MySQL storage engine sorting and MySQL storage engine sorting01.MyISAMDefault storage engine before MySQL 5.0. MyISAM does not support transactions or foreign keys. Its advantage is that the access speed is fast, you can use this engine to create tables for applications that do not require transaction integrity or that use SELECT or INSERT statements. Each MyISAM is stored as three files on the disk. The file names are the same as the table names, but the extensions are :.
