What data management method does Oracle belong to?
Oracle belongs to Relational Database Management System (RDBMS) .
Detailed explanation:
A relational database management system is a database management system that stores data in relational data structures called tables. Each table consists of rows and columns, with each row representing a record and each column representing a specific attribute of the record.
Oracle is one of the most commonly used relational database management systems, with the following characteristics:
- Relational data model: Data is stored in tables, between tables The relationship between is defined through foreign keys.
- SQL language: Access and manage data using Structured Query Language (SQL).
- Transaction processing: Supports transaction processing to ensure data consistency during operations.
- Data integrity: Provide data integrity constraints to prevent invalid or inconsistent data from entering the database.
- Concurrency control: Through locking and concurrency control mechanisms, multiple users are allowed to access the database at the same time.
- Data recovery: Provides data backup and recovery mechanism to prevent data loss or damage.
Other types of database management systems include:
- Distributed database management system: Data is stored in multiple physical locations.
- Object database management system: Data is stored as objects, with properties and methods.
- NoSQL database management system: does not use the relational data model and is more suitable for large-scale unstructured data.
