Physical Database Design Physical database design is the most detailed and technical level of the database design process. At this stage, designers make decisions about how the logical design will be implemented on a specific DBMS. Considerations include indexing, storage, performance optimizati...
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...
Re: Logical & Physical System Design in SysML and Sparx « Reply #1 on: June 06, 2022, 10:41:17 am » Hello pauldab,In my opinion,- Usually we do not describe connections (interactions) between sub blocks in the BDD. They should be described in IBD (of parent Block). In your...
The table below shows the difference between the three data models. An ER model is typically drawn at up to three levels of abstraction: Conceptual ERD / Conceptual data model Logical ERD / Logical data model Physical ERD / Physical data model While all the three levels of an ER model ...
