ETL tools are typically used by a broad range of professionals – from students in computer science looking to quickly import large data sets to database architects in charge of company account management, ETL tools have become a convenient tool that can be relied on to get maximum performance.
Extract, transform, load (ETL) design and development is the design of some of the heavy procedures in the data warehouse and business intelligence system. Kimball et al. suggests four parts to this process, which are further divided into 34 subsystems: [3] Extracting data; Cleaning and conforming data; Delivering data for presentation ...
EDSAC, on which the book was based, was the first computer in the world to provide a practical computing service for researchers. [2] Demand for the book was so limited initially that it took six years to sell out the first edition. [7] As computers became more common in the 1950s, the book became the standard textbook on programming for a time ...
Extract, load, transform (ELT) is an alternative to extract, transform, load (ETL) used with data lake implementations. In contrast to ETL, in ELT models the data is not transformed on entry to the data lake, but stored in its original raw format. This enables faster loading times.
William Richard (Rich) Stevens (February 5, 1951 – September 1, 1999) was a Northern Rhodesia–born American author of computer science books, in particular books on Unix and TCP/IP. [ 1 ] Biography

Davies' work on data communications and computer network design has been described as the "cornerstone" technology used in the development of the Internet, which is a global system of connected computer networks (a network of networks). [68] [49] [69] [70] [71]
Apache NiFi is a software project from the Apache Software Foundation designed to automate the flow of data between software systems.Leveraging the concept of extract, transform, load (ETL), it is based on the "NiagaraFiles" software previously developed by the US National Security Agency (NSA), which is also the source of a part of its present name – NiFi.
