FOURTH GENERATION TECHNIQUES (4GT)
This model used fourth-generation technologies to develop software linearly. It has the same stages as in the linear sequential or waterfall model. CHARACTERISTICS: Use of software tools that allow software engineers to specify software characteristics at a higher level. The tools generate codes based on specifications. More time in design and testing increases productivity. Tools may not be easy to use, and codes generated may not be efficient. ADVANTAGES: More advanced technologies are used. The software will be more adaptable to future technological changes. Developers find ease in application generation. Time and cost-efficient. DISADVANTAGES: Much more qualified and experienced developers are needed. We have to depend on third parties to support our system. Codes generated may not be easy to use. Tools may not be easy to use
