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.
Web Hosting - Email Issues When you build a web site, you often provide a means for users to communicate with you. One of the most common 'add-ons' to a web site is the addition of some kind of email access. Email is used to sign users up for newsletters, provide communication for administrative issues and a hundred other uses. But, as everyone sadly knows, email problems can occur. Virus infection is among the most common, though the situation is actually better today than in the past. Huge efforts, and some progress, has been made over the past 10 years to reduce the number and severity of virus attacks. Hackers haven't surrendered, far from it. But they're on the defensive like never before. Many of those viruses were (and are) spread through email, usually in the form of email attachments. That's the source of the now-common advice never to open an attachment from someone you don't know. Professionals will often extend that advice to suggest you never open an attachment that's unexpected, even if it's from someone you know. Well-meaning, but computer-challenged friends often accidentally forward virus infected emails. Spam has taken over the top spot for email annoyances. It's estimated by various different professional sources that 92-97% of all email sent today is spam. While the definition varies, spam is generally regarded as any unwanted commercial email sent by someone whom the recipient doesn't know or have a business relationship with. Spam clutters email inboxes, requires people to sift through to find valid messages, and often contains offensive messages in some form. But, it's a fact of life and isn't going away anytime soon. Even though laws are in place, thousands of spammers continue to risk fines or jail for the chance of making money from that small percentage who will open the unwanted email. Other forms of email problems are even more severe for many web site owners. When the mechanisms fail that they rely on to send and receive messages to and from their users, that's a problem. Dealing with those problems can range from sending an email or instant message to an administrator, to tracking down the right person to get your site removed from a blacklist. Email is the communications vehicle of choice for millions everyday. When the system burps, someone has to take time to do something about it. Often, that means relying on a person who is already overburdened with too many issues to resolve. So, besides pointing out some sad facts or complaining, what's the point? All of the above shows just one more area you should look at when selecting a web host or deciding whether to move to another. Just as with server or network administration, companies vary in their ability to deal with email-related issues. Some are responsive and super-competent. Others, are simply indifferent or worse. And many are in between. Email administration, like server maintenance or network management, is a professional specialty. Skill in one does not necessarily mean quality work in another. Finding a web hosting company and/or system that has few email problems, and solves them quickly when they occur, is an important task. Spend some time researching who provides superior support in email. You'll be happy you did. The Business of Self-Publishing (self publishing) Self-publishing has become a common practice for many writers. Writers’ reasons for self-publishing are varied, but it is commonly known that many writers want the accolades of having published work, no matter who publishes it. The freedom and business aspects of publishing work independently are desirable to many writers. A self-published writer is one who is in control of every aspect of their published work. The term self-publishing is defined as the publishing of books and other media by the authors of those works, instead of being established by third-party publishers. The advancement of technology has caused an increase in the self-publishers world, but it still only represents a small percentage of the publishing industry in terms of sales. The proliferation of media channels and web logging has contributed to the increase in self-publishers. The business of publishing books and other media independently is one that is unique and different from any other business. The most distinguishing characteristic of self-publishing is the absence of a traditional publisher. The author of the content takes on the role of the traditional publisher. The author is given editorial control of the content, arranging for printing, marketing the material, and distributing the material to consumers and retailers. The published books may be printed on demand with no inventory, which places a large amount of financial risk for the venue on the author’s shoulders. Many self-published authors end up subsidizing their work rather than making money from it. Digital printing technology has made it possible for the self-publishing concept to become mainstream in digital photo book printing. Self-publishers are able to get individually printed photo books from firms like Apple’s iPhoto, FotoInsight, Snapfish, and Printing-1. The motives for publishing work independently are varied, and there are numerous reasons for choosing to self-publish. One common reason is that the work of the author is not of interest to the commercial publisher, and otherwise not marketable. Some other common reasons for self publishing include an author’s preference to retain complete editorial control over content. Many writers are unwilling to compromise when it comes to the editing of their work, and some prefer to have their work presented “as is.” Writers may also be denied publication because they are unknown and don’t have a substantial resume. Self-publishing may also be an alternative for writers who have written material on a popular topic but that is only of interest in a small geographic area. Topics that address an obscure topic in which few people are interested may also be denied publication by commercial publishers. Writers of controversial works may also choose to self-publish, as many traditional publishers refuse to work with controversial writings. There are also some authors choose self-publishing because they want a larger percentage return from retail sales. Whatever the reason for self-publishing, authors should know that there is extensive work required in publishing a book alone. Publishing alone involves a long list of tasks, which include prepublication and publication. Prepublication includes editing or obtaining editing for the manuscript, proofreading, establishing yourself as a legal retail business, and obtaining an ISBN “Cataloging in Publication” number. The publication process involves formatting the manuscript, providing front matter and back matter, and providing cover art for the front and back covers and the spine of the book. Self-publishers must also obtain printing quotes, determine how the manuscript will be delivered to the printer, and pay for printing and delivery of finished books. Self-publishing is a business that many writers prefer to avoid, but for others it may be the only way to have the work printed and available to the public. |
