MySQL enforces ACID properties through COMMIT, ROLLBACK & logging mechanism ensuring atomicity, consistency, isolation & durability of database transactions.

MariaDB & MySQL differ in storage engines, analytics, thread pooling & community governance. MariaDB offers extended support for engines like Aria & MyRocks, built-in analytics with ColumnStore & massive concurrency with thread pooling.

Analyze slow queries with EXPLAIN plan in PostgreSQL: identify inefficiencies & optimize query performance with actual execution statistics & costs.

MySQL shutdown unexpectedly? Check if port is blocked by software or firewall, verify config settings & ensure MySQL port is free. Cleaning InnoDB engine can help if other steps fail.

Essential SQL commands include SELECT, INSERT, UPDATE, DELETE, COMMIT, GRANT & DML/DDL/DCL/TCL categories for effective database management.

MySQL wildcards offer flexible searches with LIKE and FULLTEXT. Use % for multiple chars, _ for single char, * in BOOLEAN MODE for fulltext search. Ideal for incomplete strings and improving database querying.

Containerize MySQL with Docker: Write a Dockerfile, build & run image, connect to containerized DB using DbVisualizer for seamless deployment across environments.

PostgreSQL & MySQL share similarities like open-source, relational model, SQL support & robust user management. Key differences include advanced data types, auto-increment functionality, concurrency control & full-text search capabilities.

pg_dump creates PostgreSQL backups with features like SQL script backup, restore, directory-format archive & data-only export.

Converting data types with PostgreSQL's CAST function is key to efficient database management. Use CAST(value AS target_data_type) for seamless conversions.

ibdata1 stores metadata & transaction logs, crucial for MySQL's performance & reliability. Enable innodb_file_per_table & perform regular maintenance to prevent oversized issues.

Views fetch dynamic data, while materialized views store query results for faster access but less current data.
