List and briefly explain the three steps performed during the physical design stage.

Program Plan Intro

Physical design:

The process of determining the organization’s data storage and the data access characteristics of the database in order to ensure its security and integrity constraints and performance. Physical design acts as a technical job because it does not affects the accessibility of the storage device but also the performance of the system.

Explanation of Solution

Steps involved in physical design:

  • Define data storage organization
  • Define integrity and security measures
  • Determine performance measurements.

Data storage organization:

  • It helps to determine the data volume by which one can calculate the storage space needed to reserve the database.
  • The data usage patterns can be determined by knowing the frequent insertion, updating and deletion.
  • Determining the location and physical storage organization for each table and also identifying the types of indexes used for each table.

Integrity and security measures:

  • This step ensures the creating users and security groups. A designer should know the type of users and group of users to properly ensure database security...
