It wasn’t too long ago that the term referred to an individual who was tasked with completing transactions, usually financial ones. This term is one of the many personification-based terms in modern IT. Transaction Managers Another basic element of transaction process systems is the transaction manager. (For some background reading on ACID, check out our Introduction to Databases.) In both cases, the goal is the same: total data resolution. The first example refers to ACID, while the second represents BASE. The other keeps going, winding down over time from a few tapering plunks and thunks all the way to eventual silence. One of them clacks furiously for a few seconds, then quits. For a simple idea of the way these two methods work, imagine two of those old analog marquee systems in a train station, where updates involve various shuffling pieces with timetable information.
Both of these models can guide IT professionals toward more consistent transaction processing systems. This "hard" system of verifying transactions led to another model called basically available, soft state, eventual consistency, or BASE, a more versatile alternative. One of these is called atomicity, consistency, isolation and durability, or ACID. So how does transaction processing help ensure this sort of durability? Let's take a look.ĪCID and BASE Transaction Models Over time, data specialists have produced various models that promote successful and durable transactions.
A TRANSACTION PROCESSING SYSTEM PRO
The opposite of a dropped transaction is what's called a "durable transaction." These durable transactions are the fundamental basis for many online activities, such as ticket or event booking, credit card processing, and other quid pro quo arrangements were multiple systems need to be updated, and one digital event has to align with another. Otherwise the system may have what is called a "dropped transaction," (or what Microsoft calls "losing integrity").
A TRANSACTION PROCESSING SYSTEM SOFTWARE
With other kinds of non-financial transactions, different parts of a software architecture need to be updated. The money has to come out of one account and go into another account.
In order to be successful, the process has to be completed from start to finish. When we talk about transaction processing, the term "transaction" refers to the entire process. Both can both be applied to standard e-commerce systems that handle financial transactions.
Experts contrast transaction processing with a different type of model called batch processing, where a larger number of individual transactions are handled collectively. That's partly because at its core, transaction processing is not just a term for financial transactions, although many TPS systems, such as those for credit card processing, may revolve around the process of money changing hands.Įssentially, transaction processing is a model for various transactions, including both financial transactions and other processes like verifications. However, like some of the other terms around IT, this label can seem a bit vague. Businesses of many different types may invest in a transaction process system as part of IT merchant services or other parts of the software architecture.
