Domain concept

A system requirement spec often reflects the business model closely, as in this case. Differences occur where the business model is general to several systems or where there are special mechanisms of interaction with the user apart from any domain concepts (for...

A domain object model is a model that describes key domain concepts and their relationships. Many of these concepts come from tangible objects in the real world of the problem domain. In the chemical informatics space, these are the objects that chemists are dealing with on a daily basis, such as compounds, structures, notebooks, and libraries. The domain analysis model being presented here focuses on those objects that are involved in the compound registration process. 

After the publication of the Strauss et al. article, there was considerable interest in whether a subtype of schizophrenia could be defined by positive or negative symptoms. Crow (1980) postulated the existence of two distinct syndromes within schizophrenia, Type I and Type II. Type I was characterized as having more positive symptoms, more acute, responding well to neuroleptics, and with limited intellectual impairment. Type II was defined by irreversible flat affect, insidious onset and chronic course, responding poorly to neuroleptics, and more often associated with gross brain abnormalities. Later, Crow clarified the two types could coexist within the same individual, thus bringing his ideas more in line with the domain concepts of positive and negative symptoms (Crow, 1985). 

Due to the large number of domain concepts, ever-changing application areas, newly arising insights, and the continuous update of technological capabilities for model representation, the development of product data models for a complex domain is deemed to be an evolutionary process. Since the early nineties, several product data models have been developed by the authors and their former colleagues, which model various aspects of the chemical engineering domain. The results are VeDa [10, 55], CLiP [14, 19], and OntoCAPE [325, 326], the second version of which has been released lately. 

Conceptually, the application domain concepts should be derived from the meta... 

While product data modeling in an application domain has focused traditionally on a detailed and complete representation of all domain concepts together with their relations and defining attributes, the IMPROVE approach has been radically different. The major focus has been on the design of an extensible architectural framework for product data modeling rather than on a detailed and comprehensive model itself. 

Subunit structure will be described in terms of (a) the amino terminal arm, (b) that part which binds the coenzyme, and (c) the part containing catalytic residues. The dinucleotide binding part is subdivided into two mononucleotide binding domains (Bi and B2) and these have been observed in other dehydrogenases 35. The catalytic part is also subdivided into two domains. The domain concept is illustrated by a distance plot 147,146) for LDH (Fig. 13) and discussed in a preceding review 35). 

Protein domains, the next level up in the hierarchy of protein constitution, are important enough to warrant a separate discussion. Domains can be defined based on function, structure, or sequence characterization in many cases the different approaches are compatible. We naturally adopt a structure-based definition a protein domain is a spatially distinct structure (or structural component) that could conceivably fold and function in isolation [63]. Some proteins consist of a single domain, while others are composed of multiple domains each folded separately from a subsection of the underlying amino acid chain. To this point, our notion of the genotype to phenotype relationship has been protein sequence protein structure. Given the discrete spatial nature of domains, protein SM sequence -> domain would be an equally valid definition. In fact, the notion of a protein fold (as in, "this fold is highly designable") translates naturally to the protein domain concept. 

Another example of application software is a banking system. Such software also deals with a particular application domain and its requirements may be stated in terms of the domain concepts such as customer, account, interest rate, deposit, and so on. 

Dispersion (frequency dependence according to the laws of relaxation) is the correspondent frequency domain concept of relaxation permittivity as a function of frequency. Even if the concept of relaxation is linked with step functions, it can of course be studied also with sine waves. An ideal step function contains all frequencies, and dispersion can be analyzed with a step function followed by a frequency (Fourier) analysis of the response signal or with a sinusoidal signal of varying frequency. 

The common view of the structure of liquid crystalline polymers at rest is that of randomly oriented domains of highly ordered regions embedded a matrix of lesser order. We have shown this idea in the schematic drawing in Figure 4. The domain concept is substantiated...

Fig. 2. By successively refining metamodels, a family of closely related metamodels is created. For clarity, the metamodel transformations and the domain concepts introduced by refinement specifications of Figure 1 are not shown in this figure.

Conceptual mapping between metamodels The models in this mapping axe all layer 2 MOF models, called M2-models. For example, in Figure 3, the company Y conceptual model or the branch Z conceptual model are M2-models. In a reuse scenario, this implies that the conceptual mapping between metamodels only focuses on domain concepts. 

Changes in the represented domains, such as the introduction/removal of domain concepts (e.g., the removal of RESISTANCE VALUE column from Table 7.1 since it is not relevant anymore in the domain) or granularity changes (e.g., adding more detailed information than at signal level) ...
