Data Warehouse Architecture through Viewpoint of Information System Architecture

“…At the end of the decade of 80's and beginning of the 90, the first concepts and models of Information Systems Architecture (ISA) were defined, considering since the strategic planning until the data storage [20]. The goal was define a set of elements involved in the process of development and implantation of Information Systems (IS).…”

“…The goal was define a set of elements involved in the process of development and implantation of Information Systems (IS). In this context, Zachman [21] defined a IS framework which, according to Tait [20], has been used as the basis to other researchers in the ISA definition. At the end of the decade of 90's, Inmon et al [10], based on the Zachman framework, defined a model for DW architecture.…”
