The problem of evolution in the ETL process is investigated. There is no good solution in spite of numerous attempts to solve this problem. A new model to provide data warehouse and ETL scenario evolution is suggested. This model unite two different models of evolution to provide more flexible solution.

BACKGROUND Over the last few years multiple studies have been published showing a great diversity in size of chloroplast genomes (cpGenomes), and in the arrangement of gene clusters, in the Euglenales. However, while these genomes provided important insights into the evolution of cpGenomes across the Euglenales and within their genera, only two genomes were analyzed in regard to genomic variabi...

This paper provides the motivation, implementation details, and evaluation of a lightweight distributed extract-transform-load (ETL) service designed for large scale ingestion of real-time data.

Sulfate functionalization on meso-TiO 2 ETL lowers the conduction band level and suppresses deprotonation of organic cations hybrid perovskite at perovskite/ETL interface, resulting in improved operational stability solar cells.

The increasing availability of data on the Web provided by the emergence of Web 2.0 applications and, more recently by Linked Data, brought additional complexity to data management tasks, where the number of available data sources and their associated heterogeneity drastically increases. In this scenario, where data is reused and repurposed on a new scale, the pattern expressed as Extract-Trans...

Extract-Transform-Load (ETL) handles large amount of data and manages workload through dataflows. ETL dataflows are widely regarded as complex and expensive operations in terms of time and system resources. In order to minimize the time and the resources required by ETL dataflows, this paper presents a framework to optimize dataflows using shared cache and parallelization techniques. The framew...

Business Intelligence (BI) is considered to have a high impact on businesses. Research activity has risen in the last years. An important part of BI systems is a well performing implementation of the Extract, Transform, and Load (ETL) process. In typical BI projects, implementing the ETL process can be the task with the greatest effort.

Enteropathy-type T-cell lymphoma (ETL) and ulcerative jejunitis (UJ) are rare disorders often occurring in patients with coeliac disease. The genetic events associated with the accumulation of intraepithelial lymphocytes in coeliac disease and tumour development are largely unknown. Deletions at chromosome 9p21, which harbours the tumour suppressor genes p14/ARF, p15/INK4b, and p16/INK4a, and 1...

The defects of OH in ZnO electron transport layer (ETL) processed by sol–gel was passivated glucose (Gl). An improved PCE 18.03% is obtained PM6:Y6-based cell. ZnO/Gl ETL shows generic improvement for other blend system based cells.

This paper reports the performance of an epitaxial layer (ETL) based gate modulated (GM-TFET) through 3D Technology Computer Aided Design (TCAD) simulations. The architecture utilizes effects both vertical tunneling and lateral phenomena to improve device performance. Attributes ETL, its thickness (tepi) doping concentration (Nepi) are varied their impact on electrical parameters such as transf...
