How Data Flows Between System
Data flows between systems through Data Flow Diagrams or DFDs.
Data Flow Diagrams or DFDs is defined as a graphical representation of the flow of data through information. DFD is designed to show how a system is divided into smaller portions and to highlight the flow of data between these parts.
Here’s an example to demonstrate the Data Flow Diagram’s basic structure:
Components of a DFD:
Representation | Action performed |
---|---|
Square | Defines the source of destination of data |
Arrow | Identifies data flow and acts as a pipeline throughwhich information flows |
Circle/Bubble | Represents a process that transforms incoming data flow into outgoing data |
Open Rectangle | It is a data store or data at rest/temporary repository of data |
Note: Sender and Receiver should be written in uppercase always. Rather it is good practrice to use uppercaswe letter what so ever is placed in square box as per DFD conventions.
What is Systems Design – Learn System Design
Systems Design is the process of defining the architecture, components, modules, interfaces, and data for a system to satisfy specified requirements. It involves translating user requirements into a detailed blueprint that guides the implementation phase. The goal is to create a well-organized and efficient structure that meets the intended purpose while considering factors like scalability, maintainability, and performance.
Mastering Systems Design is crucial for anyone looking to build robust and scalable systems. Our comprehensive Systems Design course provides you with the knowledge and skills to excel in this area. Through practical examples and expert insights, you’ll learn how to effectively translate user requirements into detailed designs that can be successfully implemented.
