Here are the most important subjects for software engineering, with brief explanations:
1.Object oriented analysis & design
: For better maintainability, reusability and faster development, the most well accepted approach, shortly OOAD
and its SOLID
principals are very important for software engineering.
2.Software quality factors
: Software engineering depends on some very important quality factors
. Understanding and applying them is crucial.
3.Data structures & algorithms
: Basic data structures
like array, list, stack, tree, map, set etc. and useful algorithms
are vital for software development. Their logical structure should be known.
. Big-O notation: Big-O notation indicates the performance of an algorithm/code section. Understanding it is very important for comparing performances.
is the universal and complete language for software design & analysis. If there is lack of UML in a development process, it feels there is no engineering.
6.Software processes and metrics
: Software enginnering is not a random process. It requires a high level of systematic and some numbers to monitor those techniques. So, processes
: Design patterns
are standard and most effective solutions for specific problems. If you don't want to reinvent the wheel, you should learn them.
8.Operating systems basics
: Learning OS
basics is very important because all applications runs on it. By learning it, we can have better vision, viewpoints and performance for our applications.
9.Computer organization basics
: All applications including OS requires a hardware for physical interaction. So, learning computer organization
basics is vital again for better vision, viewpoints and performance.
is related with computer organization, OS and the whole information transfer process. In any case we will face it while software development. So, it is important to learn network basics.
: Requirement analysis
is the starting point and one of the most important parts of software engineering. Performing it correctly and practically needs experience but it is very essential.
is another important part of software engineering. Unit testing
, its best practices
and techniques like black box, white box, mocking, TDD
, integration testing etc. are subjects which must be known.
: Library (JAR, DLL etc.) management, and widely known tools (Maven, Ant, Ivy etc.) are essential for large projects. Otherwise, antipatterns like Jar Hell
: Continuous integration
brings easiness and automaticity for testing large modules, components and also performs auto-versioning. Its aim and tools (like Hudson
etc.) should be known.
15.ORM (Object relational mapping)
and its widely known implementation Hibernate framework is an important technique for mapping objects into database tables. It reduces code length and maintenance time.
16.DI (Dependency Injection)
: DI or IoC
(Inversion of Control) and its widely known implementation Spring framework makes life easy for object creation and lifetime management on big enterprise applications.
17.Version controlling systems
tools (SVN, TFS, CVS etc.) are very important by saving so much time for collaborative works and versioning. Their logical viewpoint and standard cammands should be known.
by extracting strings into external files is the best way of supporting multiple languages in our applications. Its practices on different IDEs and technologies must be known.
: Understanding architectural design patterns
(like MVC, MVP, MVVM etc.) is essential for producing a maintainable, clean, extendable and testable source code.
20.Writing clean code
: Working code is not enough, it must be readable and maintainable also. So, code formatting
and readable code
development techniques are needed to be known and applied.
