System design is the process of defining the components, architecture, and interfaces of a system to meet specific business requirements. It involves steps such as logical design, physical design, construction design, and system testing. The logical design organizes data, while physical design translates this into a layout, and testing evaluates the system's compliance with requirements.

3. What is System Design
Systems design is the process of defining
elements of a system like modules,
architecture, components and their
interfaces and data for a system based on the
specified requirements. It is the process of
defining, developing and designing systems
which satisfies the specific needs and
requirements of a business or organization

6. Phases In System Design

7. Logical Design
A logical design is a conceptual, abstract design.The
process of logical design involves arranging data into a
series of logical relationships called entities and
attributes. An entity represents a chunk of
information. In relational databases, an entity often
maps to a table.

8. Physical Design
The physical design is the process of
transforming a circuit description into
the physical layout, which describes the
position of cells and routes for the
interconnections between them.

9. Construction Design
CoCAD, or computer-aided design, refers to any software used by
architects, engineers, or construction managers to create precision
drawings or illustrations of new buildings as either two-dimensional
drawings or three-dimensional model construction Design.

10. System Testing
System Testing (ST) is a black box testing technique performed to
evaluate the complete system the system's compliance against specified
requirements. In System testing, the functionalities of the system are
tested from an end-to-end perspective.
