While the definition of 4GL has changed over time, it can be typified by operating more with large collections of information at once rather than focusing on just bits and bytes. Languages claimed to be 4GL may include support for database management, report generation, mathematical optimization, GUI development, or web development.
An interactive environment in which any 4GL statement may be typed and immediately processed (comparable to interactive tools like PHP or Perl) Relational database features, supporting lookup tables and the other elements of a normalized relational database; Powerful set-at-a-time operations under the control of simple imperative commands
SheerPower 4GL has several key features: It is free for hobbyists and non-profit organizations. Web scripting features make it fast and easy to develop dynamic web pages using SheerPower's BASIC-like syntax.

PROIV runs OS-independent application code in an OS-specific virtual machine, allowing a user application to run unaltered on different computing platforms. [5] As of August 2021, Zellis claims support for PROIV on Microsoft Windows (workstation and server), Red Hat Linux, IBM AIX, and Oracle Solaris; with Oracle, SQL Server, PostgreSQL, and IBM C-ISAM as the database backend.
"Ramis is a compromise 4GL relational database management system. It lacks SQL, a full programming language, good tech support, and the brute-force capabilities and sophistication of its competition. But it's remarkably easy to learn and use, comes with decent documentation, and performs the database basics."
It is specifically designed to run as a client on a network, connected to an IBM Informix database engine service. It has a mechanism for calling C Programming Language functions and conversely, to be called from executing C programs. The RDS version also features an interactive debugger for Dumb terminals.
