Summary

Abstract

This entity represents the individual samples of a type that may be collected from an observed haul. It is header information for species composition. If there are rare species present in sample and there exist multiple predominant species, a recursive subsample or subsamples may be created. The sum of the weights of the subsamples must be less than or equal to the parent sample.

Entity Information

Entity Type
Data Table

Data Attribute / Type Description
SEQ_NUMBER
NUMBER 		Sequence generated unique identifier for a history table. Every history table has a unique sequence assigned to it all start with 1, increment by 1 and do not cycle.
CHANGED_BY
VARCHAR2 		Oracle user who made a change to the transaction table record.
DATE_CHANGED
DATE 		Timestamp of change to transaction record.
CRUISE
NUMBER 		Sequence generated by Norpac and supplied to the observer as an unique identifier for an observer cruise record.
SAMPLE_SEQ
NUMBER 		Sequence generated unique identifier of a sample
PARENT_SAMPLE_SEQ
NUMBER 		Sequence generated unique identifier of a sample
SAMPLE_NUMBER
NUMBER 		Sequence within either haul or offload parent. This value is auto-generated but not necessarily unique.
OFFLOAD_SEQ
NUMBER 		Sequence generated unique identifier for an offload record
HAUL_SEQ
NUMBER 		Sequence generated unique identifier for a haul record
COMBINED_SAMPLE_FLAG
VARCHAR2 		Identifies whether unique samples within a haul have been aggregated together.
PRESORTED_FLAG
VARCHAR2 		This flag indicates that child species composition records did not come from and unsorted catch. Generally if a single large animal was removed before sampling began and so was not available for inclusion in any random sample
TOTAL_SAMPLE_WEIGHT
NUMBER 		Total weight in kg of this sample.
SAMPLE_HOOKS_POTS
NUMBER 		Number of hooks or pots sampled.
PERMIT
VARCHAR2 		Unique Code identifying a vessel or Processor - inherited from the NORPAC data set and created by the RAM division in Juneau
SPECIES_COMP_IN_SAMPLE
VARCHAR2 		This flag indicates that fish were found or were absent in this sample - in the latter case composition records are not permitted and the sample is ignored for extrapolations.
SAMPLE_DESIGN_FLAG
VARCHAR2 		Identifies this sample as complying (Y) or differing (N) from the protocol declared at the haul level.
NUMBER_OF_SEGMENTS_SAMPLED
NUMBER 		The number of segments (skates, racks) of hooks which went into this sample. This number may be fractional.
SAMPLE_HOOKS_OVERIDE_FLAG
VARCHAR2 		This flag identifies an observer overide of the computed sample hooks - pots variable. The setting of the flag to Y will prohibit the automatic computation of sample hooks-pots from haul-hook-count * number-of-segments-sampled.
SAMPLED_BY
NUMBER 		Cruise of sampling observer.

Title: Table: ATL_SAMPLE_H
Short Name: ATL_SAMPLE_H
Status: Completed
Abstract:

This entity represents the individual samples of a type that may be collected from an observed haul. It is header information for species composition. If there are rare species present in sample and there exist multiple predominant species, a recursive subsample or subsamples may be created. The sum of the weights of the subsamples must be less than or equal to the parent sample.
Purpose:

Histories of all changes to data are maintained by trigger code on the parent table; allowing change control by user and datetime for all updates and delete events.
