Study Notes

Primary Function of DBMS

A Database Management System (DBMS) primarily facilitates the creation, retrieval, updating, and management of data in databases.
It acts as an intermediary between users and the database, allowing for efficient data handling and organization.

Common Types of DBMS

Relational DBMS (RDBMS) is the most common type, utilizing tables to store data and relationships between them.
Other types include Hierarchical DBMS, Network DBMS, and Object-oriented DBMS, each with different data structure approaches.

Benefits of Using a DBMS

One important benefit of using a DBMS is improved data integrity and security, allowing for control over who can access and manipulate data.
DBMS also enhances data sharing, avoids data redundancy, and improves consistency across multiple applications.

Unsupported Operations by DBMS

Direct manipulation of the operating system files is typically not supported by a DBMS, prioritizing data access through its own interface and protocols.

Data Integrity Features

DBMS ensures data integrity through constraints, such as primary keys and foreign keys, which maintain accurate and consistent relationships within the data.
Transaction management features, including ACID properties (Atomicity, Consistency, Isolation, Durability), also bolster data integrity in DBMS operations.
