OLTP stands for what in database design?

OLTP stands for Online Transaction Processing, which is a key concept in database design. This term refers to a class of software applications that facilitate and manage transaction-oriented applications, typically for data entry and retrieval processes. OLTP systems are characterized by their ability to handle numerous requests simultaneously and ensure the accuracy and integrity of data through a range of transaction processing functions.

These systems are essential in environments that require real-time data processing, such as banking, order entry, and retail. They are designed to support a large number of transactions by multiple users concurrently, making them efficient for operational tasks that involve quick response times and consistency in data management.

In contrast, the other options represent terms or concepts that either do not exist as standardized terminology in database management or do not accurately describe the function of OLTP systems. Online Transaction Planning and Operational Layer Transaction do not align with established industry terminology, while Operational Transaction Protocol is not commonly recognized in the context of database design principles. Therefore, the choice of Online Transaction Processing is the most accurate and widely understood definition within the realm of database design.
