Table type Description Files used
BDB A transaction-safe table that the Berkeley DB handler .frm, .MYD, .MYI
manages. For the most part, InnoDB tables have replaced
BDB tables.
MEMORY A table whose contents are stored in memory. .frm
InnoDB A transaction-safe table that the InnoDB handler manages. .frm
As a result, data is not stored in a .MYD file, but instead is
managed in the InnoDB tablespace.
ISAM A deprecated table type that was once the default table .frm, .MYD, .MYI
type in MySQL. The MyISAM table type has replaced it,
although it is still supported for backward compatibility.
MERGE Avirtual table that is made up of multiple MyISAM tables. .frm, .MRG
Data is not stored in the MERGE table, but rather in the
underlying MyISAM tables.
MyISAM The default table type in MySQL. MyISAM tables, which .frm, .MYD, .MYI
have replaced ISAM tables, support extensive indexing
and are optimized for compressions and speed.
