Systems design is basically the process of defining elements of a system including modules, architecture, components, interface, and data for a system based on a specific set of requirements. It can also refer to the process of defining, developing, and designing systems.
Systems design is basically the process of defining elements of a system including modules, architecture, components, interface, and data for a system based on a specific set of requirements. It can also refer to the process of defining, developing, and designing systems.
These designs have to satisfy the specific needs of a company or an organization.
As a system designer, you have to make use of all the different modeling languages for expressing the information and knowledge in the structure of a system. This system has to be defined by a consistent set of rules and definitions. It can also be defined in textual or graphical modeling languages.
There are different kinds of graphical modeling languages like the Unified Modeling Language, UML, Flowchart, Business Process Modeling Notation, and Systems Modeling Language.
There are also different types of design methods that you can make use of. They include Architectural Design, Logical Design, and Physical Design. By the way, if you can spend few bucks then I also suggest you to either join a dedicated system design platform like ByteByteGo by Alex Yu, author of popular System Design Interview – An insider's guide book. The ByteByteGo platform is the digital version of book and much more.
