Research On Database Processing Scheme Of Apla-python Program Automatic Generation System In Par Platform

With the development of computer technology,we have entered the information age comprehensively.Nowadays,the application of database technology has penetrated into various industries,and the types of data stored are also different due to different needs,such as ordinary text data,picture data,video data,etc.,thus it can be seen that the use of traditional database has been unable to meet the needs of people in daily life.In order to effectively solve these problems,professor xue jinyun proposed a software development platform called PAR method.The database program generation module of the platform can not only process the basic structured data,but also add a processing mechanism for the unstructured data(multimedia data).PAR method and PAR platform is a new software development method proposed by xue jinyun's team to realize algorithm design and proof.It supports custom types and can automatically generate and run generic programs,database programs and interface designer programs.PAR platform of database generating system,describe the database in the form of relational algebra corresponding management and operation,makes the database generation system is guarantee and PAR method in the reliability and validity of the description of the mechanism of relational database and implementation guidelines based on PAR method,by making a reliable database component library,making it easier for the database application development theory support,optimization and validation,and implements the part of the automatic generation of database application code,so as to achieve the rapid development of the purpose of accurate and reliable database applications.Based on the automatic generation system of Apla-Python database program in PAR platform,this paper takes Oracle database as background database management system(DBMS),formulates corresponding part library and operation method according to the processing statement of multimedia data in Oracle database,and expands Apla language rules.In Apla,relational algebra is used to describe multimedia data management and operation,which makes the development of multimedia data applications theoretically supported,optimized and verified.Finally,a test case is used to test the Apla-Python database program generation system,which proves that the research work has basically achieved the expected goal,which is of great significance and practical value to the development of PAR platform.The main innovation points of this paper are:(1)realized the development of Python module of database generation system in PAR platform;(2)on the basis of the original system,the management and operation mechanism of the alpa-python database program automatic generation system for multimedia data was added;...
