advantages of transaction processing system

Otherwise, the users will not be able to change, or he has to wait for other users to complete so that there is not a deadlock situation.Ģ. Concurrency: OLTP ensures transactions made into the database should not deplete the concurrency between different users. Database tuning: An OLTP system can maximize its performance as efficiently and rapidly as possible using database tuning.ġ.Partition (database): It is used to increase performance for parts that have transactions on a regular basis and still maintains availability and security.It is similar to an operating system to maintain multithreaded operations. Transaction processing: It is used to coordinate different transactions over multiple computing devices.Dynamic allocation: It refers to the space allocated to tables and rollback segments.Buffer cache size: It is used to avoid unnecessary resource utilization by SQL statements.Blocksize: The size of the block should be multiple of the Operating system size to avoid non-required I/O operations.These are crucial in the case of short and non-distributed transactions. Discrete transactions: The transactions that revert all the changes made into the database until the last commit refers to discrete transactions.These clustering operations help in optimizing join operations. Clusters: It is a schema that has records of the columns that are common among different tables, which will further help in clustering.It also records the transactions rolled back and helps in the recovery of databases to avoid loss. This ensures consistency in the database among several users. Rollback segments: Rollback segments are the parts of the database that record the transactions that are rolled back.Some crucial segments that affect the performance of OLTP are OLTP is also carried into the service-oriented architecture (SOA) and Web services.For various decentralized database systems, OLTP brokering programs distribute transactions processes among multiple computers on a network.Online transaction processing (OLTP) involves gathering information as input, processing the data according to needs, and updating data to reflect the processing information.We can design such systems that help in performing operations whose database queries are usually simple, require less than second response times, and return comparatively fewer records.A large number of users can conduct short transactions using OLTP systems.Its goal is availability, speed, concurrency, and recoverability.As it only performs the task related to insertion/deletion, it maintains the consistency and concurrency of the data in the databases, which always ensures the availability of the databases.OLTP stores less historical data, which makes it efficient. OLTP works only on normalized databases with a small number of records at a time in a decentralized system that optimizes all the transactional tasks being predefined to the system.That is, if any steps between the transaction fail, all other steps must fail also. This is coined as Concurrency controls.Ītomicity controls guarantee that in a transaction, all steps are completed successfully as a group. In general, one user will process, and one will wait while making any amendments.

When two users trying to access the same data in a particular database system, none of them will be able to change the data until and unless one user has finished processing.

Online transaction process concerns concurrency and atomicity.

Maintaining historical data- It stores the records of the last few days or a week to successfully perform the transactions.

For example – ‘Retrieving the money from ATM.’

A small number of records – It processes only a handful of records only.

Updation of databases is directly accessible to end-users.

Predefined operations – It strictly performs only the predefined operations only on a small number of records.

3NF databases – It uses fully normalized databases to ensure the consistency and optimization of all the transactional tasks.
