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.
DBA_MINING_MODEL_ATTRIBUTES describes the attributes of all mining models in the database.
USER_MINING_MODEL_ATTRIBUTES describes the attributes of the mining models owned by the current user. This view does not display the OWNER column.
| 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: 
 | |
| DATA_TYPE | VARCHAR2(12) | Data type of the attribute: 
 | |
| 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_ATTRIBUTESview only lists the attributes used by the model, therefore the value of this column is alwaysACTIVE. | |
| 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. |
