  1. Technologies of e-commerce

  2. Hardware and Software As with all computer systems, e-commerce consists of a collaboration of hardware and software. The software of both the web developer and the user need to be considered.

  3. A web server holds the live copy of the web page which can be seen by anyone who has access to the Internet. • Browsers are installed on a user’s computer and convert the data received via the modem into a visual web page. Internet explorer, Mozilla FireFox, Opera.

  4. A browser is the software that allows the user to view the web page. A cache is a store on a computer hard drive of all the web resources visited by the user. If the user accesses a cached page which has not been updated since the last download, the cached version will be displayed.

  5. Server Software • There are several web server software applications, such as Internet Information Services (IIS), which comes with modern versions of the Windows operating system and Apache HTTP server. • FTP (File Transfer Protocol) makes uploading web pages to the web much easier. CuteFTP has been designed to make uploading more user friendly.

  6. Web authoring tools • All web authoring tools provide the basic facilities to create a web page and upload it to a web server. • Microsoft Frontpage is a good beginner design tool, however the current industry standard is Adobe Dreamweaver because it has a huge range of tools for web design: Flash animation, templates, CSS.

  7. Task Creating web pages is no longer the domain of skilled designers. Anyone can create a web page and upload it. Consequently the quality of the Internet has come into question. One suggestion has been to clean up the Internet. • What is Web 2.0 or www2.? • Do you think the Internet needs cleaning up?

  8. Database Systems • E-commerce sites usually have a database back end storing the catalogue of products, customer records and other business information. This should link to the website seamlessly so the user is unaware of it. • Applications such as Oracle or languages such as MySQL can be used to create the database.

  9. Programming requirements • Web pages are written in HTML Within the HTML code, other languages can be used, including PHP, ASP, Javascript and others which assist functionality. HTML itself does not provide e-commerce capabilities, so another language must always be used as well.

  10. What do they mean? • MySQL is a language for creating online databases. It uses an SQL base, which is the language behind most databases. • HTML stands for Hyper Text Mark Up Language. All web pages are controlled and structured using HTML. • Javascript provides interactivity between the computer and the user. • ASP and PHP allow web pages to connect with databases and online payment systems.

  11. Storage size • The computer acting as the web server needs a large storage area for all the database records, images and other items of the website. • This data is dynamic and if the business is a success, it is likely to grow exponentially.

  12. Portability. • Mobile internet browsing is also available through technology such as mobile phones using WAP. This needs to be taken into account when designing a website. Phone screens are at a reduced size and some still monochrome. Websites need to be written in or dynamically converted to WML (Wireless MarkUp Language)

  13. What does it mean? • A static website is one with no interactivity and is usually just a presentation of information. • A dynamic website can involve any level of interactivity from a simple feedback form to a database which personalises the website for each user. • WAP stands for Wireless Application Protocol • WML stands for Wireless Mark Up Language.

  14. Download Speeds • A variety of download speeds are available and a business should never assume that all customers will have the same connection. • Internet speed is measured in Kilobits persecond (Kbps).

  15. There are several ways of minimising the download times of a website. Images are essential but then they must be small so that loading times are reduced. ==Compression and ALT function== Animations can bring a website to life but they take up a lot of bandwidth so use sparingly.

  16. Browser and platform compatibility Different web browsers interpret code differently and this needs to be taken into consideration when designing web pages. Both old and new computer platforms should also be considered. Web developers should design to meet the lowest specifications otherwise potential customers may be excluded from purchasing products and profit will be lost.
