Below is an example of a logical schema: A physical data model or physical schema is a representation of an implementation design; it defines data abstraction within physical parameters.

A logical data model is required before you can even begin to design ... Of course, there are many other decisions that must be made during the transition from logical to physical. For example, each ...

This type of model is used to design the database. The physical data model contains all the specifics about how the logical model will be implemented. This model format includes table names ...

For example, a relational table may represent ... this process is called JOINS. The physical data model specifies how physical structures such as databases will store data, including formats ...

The requirements for a logical and physical database vary by size and design parameters. A logical database must be able to access and identify all files within the storage system to operate ...

A good example of this is encryption and decryption of data for secure transmission ... routing capabilities. Layer 1: Physical At the bottom of our OSI model we have the Physical Layer, which ...
