His research focused on the design of large-scale database management systems, the protection of their content, often using knowledge-based techniques. After his formal retirement he focused on valuation methods for intellectual property and intellectual capital. Early life and education Gio Wiederhold was born June 24, 1936, in Varese, Italy. He graduated C.Ae. cum laude in Aeronautical Engineering from the TMS Technicum in Rotterdam, Netherlands in 1957. From 1957 to 1958 he did graduate work at the Technische Hogeschool in Delft.

Artificial Intelligence
Artificial intelligence (AI) is intelligence—perceiving, synthesizing, and inferring information—demonstrated by machines, as opposed to intelligence displayed by animals and humans. Example tasks in which this is done include speech recognition, computer vision, translation between (natural) languages, as well as other mappings of inputs. The ''Oxford English Dictionary'' of Oxford University Press defines artificial intelligence as: the theory and development of computer systems able to perform tasks that normally require human intelligence, such as visual perception, speech recognition, decision-making, and translation between languages. AI applications include advanced web search engines (e.g., Google), recommendation systems (used by YouTube, Amazon and Netflix), understanding human speech (such as Siri and Alexa), self-driving cars (e.g., Tesla), automated decision-making and competing at the highest level in strategic game systems (such as chess and Go). ...

Knowledge Base
A knowledge base (KB) is a technology used to store complex structured and unstructured information used by a computer system. The initial use of the term was in connection with expert systems, which were the first knowledge-based systems. Original usage of the term The original use of the term knowledge base was to describe one of the two sub-systems of an expert system. A knowledge-based system consists of a knowledge-base representing facts about the world and ways of reasoning about those facts to deduce new facts or highlight inconsistencies. Properties The term "knowledge-base" was coined to distinguish this form of knowledge store from the more common and widely used term ''database''. During the 1970s, virtually all large management information systems stored their data in some type of hierarchical or relational database. At this point in the history of information technology, the distinction between a database and a knowledge-base was clear and unambiguous. A databas ...

Column-oriented DBMS
A column-oriented DBMS or columnar DBMS is a database management system (DBMS) that stores data tables by column rather than by row. Benefits include more efficient access to data when only querying a subset of columns (by eliminating the need to read columns that are not relevant), and more options for data compression. However, they are typically less efficient for inserting new data. Practical use of a column store versus a row store differs little in the relational DBMS world. Both columnar and row databases can use traditional database query languages like SQL to load data and perform queries. Both row and columnar databases can become the backbone in a system to serve data for common extract, transform, load (ETL) and tools. Description Background A relational database management system provides data that represents a two-dimensional table of columns and rows. For example, a database might have this table: This simple table includes an employee identifier (EmpId), name f ...

Stanford University Medical School
Stanford University School of Medicine is the medical school of Stanford University and is located in Stanford, California. It traces its roots to the Medical Department of the University of the Pacific, founded in San Francisco in 1858. This medical institution, then called Cooper Medical College, was acquired by Stanford in 1908. The medical school moved to the Stanford campus near Palo Alto, California, in 1959. The School of Medicine, along with Stanford Health Care and Lucile Packard Children's Hospital, is part of Stanford Medicine. Stanford Health Care was ranked the fourth best hospital in California (behind UCLA Medical Center, Cedars-Sinai Medical Center, and UCSF Medical Center, respectively). History In 1855, Illinois physician Elias Samuel Cooper moved to San Francisco in the wake of the California Gold Rush. In cooperation with the University of the Pacific (also known as California Wesleyan College), Cooper established the Medical Department of the Universi ...

NATO
The North Atlantic Treaty Organization (NATO, ; french: Organisation du traité de l'Atlantique nord, ), also called the North Atlantic Alliance, is an intergovernmental military alliance between 30 member states – 28 European and two North American. Established in the aftermath of World War II, the organization implemented the North Atlantic Treaty, signed in Washington, D.C., on 4 April 1949. NATO is a collective security system: its independent member states agree to defend each other against attacks by third parties. During the Cold War, NATO operated as a check on the perceived threat posed by the Soviet Union. The alliance remained in place after the dissolution of the Soviet Union and has been involved in military operations in the Balkans, the Middle East, South Asia, and Africa. The organization's motto is ''animus in consulendo liber'' (Latin for "a mind unfettered in deliberation"). NATO's main headquarters are located in Brussels, Belgium, while NATO ...
