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 around the needs of the business‚ not the network‚ although the needs of the business are used to establish the needs of the network. Logical modeling involves gathering information about business processes‚ categories of data‚ and organizational

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

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. Like many areas in Information Technology‚ Network Design cannot be taken likely. All of the necessary steps like those of the SDLC process must be done step-by-step in order to minimize unnecessary costs‚ downtime and loss of

Difference between Logical & Physical Design of a Network When we look at the differences between logical design and physical design of a network it is easy to think of it as the logical as the functional part and physical as the seeing it part. With that stated there is more to this than just the functional and seeing parts. In order to understand the differences from one to the other‚ we need more information. In the following paragraphs I will try to outline what makes up the differences between

Logical Design Logical design takes each piece of conceptual design and assigns it to a specific logical role within architecture. For infrastructure projects‚ the architecture might be a series of block diagrams showing networks‚ service components‚ and network connection elements. Application architecture is typically broken down into at least three levels: presentation‚ business‚ and data level. Because this is a migration project‚ the team should document the existing logical design as well

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
