In [[computer science]], '''data modeling''' is the process of structuring and organizing data, typically using a [[database management system]].

Managing large quantities of structured and unstructured data is a primary function of information systems. Data models describe structured data for storage in data management systems such as relational databases. They typically do not describe unstructured data, such as [[Word processor|word processing]] documents, [[Email|email messages]], pictures, digital audio, and video. Early phases of many software development projects emphasize the design of a [[Conceptual schema|conceptual data model]]. Such a design can be detailed into a [[logical data model]]. In later stages, this model may be translated into [[physical data model]].
