POSC Specifications: Epicentre Version 3.0 | Relational Implementation |
The characteristic of a permeable strata that describes the tendency to exhibit vertical equilibrium of flowing fluids. This ratio is defined as: (length / height) * SQRT(kv/kh), where length is the characteristic length of the flow path, height is the gross or net height, kv is vertical permeability, and kh is the horizontal permeability (measured on either net or gross pay). The height and kh terms should either both be net or both be gross.
- instance_s (PK, M: CHAR VARYING(19))
- Surrogate key of the table.
- data_value_n (M: FLOAT)
data_value_d (M: FLOAT)
- pty_eff_length_thickness_ratio.data_value
The value of the effective length thickness ratio.
- 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).
- 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.
- core_s (FSK, O: CHAR VARYING(19))
- pty_eff_length_thickness_ratio.core
Defines a foreign key to table bulk_material.
- hole_s (FSK, O: CHAR VARYING(19))
- pty_eff_length_thickness_ratio.hole
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.
- reservoir_s (FSK, O: CHAR VARYING(19))
- pty_eff_length_thickness_ratio.reservoir
Defines a foreign key to table geologic_feature.
- reservoir_part_s (FSK, O: CHAR VARYING(19))
- pty_eff_length_thickness_ratio.reservoir_part
Defines a foreign key to table geologic_feature.
Table is related to: data_collection_content, document_specification_part, @graphical_element, process_data_item, @property
Primary Key Constraint on: INSTANCE_S
