e-commerce is basically Web client/server middleware, or what is called three-tier architectures. The client tier is the Web browser involving some type of form processing. The middle tier is the Web server, often with transaction processing. The Web server in turn links to the third tier, a database processing the order information. Some of the issues are strictly Internet-related, such as domain names and trademarks, linking and framing, clickware (and shrinkware), and metatag use. Others are traditional issues applied to the Internet, such as copyright, contracts, consumer protection, privacy, taxation, regulated industries and jurisdiction. E-commerce site development, its advertising, electronic transaction, money transactions and such involve many legal issues, which need to be taken into account step by step. Before developing an e-commerce site a registered domain and a registered trademark should be established. There must be some copyright protection on the site. The business must ensure that it displays the terms and condition/policies within its site. Security involving the privacy of a user’s data is always one of the main concerns while doing business online. Defining rules and regulations for the advertisement of the site by placing banners on other known sites is another. It is of great value when dealing with such complex issues to consult an attorney who specializes in the issues of cyberspace.
