Performance Improvement Techniques for Customized Data Warehouse

Data Warehouse Performance

A data warehouse is a large electronic repository of information that is generated and updated in a structured manner by an enterprise over time to aid business intelligence and to support decision making. Data stored in a data warehouse is non-volatile and time variant and is organized by subjects in a manner to support decision making (Inmon, Rudin, Buss, & Sousa, 1998). Data warehousing has ...

Techniques for Bluetooth Performance Improvement

This paper examines the application of some techniques in Bluetooth communications expected to improve system’s performance under certain environmental conditions. The transmitter diversity Alamouti scheme [1] and receiver diversity have been evaluated and compared to the standard single antenna transmitter and receiver system by means of the achievable BER. Some analytical considerations about...

The intranet data warehouse - tools and techniques for building an intranet-enabled data warehouse

Investigating the performance improvement by sampling techniques in EEG data

In this paper the performance of oversampling methods such as SMOTE (Synthetic Minority Over-sampling Technique) and PCA (Principal Component Analysis) which are used for preprocessing are applied for the Brain computer interface dataset. The pre-processed data is used for classification by SMO and Naïve Bayes. In the EEG recordings, the transient events are detected while predicting the condit...

A survey of query recommendation techniques for data warehouse exploration

Lots of data are gathered in datawarehouses that are navigated and explored for analytical purposes. Only recently has the problem of recommending a datawarehouse query to a datawarehouse user attracted attention. In this paper, we propose a simple formal framework for expressing datawarehouse query recommendations. We propose to see the problem of recommending a datawarehouse query for explora...
