Being good at problem-solving is one thing but to take your career to the next level, one must know how complex software projects are architected. Software design patterns provide templates and tricks used to design and solve recurring software problems and tasks. Applying time-tested patterns result in extensible, maintainable and flexible high-quality code, exhibiting superior craftsmanship of a software engineer. Being well-versed in knowledge of design patterns allows one to spot brittle and immature code from miles away. The course goes to great lengths to lay bare the esoteric concepts of various design patterns before the reader and is replete with real-world examples and sample code. The readership for this course is expected to be familiar with some object orientated language. The course examples and snippets are written in the Java language but folks with experience in other OOP languages should easily be able to follow the discussion and code intent.
What is software engineering?#
Software engineering refers to designing, developing, and testing the software programs and applications widely used in real life. Software engineers often serve as the individuals responsible for developing software and conducting extensive testing and quality assurance checks. Their primary objective is to guarantee the effectiveness and efficiency of newly developed software when deployed in real-world applications.
Key concepts and practices in software engineering include the following:
Requirements analysis: Understanding, defining, and documenting the needs and constraints of a software system.
Design: Creating a blueprint for the software, detailing system architecture, component design, data structures, user interfaces, etc.
Implementation or coding: Translating the software design into source code using a specific programming language.
Testing: Verifying and validating that the software meets the specified requirements, works as expected, and is free (or almost free) of defects.
Maintenance: Ongoing support of a software system to correct errors, meet new requirements, or handle changes in the environment.
Software process and lifecycle models: Structures used to define the phases and their order, such as Waterfall, Agile, Scrum, and DevOps.
Quality assurance: Ensuring that the software meets the required quality standards.
Software metrics and measurement: Quantitative means to gauge or compare system characteristics or the process used to develop or maintain the system.
Risk management: Identifying, analyzing, and mitigating potential issues that could negatively impact the success of a software project.
