The invention discloses a system and a method for driving business logic through data changes. The system comprises a logic designing unit, a logic compiling unit, a data change capturing unit and a logic executing unit, wherein the logic designing unit is used for acquiring business logic metadata and outputting the business logic metadata to the logic compiling unit when a user inputs business logic; the logic compiling unit is used for compiling the business logic metadata into the data in the specific program language, further compiling the data into binary business logic program segmentsand then outputting the binary business logic program segments to the logic executing unit; the data change capturing unit is used for calling the logic executing unit according to data change eventstriggered by the data changes; and the logic executing unit is used for directly calling the binary business logic program segments and executing the business logic. Accordingly, the invention can flexibly add and modify the business logic which is not limited to numerical operations but capable of processing the field status and the logic whether a button is available, so as to seek the uniform scheme to handle various business logic types, compile the business logic into binary codes and execute the business logic, thus improving the efficiency.
