Many constraint-based languages, logic programming languages and some of the declarative languages are identified as 5GL. Because of this reason, 5GL are used in AI (Artificial Intelligence) research. This means that 5GL can be used to solve problems without a programmer. What are Fifth Generation Programming Languages?įifth generation programming languages (which followed 4GL) are programming languages that allow programmers to solve problems by defining certain constraints as opposed to writing an algorithm. Many fourth generation programming languages are targeted towards processing data and handling databases, and are based on SQL. Furthermore, 4GL rapidly expanded the number of professionals who engage in application development. By designing the languages according to the needs of the domains, it makes it very efficient to program in 4GL. This is achieved through the use of words (or phrases) that are very close to English language, and sometimes using graphical constructs such as icons, interfaces and symbols. 4GL surpassed 3GL in user-friendliness and its higher level of abstraction. 4GL preceded 3rd generation programming languages (which were already very user friendly). Explanation:What are Fourth Generation Programming Languages?įourth generation programming languages are designed to achieve a specific goal (such as to develop commercial business applications).
