The difference between Oracle database and MySQL
Relational model
- Oracle Database: Based on the relational data model, supports complex transactions and data integrity constraints.
- MySQL: Also based on the relational data model, but focused on speed and flexibility.
Compatibility
- Oracle Database: Provides a high degree of compatibility with the SQL standard, supporting OLTP and OLAP workloads.
- MySQL: Highly compatible with MariaDB, supporting NoSQL and JSON data types.
Scalability
- Oracle Database: Scalable to support large enterprise-level data sets, providing high availability, performance and reliability.
- MySQL: Suitable for small to medium-sized data sets, easily scalable to distributed environments.
Data Types
- Oracle Database: Provides a wide range of data types, including object-relational, spatial, and XML.
- MySQL: Focus on basic data types, but supports extended types for enhanced flexibility.
Query Performance
- Oracle Database: Optimized query optimizer and indexes to provide high query throughput.
- MySQL: Emphasis on fast query speed, especially in read-intensive workloads.
Security
