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)
I_Coordinate int Dimensionless
Representation of the X coordinate of the point in a system other than geographic. For example, a crossline number or CDP number. No
NUMBER(10)
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)
J_Coordinate int Dimensionless
Representation of the Y coordinate of the point in a system other than geographic. For example, an inline number. No
NUMBER(10)
Line_Id Line
The identifier of the line of which the vertices are points. Yes
NUMBER(38)
Line_Segment int Dimensionless
Numeric ID of each segment of a line, in a case where a line needs to be described as composed of segments. The segments need not be connected. No
NUMBER(10)
Name STRING255 NA
Optional name associated with a point along a line. An example would be an alphanumeric shotpoint name on a seismic line. No
VARCHAR2(255)
Position_Id Position
A type of vertex that is located in, on, or above the Earth but is always locatable using a geo-referenced coordinate system. No
NUMBER(38)
Produced_By STRING64 NA
The name of application role that created the entity, for data created programmatically. No
VARCHAR2(64)

Label used by the security system for entitlements. SDAT is Secure Data Access Technology. No
NUMBER(10)
Sequence_Number int No_Unit
Mandatory numeric ID of each vertex of a line, in sequential order. No
NUMBER(10)
Update_Date DATE NA
Date of the most-recent modification to the entity. No
DATE

The name of the user responsible for the last modification to this entity. No
