Main differences and Application scenarios between MyISAM and InnoDB

Main differences:

1) .MyISAM is non-transaction-safe, while InnoDB is transaction-safe. The granularity of MyISAM locks is table-level, while InnoDB supports row-level locking 3) .MyISAM supports full-text indexing while InnoDB does not support full-text indexing. 4) .MyISAM is relatively simple, so it is better than InnoDB in efficiency, and small applications can consider using MyISAM. 5). The MyISAM table is saved as a file, so using MyISAM storage in cross-platform data transfer will save a lot of trouble. 6). InnoDB tables are more secure than MyISAM tables and can switch from non-transactional tables to transactional tables (alter table tablename type=innodb) without losing data.

Application scenarios:

1) .MyISAM manages non-transactional tables. It provides high-speed storage and retrieval, as well as full-text search capabilities. If you need to execute a large number of SELECT queries in your application, then MyISAM is a better choice. 2) InnoDB is used in transaction processing applications and has many features, including ACID transaction support. If you need to perform a large number of INSERT or UPDATE operations in your application, you should use InnoDB, which can improve the performance of multi-user concurrent operations.
