description The invention provides a method, a device and a system for data inquiry, which are applicable to the field of data processing. The method includes steps of acquiring relational data flows from a database; reading data from the relational data flows one by one and connecting read data bridges to be an object flow and mapping the object flow to be objects. The method, the device and the system are simple in use since object models, relation models and mapping relations do not need to be built in advance; further, relational data flows in the database are converted into objects so that programmers can program conveniently and convenience and efficiency in data inquiry in the database are improved. Moreover, the data flows can be shut down automatically on the condition of enumeration success or failures, and thereby safety shutting down of connection of the database is guaranteed.
