Today it is mostly done in a team. Software engineering can broadly be split into the following:
- Requirements say what the software should do. Note that the requirements can change over time.
- Software design is usually done on paper. It says what the different components of the software are, and how they interact.
- When the design phase is done, engineers program the software in a phase known as implementation.
- At the end of implementation, engineers test their code to see if its components meet the requirements.
Programming is definitely the blood of almost all software. And just like calculus is to engineering, programming is to software engineering.
There are four generic phases in Software Engineering which are Analysis, Design, Coding and Testing.
- implement system routines
- construct / traverse data structures
- distill large data sets to single values
- transform one data set to another
- language familiarity
- core libraries
- performance issues
- readable, well-written, and efficient code
Algorithm design and analysis
- complexity analysis
- sorting and hashing, searching
- large amounts of data
- feature sets
- class hierarchies
- designing a system under certain constraints
- simplicity and robustness
- classes of NP-complete problems
- listening and comprehension
- asking the right questions
- don't use brute force solutions
- don't assume things
- find multiple solutions and choose the best
- be open to new ideas and ways of solving the problem
- ask questions to move to a more complex answer
- discrete math
