Raw data (sometimes colloquially called "sources" data or "eggy" data, the latter a reference to the data being "uncooked", that is, "unprocessed", like a raw egg) are the data input to processing. A distinction is made between data and information , to the effect that information is the end product of data processing.
Data wrangling typically follows a set of general steps which begin with extracting the data in a raw form from the data source, "munging" the raw data (e.g. sorting) or parsing the data into predefined data structures, and finally depositing the resulting content into a data sink for storage and future use.

Free and open-source software portal; LibRaw is a free and open-source software library for reading raw files from digital cameras. It supports virtually all raw formats. It is based on the source code of dcraw, with modifications, [4] and "is intended for embedding in raw converters, data analyzers, and other programs using raw files as the initial data."
This is often followed by manual drill-down or filtering of the data to identify anomalies or patterns identified through the automated actions. Data exploration can also require manual scripting and queries into the data (e.g. using languages such as SQL or R) or using spreadsheets or similar tools to view the raw data. [4]
Raw intelligence is raw data gathered by an intelligence operation, such as espionage or signal interception. Such data commonly requires processing and analysis to make it useful and reliable. To turn the raw intelligence into a finished form, the steps required may include decryption, translation, collation, evaluation and confirmation. [2 ...
Applications like a database management system can use raw devices directly, enabling them to manage how data is cached, rather than deferring this task to the operating system. In FreeBSD, all device files are in fact raw devices. Support for non-raw devices was removed in FreeBSD 4.0 in order to simplify buffer management and increase ...
The HDRi raw data format is able to store the infrared raw data, which can be used for infrared cleaning, as an additional 16-bit channel. The remainder of the discussion about raw files applies to them as well. Some scanners do not allow the host system access to the raw data at all, as a speed compromise.
Data reporting is different from data analysis which transforms data and information into insights. Data reporting is the previous step that translates raw data into information. [1] When data is not reported, the problem is known as underreporting; the opposite problem leads to false positives. Data reporting can be difficult.
