Deductive reasoning is the process of drawing a conclusion based on premises that are generally assumed to be true. A deductive database consists of intensional and extensional databases. To address this problem, we describe a probabilistic deductive database, called TensorLog, in which reasoning uses a differentiable process. Forexample, the RDBMS that provide recursive SQL have based their implementations ondeductive database standards.A more viable approach is to use a regular relational database with an added Datalog layer forlogic programming.

Query optimization of PHI is the combination of query transformation and techniques developed for relational databases. While these operators allow the simple expression of many database programs, it is possible to write simple programs with a complicated semantics (as in the case for negations), and so many of the concepts introduced for negation (e.g., stratification) are also used for aggregate operators.
