Design And Implementation Of Personalized Learning Guidance System Based On Data Warehouse

The existing education guidance technology has the disadvantages of poor interaction ability,and the lack of intuitiveness of the guidance results hinders the guidance personnel to improve the guidance results.In order to find out the difficulties and cruxes in the learning process in time,students can quickly improve their learning methods and quickly find weak knowledge points.Based on scientific data,this paper designs a personalized learning guidance system based on data warehouse.Based on the in-depth understanding of personalized learning needs,this paper combines data warehouse technology,Android techno logy,SSH architecture,J2 EE language,and MySQL database technology to design and develop the system.The content includes:(1)The system provides data processing and data source analysis for the learning guidance system by means of data warehouse techno logy,and designs the data structure,data type,data storage,extraction and cleaning process in the data warehouse.The learning guidance system based on data warehouse technology can provide targeted guidance according to the learner's learning characte ristics,and give specific learning problem solutions.(2)According to the system requirements,the system modules are divided into learning data management module,learning test module,academic analysis module,learning guidance module,learning plan mo dule,and job management six modules;and use case analysis of these modules one by one.,design,implementation,and testing.Based on the above modules,the personalized learning effect is detected,and the data learning results are used to guide and pr edict the student's learning situation and teaching methods.(3)Combining the characteristics of massive data and personalized learning analysis generated by personalized learning guidance,the data warehouse model constructed on the basis of personalized learning data is deeply studied.Starting from the demand analysis,the themes of personalized learning analysis are deeply analyzed,and the acquisition process from basic data to intermediate data model is designed and implemented.The multiple dimensions of the data model are deeply designed and analyzed.(4)Carry out research on data cube construction based on personalized learning guidance,and complete the construction of data warehouse instance.Based on the personalized learning guidance data,the data cube construction method is studied.The data warehouse is used to meet the needs of various educational applications for the needs of personalized learning.Through the personalized learning guidance system,the traditional learning aid system is transformed into a simple data management method.The data warehouse technology is combined with the learning guidance system to innovate the function use of the learning guidance system.The scientific and effective learning guidance system is effective.It is of great significance.
