Setting Analogy Between Fields
A unique feature of ESTARD Data Miner is that obtained rules and
decision trees can be used for
searching for data patterns in data sets.
If the structures (number of fields or their names and types) of the tables
from Learning Database and the
Analysed Database differ, you
can set analogy between fields. This data mapping feature allows to apply
rules and trees to search
any table, selected from the Analysed Database.
To set the fields mapping press the
button at the "Search a Database"
program tab to open the "Fields Analogy Settings" dialog:
- "Rule/Decision Tree Field Name" - the left side of the
control contains a list of Fields, found in the "Learning Database"
- "Analysed Database Field Name" - the right side
contains a list of Fields that can be set as an analogy. If the program
Fields of the same names and types, it sets an analogy
automatically. In case if some Fields do not have a list, this means
there are no Fields of the same type in the
"Analysed Database" table, and the analogy can't be set.
- "Apply " button - click it to apply all changes.
Note: IF-THEN Rules and Decision Trees containing Fields that have no analogy
will be ignored during Simple Select Queries.
