This overview covers the fundamentals of database replication, exploring both file-based and database-based methods. We delve into asynchronous and synchronous replication, discussing their mechanisms, including caching and data transfer techniques. The anatomy of a database is examined, from tables and indexes to transaction logs, ensuring data integrity and recovery processes. Additionally, we address the security issues associated with different replication approaches and highlight strategies for effective backup and restoration, emphasizing the importance of reliable data management.
