The difference between logical and physical process models are that logical process models are models that give a broad description of how the processes of the model work, without indicating how they are conducted. For example a logical process model won’t tell you where the information comes from, whether it is from paper or from the web. Physical process models fill in all the little details left out of the logical process model. This model provides the necessary information to build the system.
The distinction between a logical process model and a physical process model is really basic and easy to understand. The physical process model entails all the details that are left out of the logical model which in turn are essential assets to building the system. However, the logical process model is what describes the process of the system but it is hard to distinguish whether or not one piece of information is taken from one place or another. Those details are what make up the physical process model. When logical process models are done first, which is key to a successful system and should always come before the physical process, allows analysts to focus more on how the business is to be run first. That being said, it avoids the distraction of the implementation details that are provided with the physical process.
Logical models are models that describe a process without any suggestions of how they are to be conducted. Physical models are models that provide the intended information that is needed to build the system. Logical models should be used first in a business because this model shows how the business should run, without and detailed information distractions. In a sense, logical models are primary for a layout of a model and the physical model provides much more detailed information on the system.
Physical models are created to show implementation details and explain how the final system will work. These details include references to actual technology, the format of information moving through processes, and the human interaction that is involved. The logical models do not contain any indication of how the system will actually be implemented when the information system is built, they simply state what the new system will do.
Logical Process Models describe processes as they should go without describing in detail exactly how they are conducted where as Physical Process Models refine the physical details and define the information which is ultimately needed to build the system.
There are several differences between logical modeling and physical modeling. With logical modeling you will be dealing with gathering business requirments and converting them into a model. This revolves specifically around the needs of the business and not necessarily the database. This is not saying that you wont be using the needs of the bussiness to form the database. Once all of the information is collected, the company can then start making diagrams, and reports.
Physical modeling involves the actual design process ofa database. In order to make this database you will be using the requirments determined by the logical modeling. Physical modeling will deal with the conversion of the logical, or business model into a relational database. One thing to remember is that when you start a physical model, all the objects are being defined at the schema level.
