Whois & Analysis for postgresqltutorial.com

PostgreSQL, often simply Postgres, is an object-relational database (ORDBMS) i.e. an RDBMS, with additional (optional use) "object" features with an emphasis on extensibility and standards compliance.

As a database server, its primary functions are to store data securely and return that data in response to requests from other software applications.

It can handle workloads ranging from small single-machine applications to large Internet-facing applications (or for data warehousing) with many concurrent users; on macOS Server, PostgreSQL is the default database; and it is also available for Microsoft Windows and Linux (supplied in most distributions).

An application program (app or application for short) is a computer program designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user.

Examples of an application include a word processor, a spreadsheet, an accounting application, a web browser, a media player, an aeronautical flight simulator, a console game or a photo editor.

The collective noun application software refers to all applications collectively.

This contrasts with system software, which is mainly involved with running the computer.

Database administrators (DBAs) use specialized software to store and organize data.

The role may include capacity planning, installation, configuration, database design, migration, performance monitoring, security, troubleshooting, as well as backup and data recovery.

A software developer is a person concerned with facets of the software development process, including the research, design, programming, and testing of computer software.

Other job titles which are often used with similar meanings are programmer, software analyst, and software engineer.

Machine learning is the subfield of computer science that, according to Arthur Samuel in 1959, gives "computers the ability to learn without being explicitly programmed." Evolved from the study of pattern recognition and computational learning theory in artificial intelligence, machine learning explores the study and construction of algorithms that can learn from and make predictions on data – such algorithms overcome following strictly static program instructions by making data driven predictions or decisions, through building a model from sample inputs.

Machine learning is employed in a range of computing tasks where designing and programming explicit algorithms with good performance is difficult or unfeasible; example applications include email filtering, detection of network intruders or malicious insiders working towards a data breach, optical character recognition (OCR), learning to rank and computer vision.
