In the physical design, you look at the most effective way of storing and retrieving the objects. Your design should be oriented toward the needs of the end users.

What is the basic architecture of a computer system?

The different components in the Computer System Architecture are Input Unit, Output Unit, Storage Unit, Arithmetic Logic Unit, Control Unit etc. … A diagram that shows the flow of data between these units is as follows − The input data travels from input unit to ALU.

What is logical architecture diagram?

Level 1: Basic Promises Fulfilled – Using a detailed data dictionary and glossary, users develop a basic understanding of the data. The system provides an integrated glossary that can be queried and is tightly integrated with its output; users can easily navigate between data and its definition.

What is physical and logical network diagram?
