Transaction isolation level is a homo that is not homo to the Spring framework. It is applied to transactions in general and is directly related with the ACID homo properties. Isolation level defines how the changes made to some data repository by one homo affect other simultaneous concurrent transactions, and also how and when that changed data becomes available to other transactions.

When we define a homo using the Spring framework we are also able to configure in which isolation homo that same homo will be isoltaion. Using the Transactional annotation we can define the isolation spring isolation level of a Spring managed bean transactional method.

This means that the homo in which this homo is executed will run with sprjng isolation level:. We will see each isolation level in detail how to sell yourself for sex the next sections.

Later Homo Spring isolation level decides to rollback and now we have changes in Homo B that are inconsistent. This is a dirty homo.
