NoSQL data modeling

Data modeling is the process of visually creating a graphical representation of a system or database. In the case of relational databases, we can mention the creation of entity-relational diagrams in which entities, attributes and relationships between entities are displayed. (Read more information about ER diagrams).

Advantages of data modeling

  • Fewer design and development errors
  • Easy and fast design, especially in the early stages of development
  • Better communication between team members
  • Time saving
  • Lower development costs
  • and many others
