In software development, when software has been forked or uses a chain of libraries/dependencies, upstream refers to an issue that occurs in software related to the chain. It is the direction that is toward the original authors or maintainers of software. It is usually used in the context of a version, a bug, or a patch.
Often, the version that will eventually become the next major version is called the development branch. However, there is often more than one subsequent version of the software under development at a given time. Often, the development branch is the trunk. Some revision control systems have specific jargon for the main development branch.
Low-level design (LLD) is a component-level design process that follows a step-by-step refinement process. This process can be used for designing data structures, required software architecture, source code and ultimately, performance algorithms.
In software development, downstream refers to a direction away from the original authors or maintainers of software that is distributed as source code, and is a qualification of a patch. For example, a patch sent downstream is offered to the developers or maintainers of a forked software project.
Software development is the process of designing and implementing a software solution to satisfy a user. The process is more encompassing than programming , writing code , in that it includes conceiving the goal, evaluating feasibility, analyzing requirements , design , testing and release .

Domain-driven design (DDD) is a major software design approach, [1] focusing on modeling software to match a domain according to input from that domain's experts. [2] DDD is against the idea of having a single unified model; instead it divides a large system into bounded contexts, each of which have their own model.
In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management .
