Research On User-oriented Business Command Language

With the occurance of Internet Plus,Internet will be closely related with all walks of life.However,due to different background,software developers can't accurately understand specific business requirements during the informationization process sometimes.So the business modeling they construct could not meet the requirements of clients very well.And business modeling is mainly described by business modeling language.But the existing business modeling languages nowadays like BPEL,UML mainly face to computer professionals.To non-computer professionals,these modeling languages are too technical and their threshold for the usage is quite high.Once the business changed,clients have to beg for those computer professionals to modify the model or even reconstruct them to support these changed requirements.This kind of restriction influence the power and development of the business modeling and the normal business at the same time.Base on this,this paper propose an user-oriented business command language called band language.This new modeling language is designed for non-computer professionals,writting in Chineses and its expression is closed to natural language so as to lower the usage threshold for business modeling.In the meantime,the business modeling building on the execution supporting platform of band language have more advantages in flexibility,availability and extensibility.Users can build the model for specific scenario in the band language editor by combining commands supplied by band language together.This paper will introduce the rules of lexical and syntatic of band language as well as the design and implementation of the parse and execution system for band language.
