Question
Chapter 9, Problem 13RQ
Program Plan Intro
- The second stage of DBLC (Database Life cycle) is the database design.
- DBLC is a sequential process which is used to trace the history of the application that is present within the
information system . - The design phase consists of three stages and they are:
- Conceptual design
- Design a database that is independent of software and physical details.
- Logical design
- The main design goal is to make an enterprise wide database.
- Design a database that is based on the specific data model but independent of physical details.
- Physical design
- It is used to determine the storage capabilities of the data in an organization and its access characteristics.
- It ensures the integrity, security and performance.
- Conceptual design
