External Level
The level that is considered closest to the end-users is the external level. This level focuses on the user's perspective and provides a simplified and intuitive interface for interacting with the database. It is designed to meet the specific needs and requirements of the end-users, making it more user-friendly and accessible.
Key features of the external level:
- User-focused: The external level is designed to cater to the specific needs and requirements of different types of end-users. It takes into consideration their knowledge, skills, preferences, and tasks to provide a user-friendly interface.
- Simplified view: The external level presents a simplified and intuitive view of the database, abstracting the complex underlying structures and technical details. This allows end-users to interact with the database without having to understand the complexities of the underlying data model.
- Customization: The external level allows for customization and personalization based on the individual user's requirements. It may provide features like customizable forms, reports, and queries, allowing users to define their own views and extracts from the database.
- Language and interface: The external level often provides a high-level language or a graphical user interface (GUI) that simplifies the interaction with the database. This helps users to easily perform tasks such as querying, updating, and retrieving information from the database.
- Security and privacy: The external level may also incorporate security measures to protect sensitive data and ensure privacy. It may include features like user authentication, access control, and encryption to safeguard the database and user information.
Example:
For example, in a banking system, the external level may provide a user-friendly interface for customers to perform tasks such as checking their account balance, making transactions, or generating account statements. The interface may have functionalities like dropdown menus, buttons, and forms that simplify the interaction with the database.
Overall, the external level plays a crucial role in bridging the gap between the complex underlying database structures and the end-users, making it easier for them to interact with and utilize the database effectively.
