About Logical Connection

Data flow diagrams DFDs are categorized as either logical or physical.A logical DFD focuses on the business and how the business operates.It describes the business events that take place and the data required and produced by each event. On the other hand, a physical DFD shows how the system will be implemented.Here are the main differences between logical and physical DFD

Data flow diagrams are composed of four elements external entities, processes, data stores and data flows. But the elements represent different perspectives in logical DFDs than in physical DFDs. For example, in logical DFDs, the processes are business activities in physical DFDs, the processes are software programs, manual procedures or

A logical data flow diagram is a visual representation of how data flows within a system, focusing on the logical relationships between processes, data sources, and data destinations. It provides a high-level view of the system's data flow and helps to identify the data inputs, outputs, and processes involved in the system.

Logical DFD and Physical DFD are two types of data flow diagrams used in system analysis and design. The main difference between the two lies in their level of detail and abstraction. A Logical DFD focuses on the logical flow of data within a system, representing the processes, data stores, and data flows without considering any specific

The physical data flow diagram below shows certain details not found on the logical data flow diagram above. Developing Logical Data Flow Diagrams. To develop such a diagram, first construct a logical data flow diagram for the current system. There are a number of advantages to using a logical model, including Better communication with users.

The physical data flow diagram for a grocery store offers a detailed view of the system's implementation. It includes specifics such as the UPC code, bank details, POS terminals, inventory database, and network connections. This diagram provides a concrete representation of the technical components involved in the store's operations.

There are different types of logical diagrams, each with its own purpose and conventions. Some common examples include network diagrams, flowcharts, data flow diagrams, and entity-relationship diagrams. Each type of diagram has its own set of symbols and rules for representing specific elements and connections.

A logical diagram is a visual representation of a system or process that demonstrates the flow of information, data, or operations. It is used to illustrate the logical relationships and connections between various components or elements, helping to understand and analyze the functionality and structure of a system.

Logical and physical data flow diagrams are the two classifications of data flow diagrams. Physical data flow diagrams illustrate how a system will be implemented. It is depicted in the manner to ensure the organization's goals are met. They smooth the manual processes and present them in a structured format for effective communication.

It represents the flow of data and the logical connections between devices. This diagram provides a high-level view of the network architecture and helps administrators understand how data is transmitted and processed within the network. In summary, while physical network diagrams showcase the physical components and their connections
