	Business Rule Engine A business rules engine is a software system that executes one or more business rules in a runtime production environment. The rules might come from legal regulation ("An employee can be fired for any reason or no reason but not for an illegal reason"), company policy ("All customers that spend more than $100 at one time will receive a 10% discount"), or other sources. A business rule system enables these company policies and other operational decisions to be defined, tested, executed and maintained separately from application code. Rule engines typically support rules, facts, priority (score), mutual exclusion, preconditions, and other functions. Rule engine software is commonly provided as a component of a business rule management system which, among other functions, provides the ability to: register, define, classify, and manage all the rules, verify consistency of rules definitions (”Gold-level customers are eligible for free shipping when order quantity > 10” and “ma ...

	Production System (computer Science) A "production system " (or "production rule system") is a computer program typically used to provide some form of artificial intelligence, which consists primarily of a set of rules about behavior but it also includes the mechanism necessary to follow those rules as the system responds to states of the world. Those rules, termed productions, are a basic representation found useful in automated planning, expert systems and action selection. Productions consist of two parts: a sensory precondition (or "IF" statement) and an action (or "THEN"). If a production's precondition matches the current state of the world, then the production is said to be ''triggered''. If a production's action is executed, it is said to have ''fired''. A production system also contains a database, sometimes called working memory, which maintains data about current state or knowledge, and a rule interpreter. The rule interpreter must provide a mechanism for prioritizing productions when more than one is tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Production (computer Science) A production or production rule in computer science is a ''rewrite rule'' specifying a symbol substitution that can be recursively performed to generate new symbol sequences. A finite set of productions P is the main component in the specification of a formal grammar (specifically a generative grammar). The other components are a finite set N of nonterminal symbols, a finite set (known as an alphabet) \Sigma of terminal symbols that is disjoint from N and a distinguished symbol S \in N that is the ''start symbol''. In an unrestricted grammar, a production is of the form u \to v, where u and v are arbitrary strings of terminals and nonterminals, and u may not be the empty string. If v is the empty string, this is denoted by the symbol \epsilon, or \lambda (rather than leave the right-hand side blank). So productions are members of the cartesian product :V^NV^ \times V^* = (V^\setminus\Sigma^) \times V^, where V := N \cup \Sigma is the ''vocabulary'', ^ is the Kleene star ...

	Request For Production A request for production is a legal request for documents, electronically stored information, or other tangible items made in the course of litigation. In civil procedure, during the discovery phase of litigation, a party to a lawsuit may request that another party provide any documents that it has that pertain to the subject matter of the lawsuit. For example, a party in a court case may obtain copies of e-mail messages sent by employees of the opposing party. The responding party is required to furnish copies of any documents that are responsive to the request, except for those that are legally privileged. The responding party also can submit a response to the requestor explaining why the documents cannot be produced. For example, the responding party may indicate that documents are unavailable because they have been destroyed, that it would be unduly burdensome to produce the documents, or that the documents are not in possession of the responding party. However, the requestor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
