1000 General objective or purpose of a seismic survey

We need to indicate, in the same way that we do for a well, what is the general purpose of the seismic survey. For the present time we plan to extend Epicentre making a new relation-attribute to SEISMIC GEOMETRY SET : seismic survey purpose.

Add new entities and relationships

Add new entities Seismic_geometry_classification and Seismic_geometry_class with many-to-one relationships from Seismic_geometry_classification to Seismic_geometry_class and Seismic_geometry_set. This will allow a survey to be classified based on a classification system of "seismic survey purpose".

Added objects:
seismic_geometry_set.seismic_geometry_classification (Attribute)
seismic_geometry_classification (Entity)
seismic_geometry_class (Entity)

Modify diagram.

Modify diagram GPA1 to add entities Seismic_geometry_classification and Seismic_geometry_class.
