Advantages of system flowchart over program flowchart?

Answer 1

The difference between a program flow chart and a system flowchart is that a program flowchart is for a single program. A system flowchart is designed for an entire system with each box representing a process.

Answer 2

A system flowchart might show the programme in a larger context, so that the programme sources and uses of data, and data exchanges between programmes become clear.

A programme flowchart details the logic of operations performed on the data by a single programme.

Therefore, if a customer number has already been checked by another programme in the system -- as documented in the system flowchart -- and verified that it is a valid customer number, the single programme may not need to validate the customer number, which would be detailed in the programme flowchart.

However, depending on the organization you're working with, different definitions of these terms might apply.

Answer 3

it only really ocvers a micro view- would be difficult to map an entire multimillion dollar industy complex and clumsy model alterations and modifications mean that you have to redraw the entire process essential details can be lost in technical details of how its done oversimplifies timeconsuming Then good things about the model are: it simplifies the process, allowing you to identify and eliminate non value adding processes,as well as delays, bottlenecks and failpoints. It allows you to streamline and improve the entire process whilst analysing it from end to end.

ADVANTAGES OF USING FLOWCHARTS

The benefits of flowcharts are as follows:

1. Communication: Flowcharts are better way of communicating the logic of a system to all concerned.
2. Effective analysis: With the help of flowchart, problem can be analysed in more effective way.
3. Proper documentation: Program flowcharts serve as a good program documentation, which is needed for various purposes.
4. Efficient Coding: The flowcharts act as a guide or blueprint during the systems analysis and program development phase.
5. Proper Debugging: The flowchart helps in debugging process.
6. Efficient Program Maintenance: The maintenance of operating program becomes easy with the help of flowchart. It helps the programmer to put efforts more efficiently on that part

LIMITATIONS OF USING FLOWCHARTS

1. Complex logic: Sometimes, the program logic is quite complicated. In that case, flowchart becomes complex and clumsy.
2. Alterations and Modifications: If alterations are required the flowchart may require re-drawing completely.
3. Reproduction: As the flowchart symbols cannot be typed, reproduction of flowchart becomes a problem.
4. The essentials of what is done can easily be lost in the technical details of how it is done.

Answer 5

Let me make this simple for you. How can you get four by adding 2 numbers. Their are infinite possible ways. If you think that 2+2 and 3+1 are the only ways you are wrong. 2.8+1.2 is also an option. So choosing 1 of these ways is what we call a computer algorithm.

The flowchart is basically how you want to design the program to do a specific operation. Now you can do this in many possible ways. But you choose one of these ways and design the idea or the structure of the program in one of these ways through flowchart. Now you shape this idea of yours through blocks of codes you call GWBASIC. You can do it in any language as flowcharts are language independent.

Answer 6

The difference is exactly the same as the difference between civil engineering blueprints for a suspension bridge and the actual suspension bridge after it has been built.

Answer 7

A program is the computer code that performs some task. A flowchart is a graphical representation of the functions of the program from START to END.
