Abstract: In a data parsing method, a data adapter receives a piece of reference data, wherein the reference data has a data structure, the data structure includes at least one tag and a value corresponding to each of the at least one tag, and the reference data corresponds to a topic. The data adapter establishes a schema for the topic according to at least one path related to at least a portion of the at least one tag and the at least one value of the data structure. Referring to the schema, the data adapter uses a parser to parse a piece of objective data into a piece of parsed data, wherein the objective data has the data structure and corresponds to the topic.
