1. Identifying the data
Accuracy of information depends on accurate data input. The first step in data processing therefore, is to locate necessary facts and figures from source documents. Accurate, relevant and adequate data must be used as input.
2. Input of data:
After extracting the necessary data from the source documents, they must be transposed in a suitable form acceptable to the computer. Great care should be taken to avoid wrong entries in the forms.
3. Manipulation of data:
It involves the process of shifting, sorting and rearranging the given input. Before processing, validation procedures may be built in to the code to so that input forms do not accept any incorrect data.
4. Output of information:
The main purpose of data processing is to provide meaningful information to the decision-maker. Hence, in data processing the person involved must be very careful about what information is needed and in what form he likes to have it.
5. Storage of information:
The data processed need to be kept for future use. All the processed data will need some form of secondary storage. When storing the data, it is always important to maintain a backup. It should be noted that at each and every step the storage might be done.
