Overview

If 4GLs held no advantages over 3GLs we would continue to use 3GLs.

You will always get debate over whether a 4GL is better than a 3GL but ultimately it will be the application that decides on which generation to use.

Advantages

Reduced costs

Less programming time
Better fit since user is involved.

Increased quality

They improve requirement analysis

Allows innovation

Alternative development approaches are possible
The traditional life-cycle approach to development is enhanced
Analysts, programmers & end users can use up-to-date tools & techniques

Increased productivity

Programmer productivity is increased
Faster systems development is possible
Smaller development teams are required

Ease of use

Offer ease of use facilities

Environment independence

Personal computers can play are part in the development process
Portability is aided

Non-procedural facilities

Able to specify what is to be done rather than how it is to be achieved.
