ALL_MINING_MODEL_ATTRIBUTES

ALL_MINING_MODEL_ATTRIBUTES describes the attributes of the mining models accessible to the current user.

Attributes correspond to the columns of data used to build a model. Columns with the same names and data types should be available in any data set to which the model is applied.

Column Datatype NULL Description
OWNER VARCHAR2(30) NOT NULL Owner of the mining model
MODEL_NAME VARCHAR2(30) NOT NULL Name of the mining model
ATTRIBUTE_NAME VARCHAR2(30) NOT NULL Name of the attribute
ATTRIBUTE_TYPE VARCHAR2(11)   Logical type of the attribute. The type is identified during the model build or apply process:
  • NUMERICAL - Numeric data

  • CATEGORICAL - Character data

DATA_TYPE VARCHAR2(12)   Data type of the attribute:
  • VARCHAR2

  • NUMBER

  • FLOAT

  • CHAR

  • NESTED TABLE

DATA_LENGTH NUMBER   Length of the data type
DATA_PRECISION NUMBER   Precision of a fixed point number. Precision, which is the total number of significant decimal digits, is represented as p in the data type NUMBER(p,s).
DATA_SCALE NUMBER   Scale of a fixed point number. Scale, which is the number of digits from the decimal to the least significant digit, is represented as s in the data type NUMBER(p,s).
USAGE_TYPE VARCHAR2(8)   Indicates whether the attribute was used to construct the model (ACTIVE) or not (INACTIVE). Some attributes may be eliminated by transformations or algorithmic processing. The *_MINING_MODEL_ATTRIBUTES view only lists the attributes used by the model, therefore the value of this column is always ACTIVE.
TARGET VARCHAR2(3)   Indicates whether the attribute is the target of a predictive model (YES) or not (NO). The target describes the result that is produced when the model is applied.
