Amongst other things, some of the advantages that the development s in ASP.NET hold over its predecessor include:
- User-defined controls allow commonly used templates, such as menus.
- An extensive set of controls and class libraries allows the rapid building of applications.
- ASP.NET leverages the multi-language capabilities of the .NET Common Language Runtime, allowing web pages to be coded in VB.NET, C#, J#, etc.
- Ability to use the "code-behind" development model to separate business logic from presentation.
SQL (Structured Query Language) is the most popular computer language used to create, modify, retrieve and manipulate data from relational database management systems. It was developed by a group at IBM's San Jose research centre, and is today recognised as an ANSI/ISO standard. SQL is designed for a specific, limited purpose - querying data contained in a relational database. This makes it a very powerful tool for web applications in that large amounts of customer or product data can be stored, categorised and quickly retrieved as necessary.
JavaScript is the name of Netscape Communication Corporation's implementation of a programming language based on the concept of prototypes. The language is most commonly known for its use in websites, but can also used to enable scripting access to objects embedded in other applications. JavaScript's syntax is loosely based on C, and shares its likeness of not having any input or output constructs of its own. A JavaScript engine relies on the host environment into which it is embedded, of which web technologies are the most widely known examples. One major use of web-based JavaScript is to write functions that are embedded in or included from HTML pages and interact with the Document Object Model of the page to perform tasks not possible in HTML alone. Some common examples of this usage are given below:
- Opening or popping up a new window with control over the size, position and style of the new window (i.e. whether or not the menus, toolbars, etc. are visible; usually JavaScript is used to ensure that they are not).
- Checking or validating web form input values to ensure they will be accepted before they are submitted to the server.
- Changing images as the mouse cursor moves over them. This effect is still enjoyed by many designers, often to draw the user's attention to important links displayed as graphical elements.
It is in the hands of your chosen web developer to find the much needed synergy between design and functionality, and how to achieve this through the use of the latest technology. Your developer should take the time to understand the needs of your organisation and provide you with the best way forward, whether it be for a simple brochure style web site, or a more sophisticated database driven solution. A website should be seen as more than just a collection of words or images. It has the potential to be a powerful medium for portraying your products and services in the most effective way possible.
