Abstract
In BIM for Infrastructure, a 3D product model of the bridge includes huge data which is created in its whole lifecycle. In order to share such a huge model between stakeholders and to use it efficiently, it should be managed by some DBMS (DataBase Management System). Relational DBMS is commonly used as an engine by many database systems, but we thought that the DBMS can't efficiently manage the model which is constructed with deep level structure. And we researched performance characteristics of several kinds of DBMS in which the model is stored. Finally we cleared which DBMS can efficiently manage 3D product models of the bridge.
