What does TPs mean?

Tps (transaction processing system) usually refers to transaction processing system.

Also known as Electronic Data Processing System (EDPS), it refers to the lowest management system of an enterprise, which is used to process the transaction information generated in the daily operation of the enterprise.

The original form of TPS has a small design scope, such as reservation system and accounting cost accounting system. Its characteristics are highly structured when dealing with problems, but its functions are single, such as inventory material statistics system and employee salary distribution system.

The information it provides is the real-time information of the enterprise and the direct reflection of the enterprise situation. The operation of TPS directly simplifies people's daily work and improves the work efficiency of managers at the operation level. Under certain circumstances, it can even completely replace the manual operation of the operation layer.

TPS exists in all functional departments of an enterprise. It is a basic business system for daily business processing, recording, summarizing, synthesizing and classifying, serving the business level of the organization. Therefore, it is the link between enterprises and customers and the foundation of other information systems.

Acidic properties of TPS:

When the transaction processing system creates a transaction, it will ensure that the transaction has certain characteristics. Component developers assume that the characteristics of transactions should be characteristics that they do not need to manage themselves. These characteristics are called acidic characteristics.

Acids are atomicity, consistency, isolation and persistence.

1 atomicity

Atomicity attributes are used to identify whether a transaction is completely completed. Any update of the transaction should be completely completed on the system. If an error occurs for some reason and the transaction cannot complete all its tasks, the system will return to the state before the transaction starts.

2. Consistency

Transactions achieve the consistency of system integrity, which is achieved by ensuring that any transaction in the system is finally in a valid state. If the transaction is successfully completed, all changes in the system will be applied correctly and the system will be in a valid state.

If there is an error in the transaction, all changes in the system will be automatically rolled back and the system will be restored to its original state. Because the system was in a consistent state at the beginning of the transaction, the system is still in a consistent state.

Step 3 isolate

Transactions are executed in isolation as if they were the only operations performed by the system at a given time. If two transactions run at the same time and perform the same function, transaction isolation will ensure that each transaction thinks that only the transaction is using the system in the system.

Step 4 stick to it

Persistence means that once the transaction is successfully executed, all changes in the system will be permanent. There should be some checkpoints to prevent information loss in case of system failure.

Even if the hardware itself fails, the state of the system can still be rebuilt by recording the tasks completed by the transaction in the log. The concept of persistence allows developers to think that completed transactions are a permanent part of the system no matter what happens in the future.

All these transaction characteristics, no matter how related they are internally, only ensure that the data involved in the transaction can be managed correctly from the beginning to the completion of the transaction, regardless of whether the transaction is successful or not.

Generally, there are three processing methods in a transaction processing system: batch processing method, online processing method and online input delay processing method.
