fourth generation programming language

Fourth generation languages are close to natural language and were built with the concept that certain applications could be generalised by adding limited programming ability to them. or 4GL, are languages that consist of statements similar to statements in a human language. One line of 4GL code is equivalent to several lines of 3GL code. When they are implemented on microcomputers, some of these languages include graphic devices such as icons and onscreen push buttons for use during programming and when running the resulting application. Not all applications / projects are suitable for the use of 4GLs, but most projects are.
