Flow-based programming defines applications using the metaphor of a "data factory". It views an application not as a single, sequential process, which starts at a point in time, and then does one thing at a time until it is finished, but as a network of asynchronous processes communicating by means of streams of structured data chunks, called "information packets" (IPs).
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.
William Stallings is an American author. He has written computer science textbooks on operating systems , computer networks , computer organization , and cryptography . Early life
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 ...
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.
