1. 4GLs are non-procedural and as such, program functions are not produced by the user but
the 4GL itself. Users simply request for the data processing result or output instead of
providing the detail physical and logic used. This helps to come up with applications
more quickly and cheaply with minimal errors. This aspect is critical in the case of
program development and results to increased programmers productivity.
2. 4GLs are problem oriented in that programs are designed to solve particular problems
using English like structures. Being problem oriented makes the language more
productive to specific applications. This is vital in the case of information system
development since it ensures quality and productivity of applications developed.
3. 4GLs enhance user creativity and productivity. Unlike procedural languages, 4GL tends
to promote user computing spirit and skills. User acceptance acknowledgement and
understanding will enhance reduction of technophobia: thus more quality and reliable
systems.
4. The system maintenance and flexibility is enhanced. 4GL facilitate a continuous process
of application development. The rigid requirement and the technical requirement
involved in system development life cycle is reduced. Change in user requirements can
always be incorporated in the systems design from time to time.
5. 4GLs enhance end user computing and so limiting the use of IT staff.
6. They help the organisation to top over creativity thus new information systems I will be
of higher quality.
7. 4GLs help in the diffusion of information technology throughout the organisation.
