• Organizing and analyzing data is no easy process. Modern businesses have more data than most realize. It's more important than ever to create a simplified way of viewing and interpreting it. That's where data modeling comes in. If you need data modeling software, visit this website.
  
  

  There are a few different types of data models available. Here are the most common.
  
  

  Hierarchical
  
  

  This model is pretty simple. The easiest way to look at it is to think of it as a tree. With a hierarchical model, you have a single root. Branching data then connects to that root, creating a tree-like structure.
  
  

  The goal is to explain the one-to-many relationship between different kinds of data. You can connect the dots, understand relationships, and see the bigger picture. For example, a company could be the "root" node. Meanwhile, the various departments making up the company would be the branches.
  
  

  Relational
  
  

  A relational data model is a bit different. It's about showing how each piece of data is similar and makes it easy to identify the relationship between data. Typically, this form of modeling utilizes interrelated tables. You group datasets and use the various rows and columns to view unique attributes in an entity.
  
  

  Network
  
  

  Network models are distinct because the data appears in the form of a graph. While hierarchal uses a tree-like structure and relational uses tables, network models use graphs to show essential connections.
  
  

  It's a more flexible modeling approach that can represent objects and the many relationships they share. Child, or member, nodes can have multiple parent, or owner, nodes.
  
  

  E-R
  
  

  Finally, there's the E-R model. E-R stands for entity-relationship. An E-R model aims to show the relationship between real-world entities. It sounds complicated, but this model is about creating entities, relationship sets, essential attributes, and constraints.
  
  

  The model might have a real-world entity, such as an employee, customer, or asset. Attributes are unique properties with values. They branch out from the entity to define the relationship between them.
  
  

  These types of data modeling methods are distinct. Each has advantages and disadvantages, and the right one can change depending on the data use case. A platform that provides modeling based on your needs can make things much easier to understand no matter how you use the data.
