Methods, computer program products, and systems are presented. The methods computer program products, and systems can include, for instance: determining an insertion interval of a row for insertion into a decision table; and guiding insertion of the row for insertion into the decision table based on a result of the determining.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method comprising: determining, by one or more processor, an insertion interval of a row for insertion into a decision table; and guiding, by the one or more processor, insertion of the row for insertion into the decision table based on a result of the determining. 2. The method of claim 1, wherein the decision table is a sparse decision table. 3. The method of claim 1, wherein the determining includes applying a SUBSUMES operator defined as follows: Row1 SUBSUMES Row2 when, for each condition cell of Row1 (a) and (b) true: (a) If the cell has a defined value, then the corresponding cell in Row2 also has a defined value; (b) The value (or domain of values) of the cell equals (or includes) the value (or domain of value) of the corresponding cell in Row2. 4. The method of claim 1, wherein the guiding includes restricting insertion of a row for insertion at row indices other than the determined row insertion interval. 5. The method of claim 1, wherein the guiding includes prompting a user to define a row insertion request for the determined row insertion interval. 6. The method of claim 1, wherein the guiding includes highlighting a row representation of rows of the row insertion interval. 7. The method of claim 1, wherein the guiding includes restricting insertion of a row for insertion at row indices other than the determined row insertion interval, prompting a user to define a row insertion request for the determined row insertion interval, and highlighting a row representation of rows of the row insertion interval. 8. A computer program product comprising: a computer readable storage medium readable by one or more processing unit and storing instructions for execution by one or more processor for performing a method comprising: determining an insertion interval of a row for insertion into a decision table; and guiding insertion of the row for insertion into the decision table based on a result of the determining. 9. The computer program product of claim 8, wherein the decision table is a sparse decision table. 10. The computer program product of claim 8, wherein the determining includes applying a SUBSUMES operator defined as follows: Row1 SUBSUMES Row2 when, for each condition cell of Row1 (a) and (b) true: (a) If the cell has a defined value, then the corresponding cell in Row2 also has a defined value; (b) The value (or domain of values) of the cell equals (or includes) the value (or domain of value) of the corresponding cell in Row2. 11. The computer program product of claim 8, wherein the guiding includes restricting insertion of a row for insertion at row indices other than the determined row insertion interval. 12. The computer program product of claim 8, wherein the guiding includes prompting a user to define a row insertion request for the determined row insertion interval. 13. The computer program product of claim 8, wherein the guiding includes highlighting a row representation of rows of the row insertion interval. 14. The computer program product of claim 8, wherein the guiding includes restricting insertion of a row for insertion at row indices other than the determined row insertion interval, prompting a user to define a row insertion request for the determined row insertion interval, and highlighting a row representation of rows of the row insertion interval. 15. A system comprising: a memory; at least one processor in communication with memory; and program instructions executable by one or more processor via the memory to perform a method comprising: determining an insertion interval of a row for insertion into a decision table; and guiding insertion of the row for insertion into the decision table based on a result of the determining. 16. The system of claim 15, wherein the determining includes applying a SUBSUMES operator defined as follows: Row1 SUBSUMES Row2 when, for each condition cell of Row1 (a) and (b) true: (a) If the cell has a defined value, then the corresponding cell in Row2 also has a defined value; (b) The value (or domain of values) of the cell equals (or includes) the value (or domain of value) of the corresponding cell in Row2. 17. The system of claim 15, wherein the guiding includes restricting insertion of a row for insertion at row indices other than the determined row insertion interval. 18. The system of claim 15, wherein the guiding includes prompting a user to define a row insertion request for the determined row insertion interval. 19. The system of claim 15, wherein the guiding includes highlighting a row representation of rows of the row insertion interval. 20. The system of claim 15, wherein the guiding includes restricting insertion of a row for insertion at row indices other than the determined row insertion interval, prompting a user to define a row insertion request for the determined row insertion interval, and highlighting a row representation of rows of the row insertion interval.
