The data after some processing needs to be transformed into useful information that can be used to make better decisions.
Some of the operations performed on data to get this output include the following:
1. Data generation: This involves the operations of collecting original raw data. This raw data is collected and set out in the form of original document called a source document.
2. Recording: Here, the raw data is converted into an acceptable form.
3. Verification: After the data has been recorded, their accuracy has to be checked.
4. Classification: This is the stage where the recorded data is grouped into categories for easy retrieval.
5. Sorting: This involves sequencing the data in a pre-determined order to facilitate data processing.
6. Merging: This is the operation of combining two or more ordered sets of data to form another single ordered set.
7. Calculating: This involves the manipulation of data. Calculation would usually involve solving equations and manipulation of the source data such as addition, subtraction, multiplication and division.
8. Data Storage: The result of data processing is stored for reference. The basic requirement for utilizing the computer in all business applications is the ability to store and access data. The data is stored in a location called memory referred to by its address.
