Abstract
We identify a number of simple, syntactic properties of recursive subgoals in linear single-rule and two-rule Datalog programs. These properties can be recognized in linear time and provide a sufficient condition for uniform 1-boundedness of single-rule programs. They can also be used to characterize both uniform 1-boundedness for single-rule programs and 1-boundedness for two-rule programs, when the programs belong to certain classes studied previously for the problem of boundedness. In addition, we provide an exact characterization for 1-boundedness of two-rule programs in which no EDB predicate is repeated in the recursive rule.
