基于NoSQL的PDM版本管理
Version Management of PDM Based on NoSQL
摘要
Abstract
The complex product design will produce a large amount of intermediate version,and the version of the model is the basis of version management. Product Data Management ( PDM) system depends on version management,which makes sure that the design per-sonnel can access to the product version of history at any time. And back to the design process,to ensure that products in the stages of life cycle data is correct. As analyzing the shortage of existing version management model of PDM,a new version model of the hierarchical structure is proposed,which can reflect the relationship between the version and the version history clearly and intuitively and make up for the disadvantages of version model. With the increasing of version number,product data stored in PDM shows the characteristics of big data,making the RDB incapable on data processing. So the version model based on hierarchical structure is constructed with NoSQL as the underlying database,taking the advantages of NoSQL to improve the version management. According to the characteristics of the mod-el,the version management functions like version tracking,version merging and effective version control are realized.关键词
