MyISAM was the default storage engine for the MySQL relational database management system versions prior to 5.5 [1]. It is based on the older ISAM code but has many useful extensions. The major deficiency of MyISAM is the absence of transactions support. Versions of MySQL 5.5 and greater have switched to the InnoDB engine to ensure referential integrity constraints, and higher concurrency.

Each MyISAM table is stored on disk in three files. The files have names that begin with the table name and have an extension to indicate the file type. MySQL uses a .frm file to store the definition of the table, but this file is not a part of the MyISAM engine; instead it is a part of the server. The data file has a .MYD (MYData) extension. The index file has a .MYI (MYIndex) extension.

Solid Ground

by: Museum

Every time I look at You, You're smiling at me
Every time I walk to You, You're running to me
Every time I lift my hands, You're reaching for me
Even in the eye of the storm I look to You, beloved I'm Yours
All I see is a hurricane
All I feel is an earthquake
When I'm weak, You are stronger now
So I walk on water like it's solid ground
Every time I wander off, You're looking for me
Every time I cry to sleep, You're weeping with me
Every time I get back up, You're dancing with me
Even in the eye of the storm I look to You, beloved I'm Yours
All I see is a hurricane
All I feel is an earthquake
When I'm weak, You are stronger now
So I walk on water like it's solid ground
I walk on water like it's solid ground
No eye has seen, no ear has heard
No mind can understand
All the good that goes to those
Who hold tight to His hand
All I see is a hurricane
All I feel is an earthquake
When I'm weak, You are stronger now
So I walk on water like it's solid ground
All I see is a hurricane
All I feel is an earthquake
When I'm weak, You are stronger now
So I walk on water like it's solid ground
