DBMS/U1 Topic 2 Data versus Information
Data is a raw and unorganized fact that required to be processed to make it meaningful. Data can be simple at the same time unorganized unless it is organized. Generally, data comprises facts, observations, perceptions numbers, characters, symbols, image, etc.
Data is always interpreted, by a human or machine, to derive meaning. So, data is meaningless. Data contains numbers, statements, and characters in a raw form.
Information is a set of data which is processed in a meaningful way according to the given requirement. Information is processed, structured, or presented in a given context to make it meaningful and useful.
It is processed data which includes data that possess context, relevance, and purpose. It also involves manipulation of raw data.
Information assigns meaning and improves the reliability of the data. It helps to ensure undesirability and reduces uncertainty. So, when the data is transformed into information, it never has any useless details.

|Dependence||It never depends on Information||It depended on Data.|
|Measuring unit||Measured in bits and bytes.||Measured in meaningful units like time, quantity, etc.|

|Knowledge level||It is low-level knowledge.||It is the second level of knowledge.|
