This paper addresses a multiperiod integrated model that plans deliveries to customers based upon inventories (at warehouse and customer locations) and vehicle routes. The model determines replenishment quantities and intervals at the warehouse, and distribution lots and delivery routes at customer locations. We investigate coordination of customer and warehouse replenishment decisions and illu...
We present a technique for automatic expiration of data in a historical data warehouse that preserves answers to a known and fixed set of first-order queries. In addition, we show that for queries with output size bounded by a function of the active data domain size (the number of values that have ever appeared in the warehouse), the size of the portion of the data warehouse history needed to a...
The data warehouse is considered to be the best way to organize transactional data. However, as many researches claim data warehouse should be augmented with external textual information. The objective of this chapter is to examine the requirements for profiling in the data warehouse environment. Profiles created in the data warehouse are then utilized to filter information. The goal of the ske...
Data warehouses have become an instant phenomenon in many large organizations that deal with a massive amount of information. Drawing on the experiences from the systems development field, we surmise that an effective CASE tool will enhance the success of warehouse implementations. Thus, we present a CASE tool designed to generate the SQL queries necessary to build a warehouse from a set of ope...
E-Business have a variety of on-line transaction processing (OLTP) systems and operational database. Data Warehouse is different from operational database. A data warehouse is a subject-oriented, integrated, time-variant, and non-volatile collection of data in support of management's decision-making process. The features of Data Warehouse cause the its design process and strategies to be differ...
In this chapter, we present the Multimodal Warehouse Project, which aimed at applying multimodal interaction to a warehouse picking process. We provide an overview of the warehouse picking procedure as well as the overall architecture of the multimodal picking application and technologies applied to design the application. Furthermore, we describe the execution of user tests of the picking appl...
Based on an actual dataset of college human resources, we analyzed the data warehouse technologies and combined them with the pracical work. The snowflake structure has been described about a data warehouse of university human resource and the data warehouse has been constructed. This paper reduces and categorizes features by explorative data analysis. When the data warehouse had built and appl...
Science and technology in Brazil are areas that have few available resources and many times these scarce resources are badly used. The data warehouse is a tool that can make possible a better distribution of these resources. In this article are considered some issues in the development of a data warehouse for Science & Technology management. The paper describes the necessity of a supporting sys...
Current data warehouse and OLAP technologies are applied to analyze the structured data that companies store in databases. The context that helps to understand data over time is usually described separately in text-rich documents. This paper proposes to integrate the traditional corporate data warehouse with a document warehouse, resulting in a contextualized warehouse. Thus, the user first sel...
The bottleneck of a data warehouse implementation is the ETL (extraction, transformation, and load) process, which carries out the initial population of the data warehouse and its further (usually periodical) updates. There is a number of software products supporting the OLAP analysis. However, the ETL process implementation is not repeatable in a significant way. This paper reports on a resear...
