Why is it beneficial and often necessary to have a structured design approach to computer program development?
Structured designing is clean. It is hard to imagine computer programming without thinking of it as being structured. Structure or a structured approach is built into the very concept of programming. By adding your own structure, you can, as a programmer, add order, power and usefulness to your program.
Modern programs are complex. The computers that manipulate them are very fast. A small mistake can go far in destroying value ( or maybe the entire human race! ). So be clear, be organised and be simple. Even the most complex tasks and algorithms can be implemented with utmost simplicity if you keep on breaking them down to logical levels.
A traditional approach, also known as structured system development, includes many variations which aim to develop information using structured and modular programming. On the other hand, an object oriented approach looks at the information system as a collection of objects that work together to accomplish a task.
The implication of using Database approach against the Traditional File approach is that, it is beneficial for most organizations. The implications can be listed as follows: 1. Potential for enforcing standards. 2. Reduced application development time. 3. Flexibility. 4. Availability of up-to-date information.
Unlike the behavioral approach, the piagetian approach focuses on the internal mental process. Under this approach, child development is subject to biological maturation and not environmental influences as believed by behaviorists. The approach also deals with development as children having to go through a process of cognitive development which is a defined order of stages.
A system development approach is a framework and guide of all the activities involved in system development, facilitates teamwork, sets expectation and communicates timelines, milestones & deliverables. An organization selects a system development approach based on their size, technological complexity and problem/opportunity the system will solve.
Top down and bottom up programming are two approaches or methodologies employed for designing structured programs in C. TOP DOWN APPROACH In 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 APPROACH The bottom down approach is just the opposite of the…
When building a house a structured modular approach is better than a haphazard approach Explain how a structured approach relates to developing programs and why using an organized approach is impor?
A structured approach when it relates to developing programs means that you are basically using one of three different structure types, which is known as single-alternative, dual-alternative, and multi-alternative structures. A structured approach relates to developing programs by meaning that when a program receives a statement it will continue to move one block at a time, and at the end of each block executing or skipping to the next block based on the answer that…
Structured decision making refers to the organized approach to making an informed decision. It can be done using lists or other organizational tools. Unstructured decision making usually refers to the spur of the moment decision making that requires little planning. Semi-structured decisions are made using less organization than structured decisions, but can also employ quick thinking and less planning.
