An MDA approach for the development of data warehouses
نویسندگان
چکیده
These last years, the sources of data became very heterogeneous and massive. The term "big data" is born to indicate this phenomenon. Unfortunately, he becomes difficult to manage big data to power the decisional system, and also it increases the time of interrogation of data from data warehouses. Several research works focused recently, on the proposal for the architectures of data warehouses for this type of data ‘’big data’’, and on the implementation of new algorithms of interrogation of these warehouses to improve the time of the answers. This article proposes a Model-Driven Architecture (MDA) approach for the development of data warehouses independently of any execution platform, to allow the facilitation of the development of these data warehouses as well as the migration of information systems based on relational DBMS to systems NoSQL.

Automatic Generation of Secure Multidimensional Code for Data Warehouses by using QVT Transformations: an MDA Approach
Data Warehouses manage vital information for the decision making process, which may be discovered by unauthorized users if we do not establish security measures in all the stages of the development process. We have proposed an MDA architecture to develop secure Data Warehouses which allows them to be modeled at different abstraction levels (business, conceptual, logical and code level). We take...
متن کاملApplying the i* Framework to the Development of Data Warehouses
Data warehouse design has been traditionally guided by an in-depth analysis of the underlying operational data sources, thus overlooking an explicit stage in which information requirements of decision makers are addressed. This scenario has prompted that the deployed data warehouse often fails in delivering the expected support of the decision making process. To overcome this problem, we propos...

متن کاملAn MDA Approach and QVT Transformations for the Integrated Development of Goal-Oriented Data Warehouses and Data Marts
To customize a data warehouse, many organizations develop concrete data marts focused on a particular department or business process. However, the integrated development of these data marts is an open problem for many organizations due to the technical and organizational challenges involved during the design of these repositories as a complete solution. In this article, the authors present a de...
متن کاملA Reliability Approach on Redesigning the Warehouses in Supply Chain with Uncertain Parameters via Integrated Monte Carlo Simulation and Tuned Artificial Neural Network
In this paper, a reliability approach on reconfiguration decisions in a supply chain network is studied based on coupling the simulation concepts and artificial neural network. In other words, due to the limited budget for warehouse relocation in a supply chain, the failure probability is assessed for determining the robust decision for future supply chain configuration. Traditional solving ...
