POSC Specifications: Epicentre Version 3.0 | Relational Implementation |
A point in geologic time, measured in thousands, millions, or billions of years.
- 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_geologic_age.data_value
Time expressed in years, millions of years, or billions of years.
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).
- age_uncertainty (O: FLOAT)
age_uncertainty_u (FNK, O: CHAR VARYING(15))
- pty_geologic_age.age_uncertainty
This is the uncertainty of the geologic age expressed in years, millions of years, or billions of years.
age_uncertainty_u: Defines the unit of measure. Defines a foreign key to table r_unit_of_measure.
- 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.
- feature_boundary_s (FSK, O: CHAR VARYING(19))
- pty_geologic_age.feature_boundary
Defines a foreign key to table geologic_feature.
- geologic_process_s (FSK, O: CHAR VARYING(19))
- pty_geologic_age.geologic_process
Defines a foreign key to table geologic_process.
- interpreted_feature_s (FSK, O: CHAR VARYING(19))
interpreted_feature_t (O: CHAR VARYING(30))
- pty_geologic_age.interpreted_feature
interpreted_feature_s: Implements a foreign key to a row in one of the tables projected from entity interpreted_feature depending on the value of the next column (See below).
interpreted_feature_t: Defines the name of the referenced table. Possible values are: seismic_pick, wellbore_pick (@interpreted_feature).
- 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.
- reservoir_fluid_system_s (FSK, O: CHAR VARYING(19))
- pty_geologic_age.reservoir_fluid_system
Defines a foreign key to table bulk_material.
- rock_feature_s (FSK, O: CHAR VARYING(19))
- pty_geologic_age.rock_feature
Defines a foreign key to table geologic_feature.
- rock_fluid_feature_s (FSK, O: CHAR VARYING(19))
- pty_geologic_age.rock_fluid_feature
Defines a foreign key to table geologic_feature.
- rock_material_s (FSK, O: CHAR VARYING(19))
- pty_geologic_age.rock_material
Defines a foreign key to table bulk_material.
- temporal_event_s (FSK, O: CHAR VARYING(19))
- pty_geologic_age.temporal_event
Defines a foreign key to table temporal_event.
Table is related to: data_collection_content, document_specification_part, @graphical_element, process_data_item, @property
