Computer data processing is a process that uses a computer program to enter data and summerize, analyze, or convert data into usable information. The process of converting raw data into "information" is processing. Data processing can take on any of the following processes such as: data summarization, data aggregation, data validation, data tabulation, and statistical analysis.

Data Processing includes data analysis as well as the use of complicated algorithms that could be used to be able to draw conclusions from data. Merely looking at a large list of data can not tell a business person what business moves to make. However, when data is segmented, and certain elements are analyzed. A hotel might process data by looking to see how many percent of their guests leave early in the morning. That data could be used to determine when their continental breakfast would ideally begin.

Data summarization summarizes evaluational data in initial data as well as derived data. For business use, data summarization would be used to see the relationship between what a customer purchases, and how long they would remain a customer on average. Perhaps, someone who starts off with a big purchase, or asks a lot of questions is more likely to become a long term customer, while someone who only purchases a small item might be more likely to be a one time only customer. Statistitians could identify average salaries for people in various age groups and educational levels using data summarization.

Data aggregation is any process where information is gathered and summarized which is almost an identical concept as data summarization.

Data tabulation compiles data derived from a survey and presents it in the form of a statistic such as a national statistic that might be used by the government or sociologists. Data tabulation is very similar to data aggregation and data summarization, except it has a more formal and official tone to its use and meaning.

The process of turning facts into information involves processing. Data processing can involve: (1) Data summarization (2) Data aggregation (3) Data validation (4) Data tabulation (5) Statistical analysis. Data processing involves coding into a format recognizable by a program. Any process that uses a computer to enter data.
