Data Warehouse (DWH) provides storage for huge amounts of historical data from heterogeneous operational sources in the form of multidimensional views, thus supplying sensitive and useful information which help decision-makers to improve the organization’s business processes. A data warehouse environment must ensure that data collected and stored in one big repository are not vulnerable. A revi...

Data warehouses are in use for more than a decade but companies are still finding it difficult to decide on the approach they should take for successful implementation. Data warehouse architecture plays a major role the successful construction of data warehouse. This paper proposes an approach of constructing local data marts at source and integrating them at enterprise level by creating physic...

The enterprise data warehouse is a repository of the enterprise’s data that is extracted from the operational databases. This repository is organized in a manner that facilitates querying, reporting and analysis. Since the data warehouse’s primary function is to support end-user analysis and facilitate decision making, the method in which the data warehouse is organized becomes critical to its ...

diseases management offers the benefits of lower disease occurrence, improved patient care, and lower healthcare costs. the key mechanism used to identify individuals at risk, stratify patients by risk level and track patients’ progress through the disease management is the data warehouse (dw). this review article describes operational systems, dw features and component and role of it in diseas...

in this paper, a multi-product continues review inventory control problem within batch arrival queuing approach (mqr/m/1) is modeled to find the optimal quantities of maximum inventory. the objective function is to minimize summation of ordering, holding and shortage costs under warehouse space, service level, and expected lost-sales shortage cost constraints from retailer and warehouse viewpoi...

After a thorough investigation of end user requirement differences from a Database and a Data Warehouse, a strong case is made for specific Data Warehouse Management Systems (DWMS), in contrast to the trend of utilizing DBMS for Data Warehouse construction. The three type (Temporal, Nested Relational, Multidimensional) DWMS hypothesis, an original concept of Yoshioki Ishii, President, Software ...

In this paper we shall discuss with the optimal ordering policy for two warehouse inventory model of non-instantaneous deteriorating items and stock-dependent demand. Here shortage is not allowed. Here the holding and deteriorating costs in both warehouses are different and assumed that the holding cost in the RW(rented warehouse) than in the OW(owned warehouse) the optimal solution are shown. ...
