pl:4GL A fourth-generation programming language (or 4GL) is an application-specific programming language.
The first three generations were developed fairly quickly, but it was still frustrating, slow, and error prone to program computers, leading to the first "programming crisis", in which the amount of work that might be assigned to programmers greatly exceeded the amount of programmer time available to do it.
Thus were born report-generator languages, which were fed a description of the data format and the report to generate and turned that into a program which actually contained the commands to read and process the data and place the results on the page.

 Fifth-generation programming language - Wikipedia, the free encyclopedia
A fifth-generation programming language (abbreviated 5GL) is a programming language based around solving problems using constraints given to the program, rather than using an algorithm written by a programmer.
While fourth-generation programming languages are designed to build specific programs, fifth-generation languages are designed to make the computer solve the problem for you.
In the 1990s, fifth-generation languages were considered to be the wave of the future, and some predicted that they would replace all other languages for system development, with the exception of low-level languages.

 Second-generation programming language - Wikipedia, the free encyclopedia
A second-generation programming language is a term usually used to refer to some form of assembly language.
Unlike first-generation programming languages, the code can be read and written fairly easily by a human, but it must be converted into a machine readable form in order to run on a computer.
The conversion process is simply a mapping of the assembly language code into binary machine code (the first-generation language).

Mesa is a programming language developed at Xerox PARC that was used to program the Xerox Alto (one of the first personal computers with a graphical user interface), and later the Xerox Star workstations, and later the GlobalView desktop environment.
In computer science, a programming language is type safe when the language does not permit the programmer to treat a value as a type to which it does not belong.
In computer programming, operator overloading (less commonly known as operator ad-hoc polymorphism) is a specific case of polymorphism in which some or all of operators like +, = or == are treated as polymorphic functions and as such have different behaviours depending on the types of their arguments.

 Low-level programming language
The second-generation programming language or 2GL is Assembly Language.
Note that high-level versus low-level is a property; a Java programmer would consider C to be a low-level language while assembly language programmer would consider C to be a high-level programming language.
The word "low" does not imply the language is inferior to high-level programming languages but rather refers to the lower of abstraction.

 The ALGOL Programming Language
ALGOL was the first second-generation programming language and its characteristics are typical of the entire generation.
Overall, ALGOL is considered to be perhaps the most orthogonal programming language, meaning it has a relatively small number of basic constructs and a set of rules for combining those constructs.
ALGOL (ALGOrithmic Language) is one of several high level languages designed specifically for programming scientific computations.

 Programming Language Comparison
Thus, while object-oriented languages strive to remain at a fairly high level of abstraction, to be suitable for systems programming a language must provide such features or relegate such low-level tasks to a language with which it can interact.
Nearly every language to come along since C was first introduced provides such integration with C. This allows high level languages to remain free of the low level constructs that make C great for systems programming, but add much complexity.
Generational garbage collection works in a similar fashion to mark and sweep garbage collection, except it capitalizes on the statistical probability that objects that have been alive the longest tend to stay alive longer than objects that were newly created.

Language features interact in subtle ways---if every developer with a good idea is allowed to mess with the language, surely the result will be a syntactic and semantic mess.
Well-nested goto statements become structured programming's conditionals and loops; records that are only ever accessed through companion functions become objects; functions that are identical except for data types become generics, and so on.

In the computer industry, these abbreviations are widely used to represent major steps or "generations" in the evolution of programming languages.
1GL or first-generation language was (and still is) machine language or the level of instructions and data that the processor is actually given to work on (which in conventional computers is a string of 0s and 1s).
4GL or fourth-generation language is designed to be closer to natural language than a 3GL language.

 What is cobol?  Find out about this programming language years ahead of it's time
However by modern standards for programming language definition, it had serious flaws, notably verbose syntax and lack of support for local variables, recursion, dynamic memory allocation, and structured programming.
While this idea seems reasonable on its face, in practice the most difficult task in programming is reducing a complex computation to a sequence of simple steps, not specifying those steps with a particular language.
A motivation of COBOL's design was to make programming easier by making the language as English-like as possible.

Second, note that, although this example uses the Singleton pattern in several places because it is well known and succinct, if you ever find yourself writing a widely used framework, you should certainly not use the Singleton pattern in its API.
While aspect-oriented programming (AOP) offers a powerful means of modularizing programs, and a robust, feature-rich implementation for the Java platform is available in AspectJ, AOP is not yet in the average Java programmer's toolbox.
In this report on the new generation of AOP frameworks, Dave Schweisguth contrasts the new with the old, explains where the new features fit in, and looks to the future of AOP on the Java platform.
