<p>The invention concerns a technology for reusing a software component, and presents a method of eliminating dependency of service components on a business entity of a specific application so that binary components independently developed can be reused without modifying source codes. Unlike the conventional methods of developing software by defining a business entity first and then developing service components according to the specification thereof, with the invention, a component developer defines any data type to be used in implementing business logic without consideration for a specific business entity and then develops a service component on the basis of the definition, and an application developer then develops software which coordinates and in- terworks with the data type defined by the component developer and the attribute type of the business entity actually to be used in an application by means of a data type converter when assembling the components developed as such.</p> |
