KM Architecture has seven layers in it as depicted in the diagram below. Each layer has been discussed in the following few paragraphs.
The User Interface (Layer 1)
User interface design focuses on consistency, relevancy, visual clarity, navigation, and usability.
Authorized Access Control (Layer 2)
Collaborative Intelligence and Filtering (Layer 3)
Personalized views based on stored knowledge
Groupware to facilitate both sync- and asynchronous interaction and discussion
Intelligent agents reduce search time for needed information
Knowledge-Enabling Application (Layer 4):
Referred to as value-added layer
Creates a competitive edge for the learning organization
Provides knowledge bases, discussion databases, automation tools, etc.
Ultimate goal: show how knowledge sharing could improve the employees
Transport Layer (Layer 5)
Most technical layer to implement
Includes LANs, WANs, intranets, extranets, and the Internet
Ensures that the company will become a network of relationships
Considers multimedia, URLs, graphics, connectivity speeds, and bandwidths
Middleware (Layer 6)
Focus on interfacing with legacy systems and programs residing on other platforms
Designer should address databases and applications with which KM system interfaces
Makes it possible to connect between old and new data formats
Physical Repositories (Layer 7)
Bottom layer in the KM architecture
Represents the physical layer where repositories are installed
Includes intelligent data warehouses, legacy applications, operational databases, and special applications for security and traffic management.
