domain model

domain model

(systems analysis)
1. A definition of the functions, objects, data, requirements, relationships and variations in a particular domain.

2. A product of domain analysis which provides a representation of the requirements of the domain. The domain model identifies and describes the structure of data, flow of information, functions, constraints and controls within the Domain that are included in software systems in the domain. The Domain Model describes commonalities and variabilities among requirements for software systems in the domain.

It is centered around Tamot, a task and domain model editor that uses an underlying XML-based language to represent: (1) task models written in the Diane+ modeling language (Tarby & Barthet, 1996) and (2) their accompanying domain models (3) written in a simple KL-ONE styled knowledge base (Brachman & Schmolze, 1985).
CBM does not require an executable domain model, and is applicable in situations in which such a model would be difficult to construct (such as database design or SQL query generation).
In domain analysis common characteristics from similar systems are generalized; objects and operations common to all systems within the same domain are identified; and a domain model is defined to describe the relationships between the objects [Prieto-Diaz and Freeman 1987].
In the following sections we will discuss trends of the planning area that emerged from the competition, and the new domain models introduced.
Usually the educational domain is divided into two parts: one represents the target knowledge of the learning process and is called domain model, and the other defines rules or procedures governing the process and is called the pedagogical/adaptive/operational model.
These tasks are defined using the Problem specification (that includes Interaction Units) of the domain model of the underlying ITS (see Section 3.
Model Interpreters not only map domain models (such DSP Models) to executable models (such as the Multigraph Computational Model), they separate them, too.
The combination of a metamodel, a set of initial entities and relationships, and a set of context inference/ reasoning/action algorithms composes a CCRF domain model for a specific application (figure 3).
He specializes in Domain Model, Use Case Model and Analysis.
In particular, within the service-oriented learning context, our approach proposes a set of mechanisms that, based on an instructional domain model, address the identification and classification of candidate services.
Creating these Q-matrices for various test criteria we show that the new domain model results in consistently better learning curve fits as shown by cross-validation.
But the DESIRE, the user may ask DM-TAO--DESIRE's experimental intelligent assistant for concept assignment--to scan the code for him and present a list of candidate concepts based on the knowledge represented in its domain model (DM) knowledge base.
