves. The pictures were known as attempts to appease the spirits of animals that were needed to kill in the hunt. In ancient times pictures were also done of human beings. These pictures of humans were typically done in series, with a figure appearing in different physical positions progressively, which represented positions a ceremonial dance performed by ancient people. Progressively, the early societies began to stylize their messages, which were similar to using symbols to represent restrooms, handicap-accessible places, and international road signs. These stylized symbols are known a petroglyphs and hieroglyphs. The most famous system of hieroglyphs belonged to the ancient Egyptians who had hieroglyphics that were partially representational pictures that were stylized. Petrogylphs were often used by Native Americans as messages along trade routes, ritual information, and various other things. However, they were not as sophisticated as hieroglyphs. During this ancient period, Europeans preserved esoteric knowledge in runes and in an alphabetic writing system known as ogham. The Chinese culture also has a place in the history of writing. The culture began by writing like many others by using pictures then slowly moving to stylized pictures. However, over time the pictures became less representational and more abstract. Today, Chinese, Japanese, Korean, and other Asian languages are written with the use of ideeographs. An ideeograph is used to represent an idea instead of a word. Around 1700 B.C. a new form of writing appeared in the Middle Eastern cultures. During this time, the Phoenicians created an alphabet. This development was different from all others because the symbols represented sounds, not pictures or ideas. The combinations of sounds made up the words of the language, which was crucial in the history of writing. The alphabet developed by the Phoenicians spread to Northern Africa and became the system of the Arabs, and spread northwest to Greece. The Greek developed their own letters, which were modified even more to become the Cyrillic alphabets of Russia, the Balkans and the Romans. The Romans modified the alphabet and made it the alphabet that is recognized today. The history of writing developed even further into the 20th century. Following World War II, the Japanese and Chinese began to use the alphabet to represent the sounds of their languages. For these Asian cultures, the alphabetic system was easier to write by hand and to print economically, so it made life far simpler for those cultures. The artistic form of writing used by these Asian cultures will likely never die, but there are many advantages to using an alphabetic system, and many modern people of these cultures benefit handsomely from learning to read and write using the current alphabet. The history of writing is long and sometimes vague, but it can be seen as a necessary teaching that will help modern societies understand the importance of written communication, and understand how the world would be forever changed without it.

Non copyright music downloads Non Copyright Music Downloads Offer Growing Options for Music Collections Non copyright music downloads are growing in popularity and providing much needed exposure to many 'starving artists'. The truth of the matter is that many artists are turning to open source applications or creative commons licensing which allows them to provide their music to others while still retaining their ownership. It's a great idea that has actually worked quite well within the software community and is just now taking hold within the music industry. The idea of services such as this that offer non copyright music downloads to consumers for their listening pleasure is a relatively new concept that is beginning to take hold throughout the online music community. It is important to remember that while there are a few names that are recognizable and reputable in this particular industry there are also those that have less scruples than others and are more than willing to take advantage of music lovers for the fees they will pay and/or a credit card number and personal information. It is always wise to be aware of the information you are sharing online and to take great pains not to give information to companies that aren't absolutely secure and reputable. There are so many 'back room' websites that offer you unlimited music downloads for a yearly or lifetime subscription fee that sounds to good to be true. The problem is that many of these have a very limited selection of non copyright music downloads or quality music and only offer substandard and non mainstream music that no one has ever heard of or they offer music sharing that is not at all legal and puts you in a precarious legal position. The law holds you accountable for what you do rather than what you understand you are doing more often than not. Thinking you have non copyright music downloads is not the same as actually having them. So don't believe everything you see when it comes to defining legal and illegal music downloads. Find companies that have good reputations and don't go with cheaper services that are suspect and vague in their description of services. Non copyright music downloads or open source music is still relatively new. There are a lot of questions that leave a lot of room for misunderstandings, confusion, and consumers being taken advantage of. Educate yourself before subscribing to any of these services. Check out several do searches online to see if there is any negative feedback about these companies, read the feedback and see what people have to say. You can't believe all the negative you read but if many people complain about selection or quality it's quite likely that they don't have a good selection or great quality. Know what you want and find a service that will give it to you in non copyright music downloads. Another thing to know about non copyright music downloads is that many of these services are not offered free. There are expenses involved for the company, the hosting, website advertising, the fees they pay the artist, and any other number of fees-also keep in mind that this is a very time consuming business for them and they have overhead costs in addition to wanting to get paid as well. Remember this is a business for them. You should not expect less of open source music than you expect from other music that you pay a subscription in order to download. Non copyright music downloads are definitely the wave of the future and the technology had better be able to keep up with the demands of consumers.
