Information delivery using queries and changeable database containing queries, advisory information, and flow logic

摘要

A data storage system may contain a changeable database that includes: advisory information that includes the content of multiple advisory statements; query information that includes the content of multiple user queries; and flow logic information indicating a sequence for the delivery of the advisory statements and the user queries based on answers to the user queries. A user interface may deliver the user queries and the advisory statements to a user and receive answers in response to the user queries from the user. An information delivery engine that is separate from the changeable database may cause the user interface to deliver the user queries and the advisory statements to the user in a sequence based on the user's answers to the user queries and the flow logic information. This in system may be adopted to troubleshooting equipment, such as an optical network terminal.
