A knowledge database is a database that is used to share and manage knowledge. It encourages knowledge accumulation, organization, and retrieval. Many knowledge bases are built on artificial intelligence, allowing them to store data and solve problems using data from previous experiences recorded in the knowledge base. Data management technologies, varying from relational databases to data warehouses, are used in knowledge management systems. Some knowledge bases are nothing more than indexed encyclopedic information, while others are interactive and respond to the user's input. A knowledge database is more than just a place to store data; it can also be used to make intelligent judgments using artificial intelligence.
