The Design Data module enables the user to store and retrieve all relevant tank data. Featuring visually supported data entry forms, the module assists users in navigating through specific tanks and their components in order to describe the tank in all its details. All changes made to tank data can easily be traced, since the name of the user and the date and time of all modifications are automatically stored by the system. Finally, an inbuilt approval procedure ensures the quality and correctness of all loaded design data.
