   In MySQL, major difference of InnoDB and  MyISAM are given below. MyIsam is supporting the table level locking in database. But InnoDB is supporting the row level locking in the database. MyIsam is supporting the FULL TEXT SEARCH functionality and InnoDB also supporting the FULL TEXT SEARCH after MySQL Version of 5.6.4.

 

 MyISAM Engine : 

1. It supporting Table-level Locking
2. It supports FULLTEXT SEARCH functionality
3. It is designed for need of speed
4. It is not supporting foreign key constraints
5. It is storing the data as its tables, data and indexes in diskspace using separate three different files formats. (table.FRM, table.MYD, table.MYI)
6. It is not supporting transactions [ We can't COMMIT and ROLLBACK the comments ]
7. It recovering data by using Requires full repair/rebuild of indexes/tables
8. It is storing the data as no ordering format

INNODB Engine : 

1. It is supporting Row-level Locking
2. After MySQL Version 5.6.4 ,Supporting FULL TEXT SEARCH functionality
3. It is designed for maximum performance when processing high volume of data
4. It is supporting foreign key constraints
5. It is supporting transactions [ We can COMMIT and ROLLBACK the comments ]
6. It stores data as tables and indexes in a tablespace
7. It is Auto recovery from crash via replay of logs
8. It is stored the data row as primary key order
