achieving the organizational objectives needs employees’ behavior and their collaboration with management. strategic behavior-driven is depend on different factors. the aim of this article is to determine the impact of factors on strategic behavior-driven. a conceptual model was developed and tested on a survey in social insurance company of tehran which employees’ participated. data collected ...

modeling is one of the most interesting areas in various fields of science. unfortunately data quality, which has an important role in the modeling, is not considered. in fact, most often processes encounter disturbances which results in the collection of abnormal data and may lead to a model different from the real behavior of the process. on the other hand, most of real industrial processes a...

In this paper we describe a framework for the automatic transformation of databases from the conceptual to the internal level. Our approach ts in with the ANSI/SPARC three level architecture for database management systems. The framework consists of three components: structures (database schemata), populations (database contents) and operations (database manipulations). On the conceptual level ...

This paper proposes an extension to the Object-Role Modeling approach to support formal declaration of dynamic rules. Dynamic rules differ from static rules by pertaining to properties of state transitions, rather than to the states themselves. In this paper, application of dynamic rules is restricted to so-called single-step transactions, with an old state (the input of the transaction) and a ...

How classes of things and properties in general should be represented in conceptual models is a fundamental issue. For example, proponents of object-role modelling argue that no distinction should be made between the two constructs, whereas proponents of entity-relationship modelling argue the distinction is important but provide ambiguous guidelines about how the distinction should be made. In...

At Guidant, a Boston Scientific Company, systems that collect data in support of medical device clinical research trials must be capable of collecting large, dynamic sets of attributes that are often reused in later research activities. Their resultant design, based on conceptual analysis using Object Role Modeling (ORM), transforms each unique business fact into an instance in a highly normali...

Context-aware applications rely on implicit forms of input, such as sensor-derived data, in order to reduce the need for explicit input from users. They are especially relevant for mobile and pervasive computing environments, in which user attention is at a premium. To support the development of context-aware applications, techniques for modelling context information are required. These must ad...

Ontologies are key enablers for sharing precise and machine-understandable semantics among different applications and parties. Yet, for ontologies to meet these expectations, their quality must be of a good standard. The quality of an ontology is strongly based on the design method employed. This paper addresses the design problems related to the modelling of ontologies, with specific concentra...

the present study investigated the mediating role of organizational citizenship behavior (ocb) in the relationship between job satisfaction, turnover, and organizational identification. the population of the present study included all employees working at tehran municipality at district 2 and the sample consisted of 260 employees selected using random sampling and cochran formula. the research ...
