A Novel Method to Realize the Many-to-Many Mapping in Lifting Appliances' Safety Evaluation
Hong Rao, Xiao Rui Dong, Hong Wu Gong · Advanced materials research · 2012
A code control mechanism (CCM) was proposed in this paper to solve the complex many-to-many mapping problem in lifting appliances safety evaluation, in which, the complicated many-to-many constraints relation is replaced by the character string. The novel method can reduce the redundant data tables and improve the system efficiency. CCM can be extended to realize the object-typed many-to-many mapping in other area.
