System Design Strategy
System design => How and where you should put the program modules such that they
can be developed easily and also changed. Structured design techniques are designed
to manage the scale and complexity of software solutions for developers. They write
detailed instructions for the developers to help them with writing code, and how different
pieces of that code they should fit together in order to build up a program.
Software Engineering involves designing, creating, testing and maintaining software.
Important point: Software engineering is focused on creating reliable, performant and
maintainable software. System design is a very important step in software engineering,
and it must be conducted to decide on the architecture of system at first placement then
components interfaces modules as well data for that component.
System Design Strategy : It refers to the kind of strategy used in designing a software
system. Different strategies can be employed in the design of software systems, some
common ones;
1.Top-Down Design–[It is a method in which you take an overview of the whole system
and break it down into smaller components from there.]
2.Bottom-Up Design: The bottom-up approach designs individual components, and
when all parts have successfully been created the system is then built.
3.Iterative Design: This is the approach where you design and implement your system
in steps, with each step based on what was learnt from previous steps.
4.Composition: a journey in piecemeal design— You add just one tiny part of your
system and once you are satisfied with that dry, then move on to the next.
5.Agile Design: a Zagile method of design that takes an light, iterative approach to
designing where requirements and solutions evolve while building collaboration
between self-organizing cross-functional teams.
The design of a system is something that will act as an initial step for the solutions
related to the running process through it. Software systems design process can follow
two approaches. Level one will harp on what modules need to be a part of the system,
the specification for these modules and how do we want them connected; If you build a
precise system according to the design then that system meets your needs, its
requirements. Design process is not trying to get a design of the system. Rather,the
goal is some design that will work tolerably well subject to various requirements and
constraints including qualities of service offered by existing deployment platforms.
The system design strategy can be chosen based on the requirements of software to be
developed, size and complexity of the system etc. A well-designed system helps the
process of development and can improve software quality as managing it will also
become an easy task.
Importance of System Design Strategy:
1.Organize and Reaffirm all The Existing Code Before we go out if there are any
pre-existing code needs to be understood, organized, put together.
2. This age-old problem means that the project team will likely have to write some code
and generate custom programs in support of the application logic for system
requirements.
Advantages of using a System Design Strategy:
● It improves overall quality: A well architectured system increase the software clarity and
organized through structure.
● Reduce Time of maintenance: A good design can help the software could be mainted
and up-to-date easily because it make programmer easier to find each part code thank
to clear diagram between component.
● Increased efficiency: When done properly, it can enhance the efficiency of the software
by providing an organized structure to reduce complexity in code.
● A good communication: By designing the system nicely you can communicate
stakeholders better as it provides a neat and organized structure of software that makes
easier for any stakeholder to clear same page in design perspective.
● Rapid Development: A good design system can accelerate the development process —
it offers organised software blueprint, helps developers to understand what needs to be
done quickly and deliver it.
Disadvantages of using a System Design Strategy:
● Complexity. Designing a system often takes weeks or months for large-scale,
complex systems since lots of documentation and analysis are required.
● Resistance to change: Given the structured step-by-step nature of a process, it
may be difficult to amend an existing design in terms of flow because this must
involve alterations at mechanical level and also due to potentially heavy
documentation.
