HCL Notes
rapid application development platform

HCL Notes (formerly Lotus Notes then IBM Notes) is a proprietary collaborative software platform for Unix (AIX), IBM i, Windows, Linux, and macOS, sold by HCLTech. The client application is called Notes while the server component is branded HCL Domino.
HCL Notes provides business collaboration functions, such as email, calendars, to-do lists, contact management, discussion forums, file sharing, websites, instant messaging, blogs, document libraries, user directories, and custom applications. It can also be used with other HCL Domino applications and databases. IBM Notes 9 Social Edition removed integration with the office software package IBM Lotus Symphony, which had been integrated with the Lotus Notes client in versions 8.x.
Lotus Development Corporation originally developed "Lotus Notes" in 1989. IBM bought Lotus in 1995 and it became known as the Lotus Development division of IBM. On December 6, 2018, IBM announced that it was selling a number of software products to HCLSoftware for $1.8bn, including Notes and Domino. This acquisition was completed in July 2019.
History
Lotus Notes's chief inspiration was PLATO Notes, created by David R. Woolley at the University of Illinois in 1973. In today's terminology, PLATO Notes supported user-created discussion groups, and it was part of the foundation for an online community which thrived for more than 20 years on the PLATO system.
