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.
