Inutdata

Inutdata is a term used in data engineering to denote the raw input data that enters a data processing system before any cleaning, normalization, or transformation. It is contrasted with processed data, intermediate representations, and derived data within data pipelines, and is commonly referenced in pipeline diagrams and data dictionaries to emphasize data provenance.

Etymology and scope: The word is generally understood as a contraction of "input" and "data." While not universally standardized, it is used to label the unprocessed data that feeds computational workflows. In practice, inutdata can originate from diverse sources such as application logs, sensor streams, transactional exports, or external data feeds, and may be structured, semi-structured, or unstructured.

Characteristics and management: Inutdata often contains noise, duplicates, and missing values, and may include sensitive information. It is typically stored in its native or minimally transformed form, accompanied by metadata such as source, timestamp, and version. Formats commonly encountered include CSV, JSON, log files, and various binary streams. Organizations implement retention policies, access controls, and privacy measures for inutdata, along with data catalogs and lineage tracking to support auditing and reproducibility.

Role in workflows: The primary role of inutdata is to enable reproducible data processing and validation. By retaining the raw input, data engineers can verify preprocessing steps, diagnose quality issues, and reprocess data as schemas evolve or new requirements emerge.
