ecommerce Website Implementation - Glossary
Electronic commerce, commonly known as e-commerce or eCommerce, consists of the buying and selling of products or services over electronic systems such as the Internet and other computer networks. The amount of trade conducted electronically has grown extraordinarily with widespread Internet usage. The use of commerce is conducted in this way, spurring and drawing on innovations in electronic funds transfer, supply chain management, Internet marketing, online transaction processing and automated data collection systems.
Modern electronic commerce uses the World Wide Web at least at some point in the transaction's lifecycle, although it can encompass a wider range of technologies such as e-mail as well.
Network Security Essentials

- Services and options that most e-commerce customers expect. These include shopping carts, free email, stock quotes, and simultaneous help desk support.
- Asymmetric encryption
- Encryption that creates a public key and a private key. The private key remains secret, on your computer. You can freely disseminate the public key.
- Establishes a person's identity.
- The amount of data received over a period of time.

- Browser compatibility
- When creating a Web site, you must make sure that the site is available to users in your target market. Sometimes, this
requires making the site's presentation as generic as possible. In other markets, you may find that specializing in the latest technologies is
the only way to attract users.

- Cookies are small variables that store data about the current user. Cookies are set by the Web server, and are subsequently sent by the client browser with each request that matches the domain and path attributes (if set) set for the cookie. Unless explicitly set to
persist via the Expires cookie attribute, a cookie will be destroyed when the user closes their browser. Cookies may be used to track and store
information such as user name, user password and what parts of the site were visited.

- Checking up on the currency of the site to make sure it looks current and professional.
- Digital cash
- The use of proprietary software to convert "real" money into information easily transferred over a public network.
- Digital certificate
- A way to prove your identity. You can use it to encrypt and decrypt messages from individuals and servers. In technical terms, it is a public key that has been signed by a certificate authority.
- Digital certificates
- The use of one-way and asymmetric encryption to authenticate code or email.
- Digital signature
- Use of a one-way hash algorithm and a private key to provide a stamp of approval on an electronic document or network transmission.
- Digital signatures
- The use of one-way and asymmetric encryption to create signatures on transactions.
- Conducting business on-line.
- Encryption is the process of transforming a file using a mathematical function or technique so that the contents of the file
are protected from unwanted viewing.
Enterprise resource planning
ERP (enterprise resource planning) is the practice of using client/server technology, mainframes, and relational databases to manage all aspects of a business. As the name suggests, it involves planning the business,
but it also covers ways to manage the manufacturing process, make purchases, as well as manage the important parts of its business, including project planning, human resource planning, supply chain management, inventory management, and order tracking.
ERP is designed to lower supply chain costs, reduce the need for large amounts of inventory and enable a manager to conduct real-time checks of his/her company's manufacturing and business processes.
The most popular ERP suite of programs is sold by a German company named Systems, Applications and Products in Data Processing (SAP). Its latest product, the R/3 series, traditionally worked with mainframes,
but is now heavily involved in the client/server model, including Linux.
- The ability to obtain extra information from visitors through the use of reverse DNS lookup and cookies.
