In this paper, we present an architecture for a data warehouse that provides convenient, flexible, and high-performance access to tape-resident data. Data warehouses allow an organization to store and analyze operational data. Many data warehouses (e.g., for telecommunications) create very large data sets that can be economically stored only on tertiary storage. At the same time, data analysts ...

In daily life, vitamins fruits and vegetables play a very important role in human life. The farmer produces grains or huge quantities. Due to lack of storage problem suffers. It is necessary store all these things special warehouse. Thus, improper essential meet the increasing demands. Storage time fruit quality are greatly influenced by environmental factors. Therefore, it for environment perf...

A data warehouse stores information that is collected from multiple, heterogeneous information sources for the purpose of complex querying and analysis. Information in the warehouse is typically stored in the form of materialized views. One of the most important tasks when designing a warehouse is the selection of materialized views to be maintained in the warehouse. The goal is to select a set...

The amounts of data available to decision makers are increasingly important, given the network availability, low cost storage and diversity of applications. To maximize the potential of these data within the National Social Security Fund (NSSF) in Tunisia, we have built a data warehouse as a multidimensional database, cleaned, homogenized, historicized and consolidated. We used Oracle Warehouse...

View Materialization is an effective method to increase query efficiency in a data warehouse. However, one encounters the problem of space insufficiency if all possible views are materialized in advance. Reducing query time by means of selecting a proper set of materialized views with a lower cost is crucial for efficient data warehousing. In addition, the costs of data warehouse creation, quer...

This paper discusses an implementation of database signatures. Previous work demonstrates how to use signatures to reduce base table storage requirements in a data warehouse thereby improving performance of database administration tasks as well as complex queries. This work builds upon prior work by showing how signatures enable efficient indexing. This efficient indexing strategy relies partly...

Firstly, the basic conditions of fungicide were introduced, its action principle was analyzed, use method in military warehouse put forward, and factors influencing application effect discussed.

In recent years, various researchers have discussed a two warehouse inventory system. This kind of system was first discussed by Hartely (1976) [10]. Hartely presented a basic two-warehouse model, in which the cost of transporting a unit from rented warehouse (RW) to own warehouse (OW) was not considered. Sarma (1983)[20] developed a deterministic inventory model with infinite replenishment rat...
