These 3rd Party Vendors offering Magic Software Migration services forget that you are going to need to write your own code in C#.NET, ASP.NET or Java to make up for the transaction capabilities of the Magic xpa Application Platform.
Business applications frequently require transactional programming techniques. How easily one can program a transaction depends on the language and platform. The Magic xpa Application Platform enhances the .NET platform making it possible for Magic programmers to create transactions with significantly less effort than C#, ASP.NET or Java developers.
Transactions are an integral part of developing data-bound applications. A key to developing applications in a database environment is the ability to optimally use transactions to ensure data integrity.
The word “transaction” is used very often when discussing SQL applications. A transaction is an integral part of a process, contributing to the composition of the whole application, and it can be defined as the execution of a set of logically related data modifications, which must be committed (completed and written to disk) or aborted as a single unit.
This means that either the entire process succeeded or the entire process failed. There is no middle ground. Several operations such as UPDATE, DELETE and INSERT may create a single unit. Only if all the operations are successful, will this logical unit be successful.
A transaction process may be an entire business logic process or a smaller unit that is part of a business logic process.
Transactions can be used to secure Read operations, as opposed to Read/Write operations. A Read transaction ensures that the data read within the transaction is not modified by other users.
The transaction processing technique automatically logs all of the updates of a transaction to a temporary transaction file. The updates in this file are cleared only when the transaction is complete, that is, the updates to all the regular database tables have been completed successfully. If a problem is detected in any of the tables affected by the transaction, the entire transaction is canceled and the database is rolled back, that is, restored to its original state before the transaction occurred. The rollback uses the information stored in the Transaction Log file to restore the project.
Migrate Magic eDeveloper and uniPaaS to .NET by UpgradingThere are many challenging issues when implementing transactions using C# or ASP.NET. The first problem is isolation. The volatile resource must adhere to the isolation property of ACID, lock the underlying resource it manages, and prevent access by multiple transactions. However, C#.NET and ASP.NET only offer thread-based locks, which prevents access only by concurrent threads, not concurrent transactions. The second problem is state management. The resource manager needs to enable the transaction to modify the state of the resource and yet must be able to roll back any such changes if the transaction is aborted.
Magic xpa offers extensive transaction-handling capabilities that avoid heavy manual programming efforts in C# and Java. For additional information on how an upgrade is superior to 3rd Party Magic Software Migration conversion please convert here.
