Research And Implementation Of Visual Design And Tracking In Zero-code Software Production Platform

E-commerce domain-oriented visual "zero-code" software production platform, called Softproline version 2.0, gained success in large part. For the convenience of user debugging applications, and solving the problem that the system cannot support the interest computing or lack of the effective trace debugging, it is necessary to extend the Softproline and study the visual tracking technology.On the basis of the study of Softproline, the (?) language employed as the reference computing model, combining with the software production practice, the visual design and tracking technology are studied.Based on the programming language (?), the definitions of graph symbol language Lp and engine language Le are proposed, and furthermore, the Lp, the Le languages are extended. For the Lp language, the math function statement, the improved conditional statement, the Web Service access statement, and the exterior service access statement are added. For the Le language, several arithmetic computing statements, several relational computing statements, several logic computing statements, several basic maths function statements, the Web Service access statement, and the exterior service access statement are added. Then, it is proved that the computing ability between the extended Lp and the extended Le language is equal. It is proved that the computing ability between the extended Lp, Le language and Turing is equal. In addition, the computing capability of the extended Lp and Le language has been enhanced.The compiling algorithm translating from the Lp statements to the Le statements is proposed. Most of the Lp statements can be compiled according to defined mapping matrix. The relational DB operation statements and maths function statements of the Lp can be done by proposed compiling algorithm. On the basis of the relation between the Le and Java language, the transformation from the Le to Java is also put forward. Besides, the proposed compiling algorithm is put into the application Softproline V3.0 successfully.Based on the compiling algorithm of the Lp language, the visual tracking with the Lp language level is proposed. The definition of Softproline's trace information is proposed, the representation of trace information is binary array (position information, exceptional information). Then, the transform equations of exceptional information between the Lp, the Le and Java program are defined; based on which the trace information transform method is proposed. Finally, the algorithm, which decides the exception occurring in the scope of input parameters of the Lp relational DB operation and maths function operation, is put forward. Besides, the proposed visual tracking algorithm is applied to Softproline V3.0 successfully.Finally, with several sample examples, this dissertation shows how the study is put into use.
