Fourth-Generation Programming Language: Applications
built 656 days ago
Fourth-generation programming languages are successor to the third generation programming languages. The third generation programming languages are difficult to use for ordinary users. There for 3GL development methods can be slow and error prone. It became clear that some applications could be developed more rapidly by adding a higher-level programming language and methodology which would generate the equivalent of very complicated 3GL instructions with fewer errors. Fourth-generation programming languages are designed to reduce programming effort, the time it takes to develop software, and the cost of software development.

WinDev uses its own fourth-generation programming language, WLanguage. The tools enables you to predetermine a set of your own standard forms and algorithms that can be used in an automated fashion to quickly generate applications (RAD). The source code is precompiled and interpreted at run time like Visual Basic, Java or C#. This makes the executable program independent from the operating system and allows dynamic compilation as well as instant testing during development. WinDev was originally conceived as a CASE tool for writing Windows applications but now WinDev applications can ... be targeted to run on Linux.

[G]eneration language (2GL)... known as second-generation programming language, usually refers 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). The language is specific to and dependent on a particular processor family and environment. Since it is the native language of a processor it has significant speed advantages, but it requires more programming efforts and is difficult to use effectively for large( or wide) applications.

Collections work like the set, queue, stack, and hash table data structures found in most third-generation programming languages. Collections can store instances of an object type, and they can ... be attributes of an object type. Collections can be passed as parameters. Hence, they can be used to move columns of data into and out of database tables or between client-side applications and stored subprograms. Collection types can be defined in a PL/SQL package and can be used across many applications.

PV-WAVE, from Visual Numerics, Inc., is an array oriented fourth generation programming language used by engineers, scientists, researchers and business analysts to build and deploy visual data analysis applications. These applications let users manipulate and visualize complex or extremely large technical datasets to detect and display patterns, trends and anomalies along with other vital information. In the latest release of PV-WAVE, the VTK toolkit has been integrated to make all of its functionality available to PV-WAVE users. The two products complement each other exceptionally well. PV-WAVE excels at data access, data manipulation, numerical algorithms, data filtering, user interface development and many interactive 2D graphical tasks while the Visualization toolkit provides the tool for creating complex, powerful 3D visualizations. Together they provide a simple and fast way to build tools for Visual Data Analysis.

SPSS is a fourth generation programming language with applications for statistics, graphs, and reports. Although SPSS initially was designed for statistical analysis in academia, it now includes tools for commercial and government settings. Applications include surveys, marketing and sales analysis, data mining, quality improvement, and statistical research of all types.
