What Is Data Processing: Types, Methods, Steps and Examples for Data Processing Cycle

Whether you use the internet to learn about a certain topic, complete financial transactions online, order food, etc. The use of social media, online shopping and video streaming services have all added to the increase in the amount of data.

A study by Domo estimates that 1. And in order to utilize and get insights from such a huge amount of data - data processing comes into play. And in this article, we will cover the following topics in detail:. Data in its raw form is not useful to any organization. Data processing is the method of collecting raw data and translating it into usable information.

It is usually performed in a step-by-step process by a team of data scientists and data engineers in an organization. The raw data is collected, filtered, sorted, processed, analyzed, stored and then presented in a readable format. Data processing is crucial for organizations to create better business strategies and increase their competitive edge.

By converting the data into a readable format like graphs, charts and documents, employees throughout the organization can understand and use the data.

The data processing cycle consists of a series of steps where raw data input is fed into a process CPU to produce actionable insights output. Each step is taken in a specific order, but the entire process is repeated in a cyclic manner. The first data processing cycle's output can be stored and fed as the input for the next cycle.

The collection of raw data is the first step of the data processing cycle. The type of raw data collected has a huge impact on the output produced. Hence, raw data should be gathered from defined and accurate sources so that the subsequent findings are valid and usable. Data preparation or data cleaning is the process of sorting and filtering the raw data to remove unnecessary and inaccurate data.

Raw data is checked for errors, duplication, miscalculations or missing data, and transformed into a suitable form for further analysis and processing.

This is done to ensure that only the highest quality data is fed into the processing unit. In this step, the raw data is converted into machine readable form and fed into the processing unit.

This can be in the form of data entry through a keyboard, scanner or any other input source. In this step, the raw data is subjected to various data processing methods using machine learning and artificial intelligence algorithms to generate a desirable output.

This step may vary slightly from process to process depending on the source of data being processed data lakes, online databases, connected devices, etc. The data is finally transmitted and displayed to the user in a readable form like graphs, tables, vector files, audio, video, documents, etc.

This output can be stored and further processed in the next data processing cycle. The last step of the data processing cycle is storage, where data and metadata is stored for further use. This allows for quick access and retrieval of information whenever needed, and also allows it to be used as input in the next data processing cycle directly. There are different types of data processing based on the source of data and the steps taken by the processing unit to generate an output. There is no one-size-fits-all method that can be used for processing raw data.

Data is automatically fed into the CPU as soon as it becomes available. Used for continuous processing of data. Data is broken down into frames and processed using two or more CPUs within a single computer system. Also known as parallel processing. In this data processing method, data is processed manually. The entire process of data collection, filtering, sorting, calculation and other logical operations are all done with human intervention without the use of any other electronic device or automation software.

It is a low-cost method and requires little to no tools, but produces high errors, high labor costs and lots of time. Data is processed mechanically through the use of devices and machines. These can include simple devices such as calculators, typewriters, printing press, etc. Simple data processing operations can be achieved with this method.

It has much lesser errors than manual data processing, but the increase of data has made this method more complex and difficult. Data is processed with modern technologies using data processing software and programs. A set of instructions is given to the software to process the data and yield output.

This method is the most expensive but provides the fastest processing speeds with the highest reliability and accuracy of output.

Data processing occurs in our daily lives whether we may be aware of it or not. Here are some real-life examples of data processing:. Data contains a lot of useful information for organizations, researchers, institutions and individual users. With the increase in the amount of data being generated every day, there is a need for more data scientists and data engineers to help understand these data.

What is Data Processing?

Data Processing: Made Simple, Second Edition presents discussions of a number of trends and developments in the world of commercial data processing. The book covers the rapid growth of micro- and mini-computers for both home and office use; word processing and the 'automated office'; the advent of distributed data processing; and the continued growth of database-oriented systems. The text also discusses modern digital computers; fundamental computer concepts; information and data processing requirements of commercial organizations; and the historical perspective of the computer industry. The computer hardware and software and the development and implementation of a computer system are considered. The book tackles careers in data processing; the tasks carried out by the data processing department; and the way in which the data processing department fits in with the rest of the organization.


Data processing consists of the following basic steps - input, processing, and output. These three steps constitute the data processing cycle. • Input − In this step.

Data processing , Manipulation of data by a computer. It includes the conversion of raw data to machine-readable form, flow of data through the CPU and memory to output devices, and formatting or transformation of output. Any use of computers to perform defined operations on data can be included under data processing. In the commercial world, data processing refers to the processing of data required to run organizations and businesses.

What is data processing?

Data processing is, generally, "the collection and manipulation of items of data to produce meaningful information. The term Data Processing DP has also been used to refer to a department within an organization responsible for the operation of data processing applications. The United States Census Bureau history illustrates the evolution of data processing from manual through electronic procedures. Although widespread use of the term data processing dates only from the nineteen-fifties, [3] data processing functions have been performed manually for millennia. For example, bookkeeping involves functions such as posting transactions and producing reports like the balance sheet and the cash flow statement. Completely manual methods were augmented by the application of mechanical or electronic calculators.

Without data processing, companies limit their access to the very data that can hone their competitive edge and deliver critical business insights. Data processing occurs when data is collected and translated into usable information. Usually performed by a data scientist or team of data scientists, it is important for data processing to be done correctly as not to negatively affect the end product, or data output. Data processing starts with data in its raw form and converts it into a more readable format graphs, documents, etc. Read Now. Collecting data is the first step in data processing.
