Abstract This paper will explain several differences between a logical network design and the physical design of a network. Most people tend to think of it as the logical meaning the functional part and the physical as the seeing it part. With saying that one must understand that there is more to the logical and physical design of a network than just the functional and seeing parts. In order for one to understand the differences of how the two operate and work from one to the other‚ one would

for a proposed network‚ they must be modeled. Models are created to visually represent the proposed network so that business requirements can easily be associated with network objects to ensure that all requirements have been completely and accurately gathered. Basically data modeling can fall into two types of categories: Physical modeling and Logical modeling. Logical modeling deals with gathering business requirements and converting those requirements into a model. The logical model revolves

The Physical Data Model (PDM) describes how the information represented in the Logical Data Model is actually implemented‚ how the information-exchange requirements are implemented‚ and how the data entities and their relationships are maintained. There should be a mapping from a given Logical Data Model to the Physical Data Model if both models are used. The form of the Physical Data Model can vary greatly‚ as shown in Figure 31. For some purposes‚ an additional entity-relationship style diagram

Difference between Logical Design and Physical Design NTC 410 August 8‚ 2006 Understanding network topology can tell one a great deal about installing or expanding a network. At its basic level‚ the topology of a network refers to the way in which all its pieces have been connected. That is‚ it refers to the layout of the computers‚ printers‚ and other equipment hooked to the network (TechTarget 2006). Because cables connect computing resources together for a network‚ network ’s topology

which a task can start and finish” (Wysocki‚ 2009). This process is known as the “forward pass through the network diagram” (Time management). Also the “LS to LF procedure “which consists of the latest times at which a task can start and finish without delaying the completion date of the project” is calculated (Wysocki‚ 2009). This process is known as the “backward pass through the network diagram” (Time management). Both the ES to FS and LS to LF procedures were calculated based on all the dependencies

Transforming Logical Data Models into Physical Data Models Susan Dash Ralph Reilly IT610-1404A-01 According to an article written by Tom Haughey the process for transforming a logical data model into a physical data model is: The business authorization to proceed is received. Business requirements are gathered and represented in a logical data model which will completely represent the business data requirements and will be non-redundant. The logical model is then transformed into a first cut physical model
