Integrity of Modifications
The engineering integrity is always maintained for any database modification.
The integrity checks are applied below the database interface. Thus modifying the database is always safe whether done via PML commands or C#.
The checks are applied to individual attributes and element types. For example the OBST attribute can only ever be set to 0,1 or 2. AVEVA E3D™ will always check that this is the case prior to allowing the modification.
