This article emphasizes the use of Unified Modeling Language, UML in the specification of models based on ontologies in the representation of domains of knowledge, emphasizing the importance of semantic and of treatment ...

Abstract: In a Data Warehouse (DW), ETL processes (Extraction, Transformation, Load) are responsible for extracting, transforming and loading data from the data sources into the DW. A good design of these processes in the ...

BACKGROUND: A data warehouse (DW) is an integrated collection of subject-oriented data in the support of decision making. Importantly, the integration of data sources is achieved through the use of ETL (Extract, Transform, ...

There are several modeling methods, techniques and tools available in order to facilitate the understanding and the analysis of the complexity of the modem organizations. Such methods, techniques and tools are used to make ...

We discuss the mass splitting between the the top and bottom quarks in a technicolor scenario. The model proposed here contains a left-right electroweak gauge group. An extended technicolor group and mirror fermions are ...
