Just as the use of a graphical interface has changed computing, making it more user-friendly, the use of Adobe Dreamweaver renders people with limited understanding of web construction capable of putting together a quality site. It is also an excellent platform for learning how web sites should be put together. For example, when you create a new page, Dreamweaver lets you choose from a series of standard layouts based on CSS (Cascading Style Sheets), the recommended specification for creating web pages. The code produced by Dreamweaver contains useful comments explaining how the page layout works.

Many small organisations have already learned to rely on Adobe Dreamweaver to build and manage their own website, creating and modifying pages and then uploading them via FTP to make them live and available to the public. Those organisations with a more urgent need to establish a web presence may still turn to a professional web development companies to get them started and then use Adobe Dreamweaver when changes need to be made, often saving themselves a small fortune.

Another way that companies can save a few bucks is by commissioning web designers to create Dreamweaver templates and then using these templates in-house to build the website themselves. This also has the benefit of allowing organizations to maintain control of their site from the outset.

Although Dreamweaver is simple to use, it is unlikely that the average user can simple load it onto their machine and start using it effectively. Most people will benefit from having some Dreamweaver training. This will show them which are the essential aspects of the program and the process of creating a basic site and making it live. A good Dreamweaver training course will also give users an overview of the may web technologies, the underlying code, which Dreamweaver uses as the users visually create their web pages.

One of the best ways to make a site useful for visitors is making it interactive, allowing users to search for the specific content that they want. By attending an advanced Dreamweaver training course, staff within an organization can learn to add database-driven content to their website using technologies such as ASP, PHP or ColdFusion. And, here again, Dreamweaver does the lion’s share of the work, allowing users to create sophisticated search and results pages using the same simply point-and-click and drag-and-drop techniques used to create basic content.

The PDF format is another example of a platform-independent format which has gained worldwide acceptance. Once a document is saved in PDF format, its format is set in stone, it can viewed and printed with its layout and formatting intact, without the need for the software which created the original document. However, where the PDF format concerns itself mainly with the presentation of information, XML is used to describe and encapsulate the information itself.

Though XML itself is still fairly new, the idea behind is over thirty years old. In the 1970s, Standard Generalized Markup Language (SGML) was developed in an attempt to create an application-independent method of describing and storing data. SGML is a text-based language which relies on the concept of adding mark-up to data which describes the data itself. An SGML document contains both the original data and a lexicon of rules defining the structure of that data. SGML is a fairly complex language and, unlike XML, has never gained wide popularity. In the early 1990s, SGML was used to develop and specify the rules of HyperText Markup Language (HTML) and in the late 1990s, SGML was again called upon, this time as the basis for the creation of XML. In a lot of ways XML is basically a restricted form of SGML.

XML has already proved itself an excellent medium for storing, describing and transporting data, particularly over the web. It offers flexibility, clarity and simplicity. An XML document looks similar to an HTML document and consists of the same human-readable tags. However, the tags used to markup an HTML document are pre-defined: only a limited set of tags can legitimately be used. XML allows you to create a markup language and define the tags which are legitimate for your data. It does this using a schema document, which can itself be an XML document. The schema document specifies the vocabulary and grammar which may be used within the XML document which contains your data.

The fact that, when creating and generating XML documents, you can invent all the rules, means that you never have to force your data into a container which was not designed to hold it. You design tags which reflect the nature of your data; you create a schema document which defines the hierarchical structure of your information; and you specify the type of information each element within your document is permitted to contain. In short, if you end up with an XML documents which is unsuitable for holding your information, you have only yourself to blame!
