Basal base has three components, basal data base, basal knowledge base and media base. Data base has relationship data based on forage disease diagnostic system . Knowledge base is established by disease list. Media base mainly includes the pictures and video data which could be used in accessorial diagnoses. Dynamic base includes dynamic data base and dynamic knowledge base, and has a similar structure to the basal data base and basal knowledge of the basal base.
