POSC Specifications: Epicentre Version 3.0 | Relational Implementation |
The tangential shearing force (in excess of the yield point value) required to induce a unit rate of shear. It assumes that the material obeys the Bingham law of plastic flow. A Newtonian fluid has a yield point value of zero. If a Fann viscometer is used then this could be quoted, in units of centipoise (cP), as the 600 rpm reading - 300 rpm reading.
- 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).
- data_value_sl (O: CHAR VARYING(16))
- pty_plastic_viscosity.data_value
The reported value of plastic viscosity.
- 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.
- 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.
- well_operation_fluid_s (FSK, O: CHAR VARYING(19))
- pty_plastic_viscosity.well_operation_fluid
Defines a foreign key to table bulk_material.
Table is related to: data_collection_content, document_specification_part, @graphical_element, process_data_item, @property
Primary Key Constraint on: INSTANCE_S
