This paper presents a proposal for a Data Warehouse Conceptual Data Model which allows for the description of both the relevant aggregated entities of the domain| together with their properties and their relationships with other relevant entities|and the relevant dimensions involved in building the aggregated entities. The proposed Data Warehouse Conceptual Data Model is able to capture the dat...

This paper investigates the use of data warehouse and business intelligence capabilities to integrate with customers in the supply chain and improve insights into customer sales. By making that same data warehouse sales information available to customers, this paper explores how the data warehouse can provide additional value to those customers, eliminating asymmetries of information in the sup...

A data warehouse stores huge amounts of data collected from multiple sources and enables users to query that data for analytical and reporting purposes. Data in a data warehouse can be represented as a multidimensional cube. Data warehouse queries tend to be very complex, thus their evaluation requires long hours. Precomputing a proper set of the queries (building subcubes) may significantly re...

Modern enterprise data warehouses have complex workloads that are notoriously difficult to manage. Additionally, RDBMSs have many “knobs” for managing workloads efficiently. These knobs affect the performance of query workloads in complex interrelated ways and require expert manual attention to change. It often takes a long time for a performance expert to get enough experience with a large war...

multi-echelon inventory systems are one of the most important and attractive areas in modelling supply chain management so that several researches and studies have been done about. in this paper, the total cost function of a two-echelon inventory system with central warehouse and many identical retailers controlled by continuous review inventory policy is estimated. we have assumed the demand i...

traditional building technologies have much to teach us about how to design regionally appropriate structures. the orosi is one of these useful technologies, which has been used for many centuries in order to control the harsh sunlight in iran. this architectural element was rather important because the intensive solar radiation could easily damage valuable carpets used in most spaces in persia...

Metadata management has been identified as one of the major critical success factor in data warehousing projects, but the industrialization process of metadata management did not yet reach a satisfying level of maturity from both a methodological and a technological point of view; therefore every project has to build its own metadata management system following the methodology that better fits ...

Data warehouse is a subject-oriented, integrated, time-variant, and nonvolatile collection of data to provide the strategic information to the decision makers. Most of the data ware house project fails to meet the business requirements and business goals because of the improper requirement engineering phase. Building a data warehouse is a very challenging task. Data warehouse development can us...
