What data modeling is, essentially, is a way to visualize metadata, which lies at the heart of enterprise data management and governance, and better understand complex datasets. A data model can help break down the complexity of diverse data sources and help users find and make connections in their data—a must when using big data for analytics.

It rules out any chances of data redundancy and omission. This helps in clear analysis and processing. Data modeling improves data quality and enables the concerned stakeholders to make data-driven decisions. For those unfamiliar with the term, what data modeling is, essentially, is a formal representation of the content and structure of data and determines how data is stored and accessed. It shows the logical inter-relationships and data flow between different data elements, helping users map their data landscapes.

They usually start with Top-down logical data models, Those workflows generally look like this: Identify the entities. The process of data modeling begins with the identification of the things, events or concepts Identify key properties of each entity. Each entity type can be differentiated from all others because it has one or Identify Data Modeling refers to the practice of documenting software and business system design.
