- fourth-generation language
A non-procedural programming language that requires less coding than lower-level languages. Command-line languages that come with operating systems and database management systems (DBMSs) are fourth-generation languages (4GLs), as are query languages and report writers. Any language with English-like commands that does not require traditional input-process-output logic falls into this category.
First-, Second- and Third-Generation Languages
First-generation languages are binary machine languages. Second-generation languages are machine-dependent assembly languages, and third-generation languages (3GLs) are high-level programming languages, such as FORTRAN, COBOL, BASIC, Pascal, C/C++ and Java.
