Transactions isolation levels 1 question Know the terms 'dirty read', 'non-repeatable read', 'phantom read' and so forth. Recognize isolation levels of transactions. Identify levels of isolation provided by the Spring Transaction API.	5	49	2	Add a question Beta questions
Transaction Managers 2 questions Recognize various kinds of the transaction managers. Demonstrate how to wire them with their dependencies in the configuration file. Know that JtaTransactionManager allows to use distributed transactions.	6	32	4	Add a question Beta questions
Programmatic transactions 2 questions Demonstrate how to use TransactionTemplate together with the transaction callback. Show how to wire transaction manager to TransactionTemplate. Provide examples of how to use transaction manager directly in the code. Recognize various callback interfaces. Explain the purpose and direct usage of the TransactionStatus class.	4	22	2	Add a question Beta questions
Declarative transactions 2 questions Understand that Spring uses AOP in order to provide declarative transactions. Provide examples of the proper wiring configuration of the TransactionProxyFactoryBean. Use autoproxying features of the Spring AOP API in order to remove boilerplate configuration code. Demonstrate how to make all or only some of the methods of the bean transaction-aware. Identify how to configure Spring declarative transactions using annotations and xsd configuration.	8	27	4	Add a question Beta questions
Configuring transactions 2 questions Recognize and describe four main attributes of each Spring transaction: Propagation Isolation Read-only setting Timeout Show how to create transaction with the default attributes' values. Configure each attribute of the declarative transactions using various techniques (by direct configuration of the TransactionProxyFactoryBean in the wiring file, via implementations of TransactionAttributeSource, annotations and so forth). Configure transactions directly using programmatic transactions. Know that Spring rollbacks unchecked exceptions by default - describe how to change that behavior.	7	51	1	Add a question Beta questions
