three basic approaches which are used in developing application software
The three approaches which are utilized in developing application software are:
- Top-down approach
- Middle-out approach
- Bottom-up approach
Top-down approach:
The top-down approach is basically the standard procedure of going from high-level abstraction and logical designs to the physical application of the system. It is best applied to classical systems engineering projects where the team is asked to develop an unprecedented system.
Most of the system developers want this kind of project as it enables them to make the system from scratch and hardly consists of stakeholder-imposed constraints.
In this approach, the projects will have a focus on technology research and the creation of new techniques and components to implement the solution.
This is the most popular approach for developing application software.
