difference between physical and logical data flow diagrams.
Top down Program Design : Begins the design with main or top-level module, and progresses downwards to the lowest level modules or subsystem Bottom down Program Design : Begins the design with the lowest level modules or subsystems, and progresses upward to the main program, module or subsystem.
"Face" means any/every flat surface that the solid has. "Base" is the face that it happens to be resting on right now. But if you want to, you can pick it up, turn it, and set it down on a different face. So the 'base' and 'top' can change, but they're all faces.
what are the pros and cons of the top down approach
Nothing. Top-down approach is a way of human thinking.
top level
The top-down approach in problem-solving starts with a broad overview and then breaks it down into smaller, more specific parts. This is different from the bottom-up approach, which begins with the details and gradually builds up to a larger solution.
what is a learning organization? Is this approach to strategic management better than the more traditional top-down approach in which strategic planning is primarily done by top management?
Top-down
the dfd which independent view of the system is called logical dfd
Top down and bottom up programming are two approaches or methodologies employed for designing structured programs in C.TOP DOWN APPROACHIn a top down approach a program(structured) is designed by using the top down methodology as follows..First the overall structure of the program is designed and it is defined and then it is followed by the designing of individual functions..BOTTOM DOWN APPROACHThe bottom down approach is just the opposite of the top down approach..ie, the program is designed by first designing the individual functions followed designing of overall program structure
When you write the routine for functions and sub programs and go for the main function, it is called the bottom up approach. If you do the process in reverse it is called the top down approach..
A top-down approach starts with a broad perspective and breaks it down into smaller details, while a bottom-up approach begins with specific details and builds up to a broader perspective. Top-down is more strategic and efficient, while bottom-up is more detailed and thorough. Both approaches have their strengths and weaknesses, and the best approach depends on the specific situation.
