MDB (Multiple Database) is a collection of databases assigned to users for accessing and modifying project information.
A project is a collection of engineering databases, catalogues, specifications, drawings, and design information for a plant.
It stores all 3D model information including equipment, piping, structures, and supports.
It contains standard components such as valves, fittings, flanges, steel sections, and equipment templates.
The specification database defines which catalogue components are allowed for a particular piping class.
- World
- Site
- Zone
- Equipment/Structure/Pipe
- Components
The World is the top-most element of the project hierarchy.
A Site represents a physical plant location.
