This function returns a table containing the rules in a value of type DM_RuleModel.
Parameters
- ruleModel
- A value of type DM_RuleModel
Return Value
The return value is of type TABLE
| Column | Data type | Purpose |
|---|---|---|
| Id | INTEGER | Is a number generated to identify the rules. |
| headName | VARCHAR(1024) | Contains the head item of the rule after name mapping (if any). |
| head | VARCHAR(1024) | Uses the original item before name mappings. |
| bodyId | INTEGER | Is a generated identifier to allow joining the resulting table with a table generated by DM_getRuleBodies. Note: Values of BODYID may appear in several rows, if there are rules with identical sets of items in their bodies. |
| length | SMALLINT | Is a concatenation of the names of all body items separated by the term 'AND'. The body items and their names can be determined using the table DM_getRuleBodies. |
| bodyText | VARCHAR(4096) | Is a count of all items in the head and body. |
| support | REAL | Is the rule support and contains percentage values between 0.0 and 100.0. The support of an association rule is the percentage of groups that contain all of the items listed in that association rule. |
| confidence | REAL | Is the rule confidence and contains percentage values between 0.0 and 100.0. The confidence of an association rule is a percentage value that shows how frequently the rule head occurs among all the groups containing the rule body. |
| lift | REAL | Indicates how much more confidence the rule has as might be expected if the items were statistically independent; the value is given as a positive factor. The lift of a rule is the ratio of confidence to the expected confidence. It indicates how much more confidence the rule has as might be expected if the items were statistically independent. |
