Abstract: Information systems should flexibly and quickly adapt to variable requirements. An information system implementation method was proposed that only modifying the business rule can achieve information systems adaptability. Based on a steady business pool consisting of business granules and business objects, variable factors on the business object aggregate business granule operates were separated from information systems codes and stored as the business rule, which was implemented through the corresponding business rule engines. Therefore, information systems based on this method can flexibly and quickly adapt to variable requirements through configuring the business rule. Experiments and examples were provided to evaluate the feasibility of the proposed method.

Key words: business rule, adaptability, information system
