A deductivesystem also called a deductive apparatus of a formal system consists of the axiom s or axiom schema ta and rules of inference that can be used to formal proof derive the theorem s of the system. ref Hunter, Geoffrey, Metalogic An Introduction to the Metatheory of Standard First Order Logic, University of California Pres, 1971 ref Such a deductivesystem is intended to preserve deductive reasoning deductive qualities in the formula mathematical logic formula s that are expressed in the system. Usually the quality we are concerned with is truth as opposed to falsehood. However, other modal logic modalities , such as justification or belief may be preserved instead. In order to sustain its deductive integrity, a deductive apparatus must be definable without reference to any intended interpretation of the language. The aim is to ensure that each line of a Mathematical proof derivation is merely a syntactic consequence of the lines that precede it. There should be no element of any Interpretation logic interpretation of the language that gets involved with the deductive nature of the system.

A deductive database system is a database system which can make Deductive reasoning deductions i.e. conclude additional facts based on wiktionary rule rules and facts stored in the deductive database. Datalog is the language typically used to specify facts, rules and queries in deductive databases. Deductive databases have grown out of the desire to combine logic programming with relational database s to construct systems that support a powerful formalism and are still fast and able to deal with very large datasets. Deductive databases are more expressive than relational databases but less expressive than logic programming systems. Deductive databases have not found widespread adoptions outside academia, but some of their concepts are used in today s relational databases to support the advanced features of more recent SQL standards. Deductive databases and logic programming Deductive databases reuse a large number of concepts from logic programming rules and facts specified in the deductive database language Datalog look very similar to those in Prolog . However, there are a number of important differences between deductive databases and logic programming Order sensitivity and procedurality in Prolog, program execution depends on the order of rules in the program and on the order of parts of rules these properties are used by programmers to build efficient programs. In database languages like SQL or Datalog , however, program execution is independent of the order of rules and facts. Special predicates In Prolog, programmers can directly influence the procedural evaluation of the program with special predicates such as the Cut logic programming cut , this has no correspondence in deductive databases. Function symbols Logic Programming languages allow Functional predicate function symbols to build up complex symbols. This is not allowed in deductive databases.

wiktionary Deductive reasoning Deductive reasoning , also called deductive logic , is reasoning which constructs or evaluates deductive Argument logic argument s. Deductive arguments are attempts to show that a conclusion logical consequence necessarily follows from a set of premises or hypotheses. A deductive argument is valid if the conclusion does follow necessarily from the premises, i.e., if the conclusion must be true provided that the premises are true. A deductive argument is Soundness sound if it is valid and its premises are true. Deductive arguments are valid or invalid, sound or unsound, but are never false nor true. Deductive reasoning is a method of gaining knowledge. An example of a deductive argument All men are mortal Socrates is a man Therefore, Socrates is mortal The first premise states that all objects classified as men have the attribute mortal . The second premise states that Socrates is classified as a man a member of the set men . The conclusion states that Socrates must be mortal because he inherits this attribute from his classification as a man.

According to it, scientific inquiry proceeds by formulating a hypothesis in a form that could conceivably be falsified by a test on observable data. A test that could and does run contrary to predictions of the hypothesis is taken as a Falsifiability falsification of the hypothesis. A test that could but does not run contrary to the hypothesis corroborates the theory. It is then proposed to compare the explanatory value of competing hypotheses by testing how stringently they are corroborated by their predictions.

The deductive nomological model or D N model is a Formal science formalized Citation needed date March 2011 view of science scientific explanation in natural language . It characterizes scientific explanations primarily as deductive reasoning deductive arguments with at least one natural law statement among its premises. Nomological comes from the Greek word nomos nomos , i.e., law. Background The D N model is known by many names, including the covering law model , the subsumption theory , Hempel s model , the Hempel Oppenheim model , and the Popper Hempel model of explanation Niiniluoto, 1995 . Its introduction in the philosophical literature is part of a broad general discussion about the nature of scientific explanation i.e., what it is, what it should be, etc. . The D N model is taught implicitly in schools, and approximates our pre theoretical conception of science, which many non experts hold. It was initially formalized by Carl Hempel and Paul Oppenheim in their article Studies in the Logic of Explanation 1948 . A sketch of it can be found in Karl Popper s Logic of Scientific Discovery 1934 . Formalization The model offers the following account of scientific explanation , where an explanation is set out as a formalized argument Let p be the explanandum the statement that describes the phenomenon or phenomena to be explained.

A system running this print architecture could traditionally be identified by the use of the user command Lp Unix lp as the primary interface to the print system, as opposed to the Berkeley Software Distribution BSD Line Printer Daemon protocol lpr command, though some systems provide lpr as an alias to lp . Typical user commands available to the SysV print system are lp Unix lp the user command to print lpstat shows the current print queue cancel deletes a job from the print queue lpadmin a sysadmin command that configures the print system lpmove a sysadmin command that moves jobs between queues The original System V printing system remains proprietary however, the Solaris print system, heavily modified from the original, is open source as part of the OpenSolaris project.
