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.

Education Copyright Law The Nuts and Bolts of Education Copyright Law It is a wonderful thing that Education Copyright Law is available for educators. It isn’t only teachers that can take advantage of education copyright law. Students are also covered under education copyright law -- to a degree. Teachers are able to use copyrighted materials in their classroom and make copies of them. Students are also able to use copyrighted materials in school projects. The key to education copyright law is how often a teacher or student uses copyrighted material, in what way they are using it and how many copies they have of it. It is important that teachers and students do not cross the line of education copyright law or they could be in for some stiff penalties. It helps many students and teachers to learn what exactly is not copyrighted. Any work that is in the public domain is not copyrighted and can be used in school and for school projects. Work that is not in the public domain is copyrighted and if you use it you should make sure you fall within the fair use or education copyright law regulations. Many people do not know what exactly fair use copyright regulations are. When you are trying to see if you can use another’s words, you should keep a few things in mind. The answer to the following questions will help you gage whether you would be violating a copyright. First, are you transforming someone else’s work or are you copying it directly? If you are using another person’s work directly, for what purpose and how much of the original author’s work are you using? Many publishing companies have set rules on how much material they will allow to be quoted in other sources. Some of these ranges start at 100 words or less. However, there are truly no standards to go by, so be careful. You can not assume that keeping your copying fewer than 50 words will allow you to pass under the radar – especially if the original piece is hovering around 125 words itself! There is a greater amount of room to maneuver when it comes to technical writing. For instance, if you are writing a report on something that involves a lot of reporting from an expert, you would probably need to quote more of their work than you would a fiction novelist’s work. The fair use copyright law enables people to use portions of material that is copyrighted for the purposes of criticism or as commentary. Individuals who are involved in the distance education field should take a look at the TEACH Act that was made into law in 2002. This Act clearly outlines the requirements that a university or school must be in compliance with when it comes to transmitting copyrighted works via the Internet. The TEACH Act allows students and teachers to transmit copyrighted works, but they must be within certain guidelines. If the school or university cannot meet these guidelines, the material that is being transmitted via the Internet needs to fall within the fair use copyright act – or the individuals involved need to have permission from the copyright owner. If you are an educator and you are using copyrighted material make sure it falls within the education copyright law.

Keeping your Career Intact During Maternity Leave Since, for the most part, maternity leave in this country is not paid, the reality of returning to work after having a baby comes much sooner than it does in most countries. No one wants to return to absolute chaos after they have the baby. Cut down on the stress of going back to work by being prepared. The length of your maternity leave can determine the amount of stress you return to. If you are willing and able it is a good idea to work as long as possible. Of course, everyone is not willing and able. For those that need a longer leave, they should put some plans in place to make the transition back to work smoother. How long you are on maternity leave varies. However, if you plan on returning after you have the baby, you do not want to return to a totally chaotic situation. That means that you want to have the needs of your career in tact before you take your maternity leave. Nothing should interfere with your new addition to the family. While you are bonding and spending time with your newborn you do not want the stress of the office hanging over your head. Lay the ground work so that you do not have to worry about the office while you are away. If you are the boss, you have a lot more stress to manage. It is important that you leave a responsible and capable person in charge of things in your absence. Start training that person to deal with the aspects of your job that they will have to handle as soon as you know you are pregnant. Nothing is more annoying than getting “How do I…” phone calls when you are on maternity leave. If your job is massive, split the responsibilities between two employees. You do not want to split up the tasks among too many people because this can lead to confusion. Two should be the maximum. Be sure to leave things in order. If you are not the most organized person, get that way when you find out you are pregnant. While you are on maternity leave anyone should be able to walk into your office and find what they are looking for in a very short amount of time. If things are messy there is more of a chance for things to go wrong. If you are one of those women that needs to have an extended maternity leave because of pregnancy complications, don’t fret. Enjoy your time offer and relax but also, if you can, try to stay on top of what is happening in your career field. Take an online class and brush up on skills. If you are not sure you want to return to your 9-5, research a new career. The Internet has made working from home a very real and popular option. Search for a job that will allow you to stay at home but also bring in some income. Some jobs, such as Computer Programming, can fetch a pretty penny. Do some research and find out what will suit you best. Work part time until you are ready to have the baby. While some women are eager to take their maternity leave, others are not so excited about it. If that is the case, talk to your employer about working part time until you are due. Some women work until they go into labor. There is no need to do that if you are uncomfortable but if you are having an uneventful pregnancy and love your job, why not?
