Ecommerce definition and types of ecommerce
Ecommerce (e-commerce) or electronic commerce, a subset of ebusiness, is the purchasing, selling, and exchanging of goods and services over computer networks (such as the Internet) through which transactions or terms of sale are performed electronically. Contrary to popular belief, ecommerce is not just on the Web. In fact, ecommerce was alive and well in business to business transactions before the Web back in the 70s via EDI (Electronic Data Interchange) through VANs (Value-Added Networks). Ecommerce can be broken into four main categories: B2B, B2C, C2B, and C2C.
- B2B (Business-to-Business)
Companies doing business with each other such as manufacturers selling to distributors and wholesalers selling to retailers. Pricing is based on quantity of order and is often negotiable.
- B2C (Business-to-Consumer)
Businesses selling to the general public typically through catalogs utilizing shopping cart software. By dollar volume, B2B takes the prize, however B2C is really what the average Joe has in mind with regards to ecommerce as a whole.
Having a hard time finding a book? Need to purchase a custom, high-end computer system? How about a first class, all-inclusive trip to a tropical island? With the advent ecommerce, all three things can be purchased literally in minutes without human interaction. Oh how far we've come!
- C2B (Consumer-to-Business)
A consumer posts his project with a set budget online and within hours companies review the consumer's requirements and bid on the project. The consumer reviews the bids and selects the company that will complete the project. Elance empowers consumers around the world by providing the meeting ground and platform for such transactions.
- C2C (Consumer-to-Consumer)
There are many sites offering free classifieds, auctions, and forums where individuals can buy and sell thanks to online payment systems like PayPal where people can send and receive money online with ease. eBay's auction service is a great example of where person-to-person transactions take place everyday since 1995.
G2G (Government-to-Government), G2E (Government-to-Employee), G2B (Government-to-Business), B2G (Business-to-Government), G2C (Government-to-Citizen), C2G (Citizen-to-Government) are other forms of ecommerce that involve transactions with the government--from procurement to filing taxes to business registrations to renewing licenses. There are other categories of ecommerce out there, but they tend to be superfluous.

satellite
Any object, man-made or natural, that orbits another body.
In astronomy, a satellite is a natural body that revolves around a planet and is also called a moon. With the IAU's 2006 decision on the definition of a planet (which changed the definition of Pluto), a satellite (moon) can also revolve around a dwarf planet, as Charon does for Pluto.
In aerospace and space exploration, a satellite is a man-made object launched into space to orbit the Earth, moon, sun or other celestial body. Some examples are weather satellites and communications satellites.
Advantages of Information Technology:
To understand the importance of Information Technology, it is very important to know the advantages of using IT applications.

Different Types of Information Systems
Different Types of Information Systems
As can be seen in the pyramid there are a lot of different information systems. A lot of information systems combine different types. They all have different purposes and because they can be confusing, knowledge of information science is essential to make an information system succesful.

Executive Information System
An Executive Information System (EIS) is a type of management information system intended to facilitate and support the information and decision-making needs of senior executives by providing easy access to both internal and external information relevant to meeting the strategic goals of the organization. It is commonly considered as a specialized form of a Decision Support System (DSS).
Decision Support Systems
Decision Support Systems (DSS) are a specific class of computerized information systems that supports business and organizational decision-making activities. A properly-designed DSS is an interactive software-based system intended to help decision makers compile useful information from raw data, documents, personal knowledge, and/or business models to identify and solve problems and make decisions.
Management Reporting Systems
Management Reporting Systems are intended to provide aggregated data about the performance of the organization. Usually these are created from data generated by the knowledge or operational layers of information systems
Business Intelligence Systems
Business Intelligence (BI) refers to skills, technologies, applications and practices used to help a business acquire a better understanding of its commercial context. Business intelligence may also refer to the collected information itself.
BI technologies provide historical, current, and predictive views of business operations. Common functions of business intelligence technologies are reporting, OLAP, analytics, data mining, business performance management, benchmarks, text mining, and predictive analytics.
Popular closed source (e.g. Business Objects (SAP) or Cognos) and open source (e.g. JasperSoft or Pentaho) software often have the functionality that can provide information for the different types of information systems that are shown in the pyramid.
Office Information Systems
Office Information Systems provide information to the organization that is not directly available from operational support systems. Often this is textual data(e.g. Office-documents or E-mail), but it can also be a CRM (Customer Relationship Management) system. Intranet and wiki's are very popular applications of these.
Knowledge Management Systems
Knowledge Management Systems are meant to facilitate knowledge management in an organization. As described in our approach and in the knowledge creation cycle they are only part (although very important) of a knowledge management strategy. It is not an Office Information System as is often thought and should be smaller in size than Office Information System. If implemented and used properly they can be considered as force multipliers for an organization.
Transaction Processing Systems
A Transaction Processing System is a set of information which process the data transaction in database system that monitors transaction programs (a special kind of program). The essence of a transaction program is that it manages data that must be left in a consistent state. These are usually databases.
