A data model is a collection of conceptual tools for describing the It merges the object- oriented data model with the dominant record-based model, the relational model. The effective teaching of data modelling concepts is very important; it constitutes the fundament of database planning methods and the handling of databases with the help of database management languages, typically SQL. Major. Data Modelling Concepts in Data Science. Data modeling is a process used to define and analyze data requirements needed to support the business processes within the scope of corresponding information systems in organizations.
