While e-business refers to more strategic focus with an emphasis on the functions that occur using electronic capabilities, e-commerce to be a subset of an overall e-business strategy. E-commerce seeks to add revenue streams using the Worldwide Web or the Internet to build and enhance relationships with clients and partners and to improve efficiency using the Empty Vessel strategy. Often, e-commerce involves the application of knowledge management systems.

E-business involves business processes spanning the entire value chain: electronic purchasing and supply chain management, processing orders electronically, handling customer service, and cooperating with business partners.

using open ended labels called tags.

accessible as a shared vocabulary that is both originated by, and familiar to, its primary users.

Because folksonomies develop in Internet-mediated social environments, users can discover (generally) who created a given folksonomy tag, and see the other tags that this person created. In this way, folksonomy users often discover the tag sets of another user who tends to interpret and tag content in a way that makes sense to them. The result, often, is an immediate and rewarding gain in the user's capacity to find related content. Part of the appeal of folksonomy is its inherent subversiveness: when faced with the choice of the search tools that Web sites provide, folksonomies can be seen as a rejection of the search engine status quo in favor of tools that are created by the community.

Foundation services: These are the core services commonly used to build Web applications, including business integration, collaboration, content management, identity management, and search. These services vary by customer, and may include others. Integration products: These are components that integrate content, application services, and security from existing systems, such as groupware, ERP, and CRM systems. Portal platform: The platform consists of the personalization, administrative, and knowledge management framework that brings together a broad range of electronic resources in different Web experiences. Composite applications: These are Web applications hosted within the portal that combine services from different systems, which the portal orchestrates in custom business processes.

The Internet protocol suite — like many protocol suites — can be viewed as a set of layers. Each layer solves a set of problems involving the transmission of data, and provides a well-defined service to the upper layer protocols based on using services from some lower layers. Upper layers are logically closer to the user and deal with more abstract data, relying on lower layer protocols to translate data into forms that can eventually be physically transmitted.
