Since physical ERD and logical ERD represent the business requirement and database schema respectively, comparing physical and logical ERD helps to find out the differences between them, thus confirming the database is exactly following the initial business requirements regardless of the changes. Visual ...
What’s the difference between a logical DFD and a physical DFD? A logical DFD focuses on the business and business activities, while a physical DFD looks at how a system is implemented. So while any data flow diagram maps out the flow of information for a process or system, the logical...

Find out how to create logical data models in Vertabelo! If you have some experience with physical diagrams, this will be as easy as pie. There are three different levels of data models: conceptual, logical, and physical. Of these, the conceptual model is the most abstract, and the logic...
Take a quick interactive quiz on the concepts in The Difference Between Logical & Physical Data Flow Diagrams or print the worksheet to practice offline. These practice questions will help you master the material and retain the information.
The main difference I see from this in practice is that many data models that are described as logical actually have some level of denormalization in them, particularly where change over time is involved. A logical data model might relate to a physical data model, but this is not the only ...
What is the difference between a logical drive and a physical drive? A logical drive is a virtual entity that is created within a physical drive. It represents a partition or section of the physical drive and is treated as a separate storage space by the operating system. On the other hand...
