| 摘 要： | In the engineering database system，multiple versions of a design including engineering drawings should be managed efficiently. The paper proposes an efficient spatial data structure，that is an expansion of the R-tree and HR-tree，for version management of engineering drawings. A novel mechanism to manage the difference between drawings is introduced to the HR-tree to eliminate redundant duplications and to reduce the amount of storage required for the data structurr. Data management mechanism and structural properties of our data structure called the MVR+-tree are described.
