Similarly to Liao (2003), Tyndale (2002) created a taxonomy of KM tools.

1. Intranets. An Intranet is a company-wide information distribution system that uses Internet tools and technology. It could be a simple HTML file linked on a LAN, a full-blown system with dedicated server hardware, or anything in between. Typical Intranet uses are, to give employees access to company documents, distribute software, enable group scheduling, provide an easy front end to company databases, and let individuals and departments publish information the need to communicate with the rest of the company. Typical Intranet content includes, the corporate directory, calendar of events, policies and procedure manuals, and the company newsletter. The most important information will be industry-specific, such as supplier information and databases of products.

2. Web portals. Portals can be seen from several perspectives. "Portal" means "large door" or "gateway", indicating that the portal itself is not the final destination but a way to reach many other places. A Web portal is a web site, usually with little content, providing links to many other sites that can either be accessed directly by clicking on a designated part of a browser screen, or can be found by following an organized sequence of related categories.

3. Content management. Content Management usually includes not only internal web and (or) external web sites but also databases, file servers, and document management system. Because of the increasing load of information, Web Portal or Content Management provides some personalization facilities that are usually set manually by the users. These basically define a set of information categories to which the users want easy access, as well as news or changes in web pages the want to be alerted about.

4. Document management systems. Until recently, document-management systems were designed around expensive, highly functional client software reserved for critical, high-return applications. But with the advent of the Internet, document management can be deployed more easily and more affordably. Now, in addition to traditional client/server systems, document management can include browser-based clients, for users who might need only basic function. These systems are primarily used in the collection, storage, and distribution of the artefacts of knowledge contained in an organization. Many of these systems emulated the paper and library systems. Advanced features of document management systems provide version control, authentication, and translation.

5. Information retrieval engines. Information retrieval engines are used for indexing, searching, and recalling data, particularly text or other unstructured forms. Finding documents, or the information contained in a library or other collection, selectively recalling recorded information. Methods of retrieval vary from a simple index or catalogue to the documents, to a computer-based system.

6. Relational and object databases. A database is a store of information. The data are stored in table and categorized by fields. Each group of information is a record. Relational databases are designed to build links or relationships between two or more different tables of information. The relational model is one of the most successful and widely used, but for complex corporate applications there may be more suitable approaches. Object database management system' (ODBMS') offer simpler solutions to applications that involve objects and the relationships among them. Now, with native database support for new types of data such as spatial, audio and video, and improvements that make it faster to get new ODBMS applications up and running, ODBMS' are becoming even morevaluable to the enterprise.

7. Electronic publishing systems. Electronic Publishing is the distribution of information and entertainment in digital format, usually including software that allows users to interact with text and images. Most forms of information can be published electronically, but users normally require a personal computer and sometimes a connection to a network or the Internet to access the information. The advent of graphical user interfaces (GUIs) in the late 1980s made electronically published information much more marketable than it had been previously. This, along with more widespread availability of CD-ROM drives and intense interest in the potential of the Internet, has turned electronic publishing into a mass-market industry after years of being limited to specialist information.8. Groupware and workflow systems

8. Groupware is a technology designed to facilitate the work of groups. This technology may be used to communicate, cooperate, coordinate, solve problems, compete, or negotiate. While traditional technologies like the telephone qualify as groupware, the term is ordinarily used to refer to a specific class of technologies relying on modern computer networks, such as email, newsgroups, videophones, or chat. The general definition of workflow according to the workflow management coalition (WfMC) is: "The computerized facilitation or automation of a business process, in whole or part". Workflow technology allows an organization to automate its business processes to better manage those processes, and therefore better manage their outcomes, be they products or services. Workflow technology will deliver work items (things to do) to appropriate users, and help the users by invoking appropriate applications and utilities (know to accomplish the task). Further, it will allow management and employees to track the progress of the work item through the process and generate statistics on how well the different steps of the process are doing.
