One development thrust of the software industry is to constantly improve the basic elements used to construct software, that is, the so-called programming model.

One development thrust of the software industry is to constantly improve the basic elements used to construct software, that is, the so-called programming model:

L low-level language stage: Assembly commands;

L advanced language stage: advanced language statements and functions (process-oriented programming model)

L object-oriented stage: advanced language statements, functions, and objects (Object-Oriented Programming Model and component-Oriented Programming Model)

L basic framework stage: advanced language statements, functions; objects; basic services (WCF, WWF); (Service-Oriented Programming Model, framework-based programming model)

L domain framework stage: advanced language statements, functions; objects; basic services (WCF, WWF); domain languages and domain services; (domain-Oriented Programming Model)

L next-generation programming model:

By continuously improving Reusable Software ConstructionCodeComponent level to improve the software development rate, so to improve efficiency, it is necessary to increase the level of reusable code components used to construct software.
