Abstract

• There are two important classes.
• Class ExtraMaterial build a extra material
  volume.
• ExtraMaterial can build only 3 shapes, Tube,
  TubeSector and Cone for the extra material
  volume.
• The extra material information are detailed in
  Oracle DB.
• Class TubeVolData reads the information from
  the DB and keeps them.
• TubeVolData also selects the shape of the extra
  material volume by rmin1, rmin2, etc

Building Flow
For Example
1) SCT_Layer gives a region name and a volume
named supportLayer as a parent volume to
ExtraMaterial.
SCT_Layer
5) ExtraMaterial builds a extra material as a
child volume of the given parent volume.
ExtraMaterial
2) ExtraMaterial gives a region name
to TubeVolData.
4) ExtraMaterial gets information of a extra
material from TubeVolData.
TubeVolData
3) TubeVolData finds requested information. A key
for this finding is region name. Then it gets
information of a extra material requested by
ExtraMaterial.

Conclusion

• We can modify extra materials via the Oracle DB.
• Who can modify the Oracle DB ?
• Is the modification easy for end users ?
