Types of Data Processing

Data pre-processing includes different types, each serving different purposes and therefore catering to the specific needs of Machine Learning. Some of the common types of Data Processing are:

Batch Processing

This type of data processing involves processing large volumes of data in batches. We process data collected over a long period of time together as a batch.

Batch processing is typically useful for non-real-time or offline cases where the need for instant results is not important. The technique often employs tasks such as data cleaning, aggregation, reporting, and generating reports in batches.

Real-Time Processing

This type of immediate data processing focuses on data that arrives immediately and involves handling and analysing data in real-time. It enables organizations to receive instant results and is common in applications requiring prompt decision-making.

Accordingly, these decisions are made on incoming data such as fraud detection, stock market analysis or real-time monitoring systems.

Online Processing

This type of data processing involves managing transactional data in real time and focuses on handling individual transactions. It includes transactions like recording sales, processing customer orders, or updating inventory levels. The systems are designed to ensure data integrity, concurrency, and quick response times to enable interactive user transactions. 

In online analytical processing, operations typically consist of significant fractions of large databases. Therefore, today’s online analytical systems provide interactive performance and the secret to their success is precomputation.

Time-Sharing Processing

In this type of processing, the CPU of a large-scale digital computer helps interact with multiple users with the help of different programs simultaneously. With this type of processing, solving several discrete problems during the input/output process is possible because the CPU is faster than most peripheral equipment. 

This helps the CPU to address each problem sequence-wise. However, remote terminals think that access to and retrieval from a time-sharing system enables instant outcomes. This is because the solutions are immediately available when the problem is entirely centred.

Distributed Processing

Distributed processing makes it possible to analyse data across multiple interconnected systems or nodes. This type of data processing enables the division of data and processing tasks among numerous machines or clusters. 

Therefore, distributed processing helps improve scalability and fault tolerance. It is commonly used for Big Data Analytics, databases, and distributed computing frameworks like Hadoop and Spark.

Multi-Processing

Multi-processing is the type of data processing in which two or more processors tend to work on the same dataset simultaneously. In this process, multiple processors are housed within the same system. 

Consequently, data is broken down into frames, and each frame is processed by two or more CPUs working in parallel in a single computer system.
