The conceptual data model describes the data structure, which the business requires. The intended audience for conceptual data models is the business side of an organization. Kinds of Data ModelsĬonceptual data model – This particular model is a high-level representation of a database design that explains how data interrelate and what kind of data should be stored in the database. Data modeling is an essential skill for data scientists, data analysts, and others associated with data analysis. Alternatively, models can be designed as part of reverse-engineering efforts that extract models from existing systems, as seen with NoSQL data. It allows stakeholders to distinguish flaws and implement corrections before programming code is written. Ideally, a data model can be thought of as a flowchart that explains the connections among pieces of data.

The design can be used to guarantee the effective use of data as a blueprint for the development of new software or for reengineering a legacy application. The process of designing a simplistic diagram of a complex software system is termed data modeling. A data model can often be regarded as a roadmap, an architect’s blueprint, or any formal diagram that promotes a deeper understanding of what is being devised. These business rules are then transcribed into data structures to devise a concrete database design. The process commences by accumulating information about business requirements from stakeholders and end-users. Data can be modeled at different levels of abstraction.
