NUMBER |
| 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) |
| Generation_Date | DATE | NA |
Date of histogram generation | No |
DATE |
| Histogram_Data | BLOB | NA |
Holds the array data of histogram | No |
BLOB |
| Histogram_End_Time | double | Short_Time ms |
End time of the histogram | No |
NUMBER |
| Histogram_Maximum | long | No_Unit |
Maximum number of points of the histogram. | No |
NUMBER(19) |
| Histogram_Sample_Interval | double | Short_Time ms |
Sample interval time | No |
NUMBER |
| Histogram_Size | int | No_Unit |
The number of values in the histogram. | No |
NUMBER(10) |
| Histogram_Start_Time | double | Short_Time ms |
Start time of the histogram | No |
NUMBER |
| 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) |
| Produced_By | STRING64 | NA |
The name of application role that created the entity, for data created programmatically. | No |
VARCHAR2(64) |
| Relative_Size_Indicator | CODE | NA |
An indicator of the relative size of the BLOB (Binary Large OBject) in the Histogram_Data attribute. The possible values are "Small", "Medium", and "Large". When the partitioning option is selected for a Seabed database, different storage areas (i.e., tablespaces in Oracle) are created to handle different sized objects more efficiently. The relative size indicator helps determine which storage area to use within the partitioning scheme. | No |
