| Name | Uncertainty_System |
|---|---|
| Entity Type | Table |
| Description | A set of values that represents the uncertainty associated with a value or set of values. "Uncertainty" is a characterization of the likely deviation of a measured, derived, or estimated value from its true value. |

NUMBER(38) |
| Existence_Kind | REF_EXISTENCE_KIND | NA |
A reference value that describes the state of existence in the lifecycle of the entity, for example, Planned, Predicted, Required, Simulated, and Actual. | Yes Actual |
VARCHAR2(64) |
| GUID | STRING128 | NA |
Globally Unique IDentifier for an instance of a class. USAGE NOTES: There are two cases: 1) GUID is not populated or used; and 2) it is populated with a value that is globally unique. If the GUID is populated there are two means of doing so for a given project: 2a) Seabed automatically generates and populates the GUID when an instance is created (valid only on Oracle based systems); and 2b) the GUID is generated and populated by an application (other than Seabed) on instance creation. Whether Seabed automatically generates GUIDs for a project is determined by the Auto_GUID flag in SDS_Account. Note that techniques 2a and 2b can coexist in the same project. When GUIDs are automatically generated an application can override the automatically generated GUID with its own GUID by simply supplying the GUID value. Applications that generate their own GUIDs and populate the GUID column will function correctly on projects which have automatic GUID generation turned on. | No |
VARCHAR2(128) |
| Id | ID | No_Unit |
Unique identifier for this entity. | Yes |
NUMBER(38) |
| Insert_Date | DATE | NA |
Date the entity was created in the repository | No |
DATE |
| Insert_User | STRING64 | NA |
The name of the user responsible for the creation of this entity in the repository. | No |
VARCHAR2(64) |
| Name | ENTITY_NAME | NA |
The name given to any object or data item, e.g. name of Well, name of Field, etc. | No |
VARCHAR2(255) |
| Original_Source | STRING64 | NA |
The name of the person, Organization or project source that originally provided this entity, e.g. "IHS-EnergyData" or "FinderUpper Stratton Deeper Pool 15" | No |
VARCHAR2(64) |
| Produced_By | STRING64 | NA |
The name of application role that created the entity, for data created programmatically. | No |
VARCHAR2(64) |
| Refinement_Allowed_Flag | boolean | NA |
If zero or NULL, refinement of Uncertainty_System is disallowed. | No |
NUMBER(1) |
| Remarks | STRING2000 | NA |
Any type of remarks added to an entity instance. | No |
VARCHAR2(2000) |
| Restrict_To_Attribute | STRING32 | NA |
The (name of the) attribute in the entity referenced at Involved_Entity_Type for which this Uncertainty_System object provides type-level uncertainty info. If missing, it applies to all attributes matching the other criteria. | No |
VARCHAR2(32) |
| Restrict_To_Property | R_Property |
|
The name of a Property controlled by this Uncertainty_System. For example, if this value is "permeability", then it is implied that every permeability value in the database has this uncertainty associated with it. If missing, no Property restriction is assumed to apply. Note: The association with Property also provides information about the units of uncertainty, which if meaningful and not inherent to the uncertainty family, are constrained to match the Property Cannonical_Unit. For example, if the uncertainty value applies to everything with a certain Property type, then the parameter value must be in the same unit as the Property unit - if that parameter value is expressed in a unit of measure. | No |
VARCHAR2(64) |
| Restrict_To_Type | Meta_Entity |
|
The entity type name controlled by this Uncertainty_System. If missing, it means that it is a property default common to multiple entity types. | No |
VARCHAR2(30) |
| SDAT_Label | int | No_Unit |
Label used by the security system for entitlements. SDAT is Secure Data Access Technology. | No |
