Unreferenced date December 2009 Domain knowledge is that valid knowledge used to refer to an area of human endeavor, 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 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 problem domain is simply looking at only the topics you are interested in, and excluding everything else. For example, if you were developing a system trying to measure good practice in medicine, you wouldn t include carpet drawings at hospitals in your problem domain. 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.

Time domain is a term used to describe the analysis of mathematical function mathematics function s, or physical signal information theory signal s, with respect to time . In the time domain, the signal or function s value is known for all real number s, for the case of continuous time , or at various separate instants in the case of discrete time . An oscilloscope is a tool commonly used to visualize real world signals in the time domain. Speaking non technically, a time domain graph shows how a signal changes over time, whereas a frequency domain graph shows how much of the signal lies within each given frequency band over a range of frequencies.

In 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.
