Data processing simply means the process or way or method that describes how data is being converted/changed into information.

                                 DATA PROCESSING INFORMATION

This can be done by:

  1. Calculating
  2. Sorting
  3. Classifying
  4. Summarizing
  • Calculating:

This involves arithmetic manipulations such as addition, subtraction, etc. on numeric data.

  • Sorting:

This involves arranging data in a predetermined order or sequentially.

  • Classifying:

This involves putting items of data in a certain category based on their similarities, characteristics, e.g. age, sex, level of education, height, weight, nationality, eye colour etc.

  • Summarizing:

This involves condensing information in a manner that makes it easily identified for use by the user of such information.

Data processing stages

These are the stages involved in data processing. They include the following under listed stages:

 1. Data Gathering:

This is the stage where data to be processed is searched for until it is available e.g. a record of students’ attendance, the number of savings accounts holders, etc.

2. Data Collation:

This is the stage where data gathered is collated or brought together e.g. students’ attendance from various schools in a local government brought together for analysis.

3. Input Stage:

This is the stage where the data is fed into the machine or computer ready for processing.

4. Processing Stage:

This is the stage where the data is processed depending on the information that is required as output.

5. Storage Stage:

This is the stage where the result of processing data is stored in memory for short or long term uses.

6. Output Stage:

This is the stage where the result of the processing is displayed or brought out for the users to understand and make use of.
