Generally the overall design should be well thought out and reviewed before coding starts. Refer to our section on Design reviews to learn how to review your design. It is easier to try out different designs up front and discover problems early in the development cycle than to make a major design change after much of the code has been written. Your software design should include a description of the overall architecture.

This should include the hardware, databases, and third party frameworks your software will use or interact with. This is the big picture of what is running where and how all the parts will interact. Your software design should include all Application Programming Interfaces API that are used by your code or by external code that calls your code. The correct definition of these APIs is very important because once they are agreed to and used it is extremely difficult to change them without breaking lots of other peoples code.

This link describes how to design a good API. By software modeling we do not mean expressing a scientific theory or algorithm in software. This is what scientists traditionally call a software model. What we mean here by software modeling is larger than an algorithm or a single method. Software modeling should address the entire software design including interfaces, interactions with other software, and all the software methods.

Now that the user requirement has been well documented we move ahead towards specific and detailed planning. The next step is software design which promotes direct implementation and coding of the software to be developed.

We now know that software design is the place of the start of all amazing applications. One has ideas and goals which need to be realized in the form of application development.

Thus before the beginning of the building the basic architecture needs to be ready on paper for implementation. One should be able to weave the ideas in the head onto the paper. We tend to be excited to create software and start coding. Thus, the architecture will provide a smooth development process. These steps are iterated as a cycle and they may occur once or more times unless we arrive at the appropriate design which is finalized.

Software designing is though a very creative process but this cycle varies from designers to designers and firms to firms similar to the variations in user requirements yet we may be surprised to find some similarities in the designing process. From the above steps, we could see clearly that software designing is a creative process yet it is one of the most difficult tasks as it will decide the future of the final software.

This is a collaborative process and thus requires a lot of improvement and feedback at each step.
