Unreferenced date December 2009 Domain knowledge is that valid knowledge used to refer to an area of human endeavour, an autonomous computer activity, or other specialized discipline. Domain expert Specialists and experts use and develop their own domain knowledge. If the concept domain knowledge or domain expert is used, we emphasize a specific domain which is an object of the discourse interest problem. Knowledge capture More particular, in software engineering , domain knowledge is knowledge about the environment in which the target system operates, for example, software agent s. Domain knowledge is important, because it usually must be learned from software users in the domain as domain specialists experts , rather than from software developers. Expert s domain knowledge frequently informal and ill structured is transformed in computer programs and active data, for example in a set of rules in knowledge bases, by knowledge engineer s. Communicating between end users and software developers is often difficult. They must find a common language to communicate in. Developing enough shared vocabulary to communicate can often take a while. The same knowledge can be included in different domain knowledge. Knowledge which may be efficient in every domain is called domain independent knowledge, for example logic s and mathematics. Operations on domain knowledge are performed by meta knowledge .

A domain model that encapsulates methods within the entities is more properly associated with Object Oriented Modeling object oriented models . The domain model provides a structural view of the domain that can be complemented by other dynamic views, such as Use Case models.

In this example the domain refers to relevant topics solely within your interest medicine. This points to one of the limitations of overly specific and bounded problem domains, one may think they are interested in medicine and not interior design, but a better solution exists outside of the problem domain as it was initially conceived.

In abstract algebra , a Schreier domain is an integrally closed integral domain where every nonzero element is primal i.e., whenever x divides yz , x can be written as x x sub 1 sub x sub 2 sub so that x sub 1 sub divides y and x sub 2 sub divides z . An integral domain is said to be pre Schreier if every nonzero element is primal. A GCD domain is an example of a Schreier domain. The term Schreier domain was introduced by P. M. Cohn in 1960s. The term pre Schreier domain is due to Muhammad Zafrullah. In general, an irreducible element is primal if and only if it is a prime element . Consequently, in a Schreier domain, every irreducible is prime. In particular, an atomic domain atomic Schreier domain is a unique factorization domain this generalizes the fact that an atomic GCD domain is a UFD.

Gilmer, Commutative semigroup rings , University of Chicago Press, 1984, p. 172. ref For a polynomial in X over a GCD domain ... , which is valid over GCD domains. Examples A unique factorization domain is a GCD domain. Among the GCD domains, the unique factorization domains are precisely those that are also atomic domain s which ... . A B zout domain i.e., an integral domain where every finitely generated ideal is principal is a GCD domain. Unlike principal ideal domain s where every ideal is principal , a B zout domain need not be a unique factorization domain for instance the ring of entire function s is a non atomic B zout domain, and there are many other examples. An integral domain is a Pr fer domain Pr fer GCD domain if and only if it is a B zout domain. Fact date April 2009 If R is a non atomic GCD domain, then R X is an example of a GCD domain that is neither a unique factorization domain since it is non atomic nor a B zout domain since X and a non invertible and non zero element a of R generate an ideal not containing ... more details
