SQLite is a self-contained, serverless, zero-configuration SQL database engine that stores an entire database in a single file on disk. Unlike MySQL, PostgreSQL, and MongoDB which require a running server process, SQLite is a library that is linked directly into the application — there is no network connection, no authentication, and no administration overhead. SQLite […]

How to Back Up PostgreSQL with pg_dump and pg_basebackup on RHEL 9

PostgreSQL provides two complementary backup tools: pg_dump for logical backups of individual databases (SQL statements that can be restored to any PostgreSQL version) and pg_basebackup for physical backups of the entire database cluster (exact byte-for-byte copy of the data directory, used for streaming replication setup and point-in-time recovery). pg_dump is the right tool for most […]

How to Set Up PostgreSQL Streaming Replication on RHEL 9 — step-by-step RHEL 9 tutorial on Progressive Robot

How to Set Up PostgreSQL Streaming Replication on RHEL 9

PostgreSQL Streaming Replication sends WAL (Write-Ahead Log) records from a primary server to one or more standby servers in near-real-time, keeping standbys continuously synchronised with the primary. This provides high availability (automatic or manual failover when the primary fails), read scaling (queries can be distributed to hot standbys), and geographic redundancy. Unlike logical replication which […]

How to Install MongoDB 7 on RHEL 9 — step-by-step RHEL 9 tutorial on Progressive Robot

How to Install MongoDB 7 on RHEL 9

MongoDB is a document-oriented NoSQL database that stores data as BSON (Binary JSON) documents rather than rows in tables. This schema-flexible approach makes MongoDB ideal for applications with rapidly evolving data models, hierarchical data (product catalogs, user profiles, content management), geospatial queries, and high-volume write workloads. MongoDB 7.x introduced significant improvements including multi-document ACID transactions, […]
