In a three-tier design, **OLTP** is an **[operating system](https://answers.mindstick.com/qa/92621/which-operating-system-will-be-best-for-the-mobile)** that supports **transaction**-**oriented applications**. It is in charge of an organization's day-to-day operations. **OLTP** is primarily concerned with query processing, data integrity in multi-access scenarios, and effectiveness, which is assessed in terms of total transactions per second. **OLTP** stands for **Online Transaction Processing** in its full form. \
An **online** **database changing system** is known as an **OLTP system**. As a result, it allows database queries including **inserting**, **updating**, and **deleting data** from the **database**. \
The following are some of the most important properties of **OLTP**: \

- In **OLTP**, transactions containing little amounts of data are employed.
- The database's indexed data is easily accessible.
- There are a lot of people who use **OLTP**.
- Its response times are quick.
- End-users have direct access to databases.
- **OLTP** uses a fully normalized structure to ensure database consistency.
- The **OLTP** system is quick to respond.
- It strictly performs the predefined operations on a small number of records.
- The records from the previous several days or a week are stored in **OLTP**.
- It is capable of handling complex data models and tables.

The **ATM** **center** is an example of an **OLTP** system. Assume that a couple has a joint bank account. One day, they both arrive at different **ATM terminals** at the same time and want to withdraw the entire balance in their bank accounts.\

The individual who completes the authentication process first, on the other hand, will be allowed to receive money. In this situation, the **OLTP** system ensures that the amount withdrawn is never greater than the amount in the bank. The important thing to keep in mind is that **OLTP** systems are designed for **transactional supremacy** rather than data analysis.\
