Different knowledge management systems are:-

• CMIS (Capacity Management information system) – A Capacity Management Information System or CMIS is a collection of IT INFRASTRUCTURE usage, capacity and performance information that is gathered in a consistent manner and stored in one or more databases. It is a single book of record for all usage, capacity, and performance data, complete with associated business, application and service statistics. Any IT staffer who NEEDS access to capacity management data can potentially use a CMIS.
• AMIS (Availability management information system) – A virtual repository of all Availability Management data, usually stored in multiple physical locations.
• KEDB (Known error database) – A Known Error is a problem that has a documented root cause and a Work around. Known Errors are managed throughout their lifecycle by the Problem Management process. The details of each Known Error are recorded in a Known Error Record stored in the Known Error Database (KEDB).
• CMDB (Configuration management database)– A configuration management database (CMDB) is a database that contains all relevant information about the components of the information system used in an organization’s IT services and the relationships between those components. A CMDB provides an organized view of data and a means of examining that data from any desired perspective. Within this context, components of an information system are referred to as configuration items (CI). A CI can be any conceivable IT component, including software, hardware, documentation, and personnel as well as any COMBINATION of them. The processes of configuration management specify, control, and track configuration items and any changes made to them in a comprehensive and systematic fashion.
• DML (Definitive media library)– A Definitive Media Library (DML) is a secure COMPOUND in which the definitive, authorized VERSIONS of software package configuration items (CIs) are stored and protected. A DML consists of one or more software libraries or file-storage areas referred to as repositories.
• SKMS (Service knowledge management system) – ITIL Knowledge Management aims at gathering, analyzing, storing and sharing knowledge and information within an organization. The primary purpose of Knowledge Management is to improve efficiency by reducing the need to rediscover knowledge
