POSC Specifications: Epicentre Version 3.0 | Relational Implementation |
This entity describes the connection between two wellbore component facilities. It is not necessary to use this entity to describe components connected together to form an assembly, as the parts and assembly list relationship on wellbore component facility can be understood to contain this. Rather this should be used where, for example, two wellbore_component_facilities that are both assemblies are connected together, without one becoming part of the other.
- instance_s (PK, M: CHAR VARYING(19))
- Surrogate key of the table.
- 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).
- connected_with_s (FSK, M: CHAR VARYING(19))
connected_with_t (M: CHAR VARYING(30))
- wellbore_component_fcl_conn.connected_with
This is the other wellbore_component_facility that is connected to the designated wellbore_component_facility. To describe a packer connected to a casing_string, this attribute points to the casing_string.
connected_with_s: Implements a foreign key to a row in one of the tables projected from entity wellbore_component_facility depending on the value of the next column (See below).
connected_with_t: Defines the name of the referenced table. Possible values are defined in @wellbore_component_facility.
- wellbore_component_facility_s (FSK, M: CHAR VARYING(19))
wellbore_component_facility_t (M: CHAR VARYING(30))
- wellbore_component_fcl_conn.wellbore_component_facility
This is the designated wellbore_component_facility that this connection is described for. For example, to describe a packer connected to a casing_string, this attribute points to the packer.
wellbore_component_facility_s: Implements a foreign key to a row in one of the tables projected from entity wellbore_component_facility depending on the value of the next column (See below).
wellbore_component_facility_t: Defines the name of the referenced table. Possible values are defined in @wellbore_component_facility.
- description (O: CHAR VARYING(2000))
- e_and_p_data.description
A remark or comment about the instance.
- duration (O: FLOAT)
duration_u (FNK, O: CHAR VARYING(15))
- transient_association.duration
Defines the duration of the association expressed in any valid units of time.
duration_u: Defines the unit of measure. Defines a foreign key to table r_unit_of_measure.
- end_time (O: TIMESTAMP)
end_time_cd (O: CHAR(1))
end_time_yr (O: FLOAT)
end_time_yp (O: INTEGER)
end_time_dy (O: INTEGER)
end_time_hr (O: INTEGER)
end_time_mt (O: INTEGER)
end_time_st (O: FLOAT)
end_time_of (O: FLOAT)
- transient_association.end_time
End time of the association.
- 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.
- is_current (O: CHAR(1))
- transient_association.is_current
When TRUE, this flag indicates that this instance is designated as a current instance. This flag can be used in place of time based attributes or can be used in conjunction with them; however, it should not conflict with them.
- 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.
- 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".
- start_time (O: TIMESTAMP)
start_time_cd (O: CHAR(1))
start_time_yr (O: FLOAT)
start_time_yp (O: INTEGER)
start_time_dy (O: INTEGER)
start_time_hr (O: INTEGER)
start_time_mt (O: INTEGER)
start_time_st (O: FLOAT)
start_time_of (O: FLOAT)
- transient_association.start_time
Start time of the association.
- caused_by_s (FSK, O: CHAR VARYING(19))
- transient_association.caused_by
Specifies the activity which establishes this association.
Defines a foreign key to table activity.
- kind (FNK, O: CHAR VARYING(80))
- wellbore_component_fcl_conn.kind
The kind or type of wellbore component facility connection. For example, this might be "inside", "outside", "above" or "below".
Defines a foreign key to table r_wellbore_cmpnt_fcl_conn.
- r_transient_period (FNK, O: CHAR VARYING(80))
- transient_association.ref_transient_period
The type of period over which the property applies, such as day, month, quarter, cumulative, etc.
Defines a foreign key to table r_transient_period.
- terminated_by_s (FSK, O: CHAR VARYING(19))
- transient_association.terminated_by
Specifies the activity which established the termination of a transient association between two objects.
Defines a foreign key to table activity.
Table is related to: data_collection_content, document_specification_part, @graphical_element
