Captions available
The idea
A transaction is a single logical unit of work that accesses and possibly modifies a database through read and write operations — several commands, one unit.
In practice
A student registering for three courses is one transaction wearing three commands.
Where people slip
The unit boundary is a design decision with consequences.
