The main domains and families of 4GLs are: database queries, report generators, data manipulation, analysis and reporting, screen painters and generators, GUI creators, mathematical optimization, web developmentand general purpose languages. Today high level language or fourth generation language is the result of extensive research in developing programming to make programming more efficient and it is used universal. Listed below are advantages of fourth generation computer: (1) Practically maintenance -free. They also used input and output devices like mouse, printers, and keyboards for better performance. It is operated with the mnemonics and its parameter. In other words, instead of coding, the developer uses table-driven algorithm programming (see also. fourth-generation language (4gl), computer programming language that is intended to be easier for users than machine languages (first-generation), assembly languages (second The Disadvantages of Assembly Language. 1. In 1981 IBM introduced itsfirst computer for the home user, and in 1984 Apple introduced the Macintosh. Extract data from files or database to create reports in a wide range of formats is done by the report generator tools. The advantage of third-generation language 3GLs. Instead of using code, the developer defines their logic by selecting an operation in a pre-defined list of memory or data table manipulation commands. They are multitasking and multiprogramming with the time-sharing concept. It comprises a set of instructions that are used to produce various kinds of output. A Fourth Generation (Programming) Language (4GL) is a grouping of programming languages that attempt to get closer than 3GLs to human language, a form of thinking, and conceptualization and are easier to use than 3GLs. Each of the programming language generations aims to provide a higher level of abstraction of the internal computer hardware details, making the language more programmer-friendly, powerful, and versatile.
