Herman Hollerith (February 29, 1860 – November 17, 1929) was a German-American statistician, inventor, and businessman who developed an electromechanical tabulating machine for punched cards to assist in summarizing information and, later, in accounting.
Group method of data handling, a method to train arbitrarily deep neural networks was published by Alexey Ivakhnenko and Lapa in 1967, which they regarded as a form of polynomial regression, [19] or a generalization of Rosenblatt's perceptron. [20] A 1971 paper described a deep network with eight layers trained by this method. [21]
In the early 19th century, collection intensified, and the meaning of "statistics" broadened to include the discipline concerned with the collection, summary, and analysis of data. Today, data is collected and statistics are computed and widely distributed in government, business, most of the sciences and sports, and even for many pastimes.
Data science is multifaceted and can be described as a science, a research paradigm, a research method, a discipline, a workflow, and a profession. [4] Data science is "a concept to unify statistics, data analysis, informatics, and their related methods" to "understand and analyze actual phenomena" with data. [5]
SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce after learning about the relational model from Edgar F. Codd [12] in the early 1970s. [13] This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasirelational database management system, System R, which a group at IBM San ...
With Kristen Nygaard, invented the proto-object oriented language SIMULA: 1965 Davies, Donald: One of two independent inventors of the concept of digital packet switching used in modern computer networking including the Internet. [9] [20] Conceived of and named the concept for data communication networks (1965–66).
Data management comprises all disciplines related to handling data as a valuable resource, it is the practice of managing an organization's data so it can be analyzed for decision making. [ 1 ] Concept
In the late 1880s, the American Herman Hollerith invented data storage on punched cards that could then be read by a machine. [26] To process these punched cards, he invented the tabulator and the keypunch machine. His machines used electromechanical relays and counters. [27] Hollerith's method was used in the 1890 United States census.
