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.
