Study Notes
Introduction to Database Management System
- A Database Management System (DBMS) is a collection of programs designed to manage database structures and control access to stored data.
- The DBMS acts as an intermediary between users and the database, facilitating data operations.
- Database structures are stored as files, which can be accessed through the DBMS, simplifying the complexity for users and application programs.
Advantages of Database Management System (DBMS)
-
Improved Data Sharing:
- Enables end users to access better-managed data, allowing for quicker responses to environmental changes.
-
Improved Data Security:
- Enhances data security through enforced policies, reducing risks of breaches due to increased data access.
-
Better Data Integration:
- Promotes an integrated organizational view, making it easier to assess the impact of actions across different segments.
-
Minimized Data Inconsistency:
- Reduces discrepancies in data representation (e.g., variations in names or prices), thus leading to more accurate data storage.
-
Improved Data Access:
- Facilitates rapid responses to ad hoc queries, allowing users to perform data manipulation efficiently.
