https://docs.microsoft.com/en-us/azure/architecture/data-guide/relational-data/online-transaction-processingThe quality assurance application described reads data from a data warehouse, which suggests that it is likely a reporting or analytics application. There are several types of processing that can be used to process data in different ways, each with its strengths and weaknesses.
A. Online Transaction Processing (OLTP): OLTP is a type of processing that is optimized for transactional workloads, such as updating a database record, inserting a new record, or deleting a record. OLTP systems are designed to handle many small, short-lived transactions quickly and efficiently, and ensure the integrity of the data in the process.
B. Batch Processing: Batch processing involves collecting and processing data in large batches, typically overnight or during periods of low system activity. Batch processing is often used for tasks that require a lot of processing power or that involve large volumes of data that would be impractical to process in real-time.
C. Online Analytical Processing (OLAP): OLAP is a type of processing that is optimized for analytical workloads, such as generating reports or analyzing data to gain insights. OLAP systems are designed to quickly retrieve and manipulate large volumes of data to support ad-hoc queries and data analysis.
D. Stream Processing: Stream processing involves processing data in real-time as it is generated, rather than waiting for it to be collected in batches. Stream processing is often used for applications that require immediate processing of data, such as real-time analytics or fraud detection.
Based on the description provided, the most likely type of processing that the quality assurance application uses is Online Analytical Processing (OLAP), as it is designed for reading data from a data warehouse to generate reports and perform analytics.
