Service component, method and system for developing application software based on service component

Abstract

The embodiment of the invention discloses a service component, a method and a system for developing application software based on the service component. The method for developing the application software based on the service component comprises the following steps: determining service flow topology corresponding to a function according to the function to be realized by the application software; determining the service component required by the current service flow and connections among service components according to the service flow topology; and after acquiring the service component required by the current service flow, assembling the service component according to the connections to form the application software corresponding to the function to be realized. The method for developing the application software provided by the embodiment of the invention is carried out based on the service component. The service component has service meaning, can directly express a service concept, and meet service requirement of the application software.

Description

technical field [0001] The invention relates to the technical field of software engineering, in particular to a business component and a method and system for developing application software based on the business component. Background technique [0002] In the field of software engineering, a software component is defined as a self-contained, programmable, reusable, language-independent software unit that can be easily used to assemble applications. In view of the easy assembly of software components, the development method based on software components is widely used in the field of software engineering. [0003] Software component-based development is a software development paradigm. With the support of this paradigm, developers of software components and application software can realize industrial division of labor, and developers of software components focus on the development and delivery of software components. , while the developer of the application software realizes...

Problems solved by technology

Different industries have their own industry characteristics, and there are many differences between different businesses in the same industry. Therefore, in the existing technology, when developing application software for a specific industry based on technical components, because the technical components do not It is business-specific, so there are many difficulties. Taking the banking industry as an example, the banking application software system requires business correlation between transactions, and it is difficult to directly express its business meaning with existing technical components; the banking application software system The realization of a business function requires the coupling and association of multiple technical components, which increases the complexity of the combination of technical component development and application systems; the banking application software system developed based on the technical component model is not easy to expand according to business needs after it is put into production , it is difficult to meet the diverse business needs of customers
