Abstract
With the rapid development of modern economy and the continuous improvement and
upgrading of information technology, the management of traditional data information
is upgraded to the management mode of software storage, induction and centralized
processing of data information. This online learning and recommendation system was
born in such an environment. It can help managers deal with huge data information in
a short time. Using this software tool can help managers improve transaction
processing efficiency and achieve twice the result with half the effort. This online
learning and recommendation system uses the current mature Python technology and
MySQL database, one of the most popular RDBMS applications, for program
development. Online learning and recommendation system has administrators,
teachers and students. Administrator functions include personal center, subject
management, teacher management, student management, learning resource
management, learning record management, resource evaluation management and
system management. Teachers release learning resources, review students' learning
records, students view learning resources, submit resource evaluation and submit
learning records. The development of online learning and recommendation system is
designed according to the needs of operators. The interface is simple and beautiful,
and the layout of functional modules is consistent with that of similar websites. When
the program realizes the basic required functions, it also provides some practical
solutions for the security problems faced by data information. It can be said that the
program not only helps managers deal with work affairs efficiently, but also realizes
the integration, standardization and automation of data information.
