海外TECH	DEV Community	Transactions in .NET: From Basics to Best Practices	https://dev.to/bytehide/transactions-in-net-from-basics-to-best-practices-130o	Transactions in NET From Basics to Best Practices What is a Transaction in NET A transaction is a sequence of operations performed as a single logical unit of work Transactions are used to ensure the consistency and integrity of data in database systems They follow the ACID properties Atomicity Consistency Isolation and Durability In the context of NET transactions can be managed through various classes and interfaces provided by the NET Framework Importance of Transactions in Database ManagementTransactions are crucial for maintaining data integrity and consistency in database systems They ensure that multiple operations occur atomically either all succeeding or all failing preventing partial updates that could leave the database in an inconsistent state Transactions also help to isolate concurrent operations ensuring that each transaction s changes are isolated from others until they re committed Types of Transactions in NET Local TransactionsLocal transactions are transactions that involve a single resource such as a single database or a single message queue They are simpler and faster compared to distributed transactions as they involve only one resource manager In NET local transactions can be implemented using the TransactionScope class or the SqlTransaction class Distributed TransactionsDistributed transactions involve multiple resources such as multiple databases or a combination of databases and message queues They are more complex and slower than local transactions as they require coordination between multiple resource managers In NET distributed transactions can be implemented using the TransactionScope class in conjunction with the System Transactions namespace Working with Transactions in NET TransactionScope Class Creating a TransactionScopeThe TransactionScope class available in the System Transactions namespace allows you to define a block of code that participates in a transaction To create a new transaction scope you simply create a new instance of the TransactionScope class like so using TransactionScope scope new TransactionScope Perform transactional operations here Committing and Rolling Back TransactionsBy default a transaction will be committed when the TransactionScope is disposed To commit the transaction you can call the Complete method using TransactionScope scope new TransactionScope Perform transactional operations here scope Complete If an exception occurs within the TransactionScope the transaction will be rolled back automatically using TransactionScope scope new TransactionScope try Perform transactional operations here scope Complete catch Exception ex Handle the exception and let the transaction roll back SqlTransaction Class Establishing a ConnectionThe SqlTransaction class available in the System Data SqlClient namespace allows you to manage transactions directly on a SQL Server database To use SqlTransaction you first need to establish a connection to the database using the SqlConnection class using SqlConnection connection new SqlConnection connectionString connection Open Perform transactional operations here Implementing SqlTransactionOnce you have an open connection you can create a new instance of the SqlTransaction class by calling the BeginTransaction method on the SqlConnection objectusing SqlConnection connection new SqlConnection connectionString connection Open using SqlTransaction transaction connection BeginTransaction try Perform transactional operations here transaction Commit catch Exception ex Handle the exception and roll back the transaction transaction Rollback Isolation Levels in NET Transactions Read UncommittedThis isolation level allows transactions to read uncommitted changes made by other transactions It is the lowest level of isolation and can lead to issues such as dirty reads non repeatable reads and phantom reads Read CommittedEnsures that a transaction can only read committed changes made by other transactions It prevents dirty reads but can still result in non repeatable reads and phantom reads Repeatable ReadRepeatable read level prevents dirty reads and non repeatable reads by locking the data being read by a transaction However it can still result in phantom reads SerializableThis is the highest level of isolation which prevents dirty reads non repeatable reads and phantom reads by locking the entire range of data being accessed by a transaction This level of isolation can lead to reduced concurrency and potential deadlocks SnapshotThis isolation level provides a snapshot of the data at the start of a transaction allowing for consistent reads without acquiring locks It prevents dirty reads non repeatable reads and phantom reads while still allowing for high concurrency Best Practices for Implementing Transactions in NET Choose the appropriate transaction type Use local transactions when working with a single resource and distributed transactions for multiple resources Use the correct isolation level Select the isolation level that provides the necessary consistency guarantees without sacrificing performance Keep transactions short Minimize the duration of transactions to reduce the potential for contention and deadlocks Handle exceptions properly Ensure that transactions are rolled back in the case of an error or exception Close connections and dispose of resources Always close database connections and dispose of transaction objects to prevent resource leaks ConclusionTransactions are an essential part of maintaining data integrity and consistency in database systems In NET you can work with transactions using classes such as TransactionScope and SqlTransaction By understanding the different types of transactions isolation levels and best practices you can implement robust and efficient transactions in your NET applications	2023-05-01 09:44:05
