This is because software follows the rule of “Garbage in – garbage out.” Utmost care should be taken to provide the right data. If the input is not done properly or done wrong, then the result will be adversely affected. Input: This is the feeding of raw and sieved data for processing.This is a broad step in reducing the quantity of data to yield a better result. This stage required you to remove the extra or unusable data to make processing faster and better. Preparation includes sorting and filtering of data which will finally be used as input. Preparation/ Sieving: Some people consider this as a part of processing but does not involve any processing.Depending upon the data requirement its source must be identified from which data will be collected. This data might include census data, GDP or other monetary figures, data about a number of industries, profit of a company, etc. This data collection can be done in various ways by primary or secondary sources. The quality of input will determine the quality of output. Collecting data is a hard work in its own but is most essential on which the results depend. Data Collection: This is the first step which will provide the data for the input.Related: Data Mining, What is Data Mapping, Importance of data processing These deal with the collection of data, choosing the processing methods, practicing data management best practices, information processing cycle, making use of processed data for the desired purpose. These are the steps/ process required in between these three broad stages. Stages of the Data Processing CycleĪs discussed earlier data processing have three broad stages which have sub stages or steps involved. Output – This is the outcome and the raw data provided in the first stage is now “processed” and the data is useful and provides information and no longer called data.
This is the most important step as it provides the processed data in the form of output which will be used further. Processing – Once the input is provided the raw data is processed by a suitable or selected processing method.This is considered the first step and called input. Input – The raw data after collection needs to be fed in the cycle for processing.
