POSC Specifications: Epicentre Version 3.0 | Relational Implementation |
The angle measured clockwise from a reference north direction (magnetic, true, local grid) to an arbitrary line of interest in the plane tangent to the surface of the earth at the point of interest.
- instance_s (PK, M: CHAR VARYING(19))
- Surrogate key of the table.
- data_value (M: FLOAT)
data_value_u (FNK, M: CHAR VARYING(15))
- pty_azimuth.data_value
The angular offset from the specified north direction.
data_value_u: Defines the unit of measure. Defines a foreign key to table r_unit_of_measure.
- instance_create_date (O: TIMESTAMP)
- e_and_p_data.instance_create_date
This is the date that this instance was created. This date is defined by the source if imported, or is the date the instance is created if a new instance.
- last_updated (O: TIMESTAMP)
- e_and_p_data.last_updated
This is the date that this instance was last updated. This value should be updated when any part of this instance is altered (except for inverse relationships).
- r_north_axis_direction (FNK, M: CHAR VARYING(80))
- pty_azimuth.ref_north_axis_direction
The direction from which the angular offset is measured.
Defines a foreign key to table r_north_axis_direction.
- entity_type_nm (M: CHAR VARYING(30))
- Column that contains the name of the entity that this row is an instance of in case a table represents multiple entities. Possible values are: pty_azimuth, pty_dip_azimuth, pty_strike.
- description (O: CHAR VARYING(2000))
- e_and_p_data.description
A remark or comment about the instance.
- instance_creator (O: CHAR VARYING(80))
- e_and_p_data.instance_creator
This is the person, company or application that created this instance. This identifies the party responsible for loading this instance.
- last_updated_by (O: CHAR VARYING(80))
- e_and_p_data.last_updated_by
This records the person or application making the update to this instance.
- preferred_flag (O: CHAR(1))
- property.preferred_flag
The flag is set to True if this instance of property is the preferred value in this data store of this type of property for the object which this property describes.
- source (O: CHAR VARYING(80))
- e_and_p_data.source
The provider of this instance, which is usually a data provider for imported/purchased data. If this instance is provided by POSC, then this attribute must be "POSC".
- activity_s (FSK, O: CHAR VARYING(19))
- process_data.activity
Defines the activity which created this instance.
Defines a foreign key to table activity.
- borehole_trajectory_section_s (FSK, O: CHAR VARYING(19))
- pty_azimuth.borehole_trajectory_section
This is the section of a borehole that this azimuth describes.
Defines a foreign key to table borehole_component.
- edge_s (FSK, O: CHAR VARYING(19))
- pty_azimuth.edge
Defines a foreign key to table spatial_object.
- face_s (FSK, O: CHAR VARYING(19))
- pty_azimuth.face
Defines a foreign key to table spatial_object.
- fracture_s (FSK, O: CHAR VARYING(19))
- pty_azimuth.fracture
Defines a foreign key to table bulk_material.
- represent_s (FSK, O: CHAR VARYING(19))
represent_t (O: CHAR VARYING(30))
- property.represent
This is the property that is the original for which this representation is an equivalent representation.
represent_s: Implements a foreign key to a row in one of the tables projected from entity property depending on the value of the next column (See below).
represent_t: Defines the name of the referenced table. Possible values are defined in @property.
- vertex_s (FSK, O: CHAR VARYING(19))
- pty_azimuth.vertex
Defines a foreign key to table spatial_object.
Table is related to: data_collection_content, document_specification_part, @graphical_element, process_data_item, @property
Primary Key Constraint on: INSTANCE_S
