| Lesson 4 | Application approach to database design |
| Objective | Describe the application approach to DB Design |
The second approach to database design is to focus on the application in which the data will be stored and viewed.
This approach is often used when data must be presented in a specific format.
Designers create complex applications (or use pre-existing applications) to present and organize the data.
Bottom-up design
This approach is often used when data must be presented in a specific format.
Designers create complex applications (or use pre-existing applications) to present and organize the data.
The application approach is a bottom-up design because it focuses primarily on how data will be viewed (either on screen or in
reports or other special documents) and only secondarily on how it will be organized.
In other words, the database is designed to fit the application.
Although the application approach is useful in some situations, the subject approach to database design is the most common and the one on which this course focuses.
The next lesson examines the overall architecture of databases.
