Abstract This paper will explain several differences between a logical network design and the physical design of a network. The design of a database is generally divided into three phases: Conceptual design. Logical architecture versus physical architecture. Physical modeling deals with the conversion of the logical, or business model, into a relational database model. Basically data modeling can fall into two types of categories: Physical modeling and Logical modeling. - Logical design includes all entities and the relationships between them. We use cookies to give you the best experience possible. May 11, 2005 This article definitely relates to the topic for this past week. The process may seem simple on this level and may require little consideration, but in fact, there are many areas of the network that need to be examined before the process of networking should be undertaken. At my current position, I am generally the end user of such networks. The pretty much covers it all! The logical data model defines the structure of the data elements and set the relationships between them. In week 4 and this past week (week 5) we learned about both Logical and Physical Database Design. For example, let’s say that the logical design shows a WAN connection as line between to buildings.When this is transformed into a physical design, that single line could expand into the connection, routers and other equipment at each end of the connection (Jim’s Weblog, 2005). THE DIFFERENCE BETWEEN LOGICAL DESIGN AND PHYSICAL DESIGN OF A NETWORK When comparing the logical and physical design of a network I visualize a carefully thought out plan created from start to finish by the individuals that would ultimately be using and maintaining it. hi well for starters a physical network design well, as the name implies, involves the physical connectivity of each of your hosts on the network. Logical design describes data as much as possible. Processes, roles, and even locations can show up in the logical design; however, the important aspect of the logical design is that it is part of the requirement set for a solution to a customer’s problem (Jim’s Weblog, 2005).Below is an illustrated example of a logical design of a network: Now that we have looked at the logical design, let’s take a look at the physical design of a network.
