Top 8 Data Modeling Best Practices for Data-Driven Enterprises

A solid understanding of data modeling best practices can help ensure data-driven enterprises get maximum value from their data modeling projects. 

Data modeling is an important technique that helps data-driven businesses cope with the challenges of managing data resources effectively. 

When it is performed efficiently, data modeling can provide tangible business benefits by allowing organizations to handle big data assets productively. 

Data modeling is used extensively in database creation and to provide the foundation for data governance initiatives. The quality of the data models used in various activities has an enormous impact on the end product. Poorly constructed models will not help accomplish the goals for which they were developed. 

What Makes a Good Data Model?

Good data models share several characteristics that set them apart from those that provide less value to their creators. Ensuring that your data models conform to a set of standards will go a long way toward developing useful artifacts that further enterprise business goals. 

Following are the top 8 data modeling best practices that go into creating good data models …

Top 8 Best Practices for Data Modeling

  • Obtaining a clear understanding of the business requirements and expected results is a mandatory first step when creating data models. Without this knowledge, it is virtually impossible to develop useful models.
  • Use data visualization techniques to gain a different perspective on the data elements that will be incorporated into the model. This practice can help reduce redundancy and assist in developing more consistent models.
  • Begin with simple and extensible models. Minimizing the complexity in the early stages of development allows you to concentrate on the model’s accuracy. Once the initial model is verified, more data elements can be added to extend it.
  • Define business requirements in terms of facts, dimensions, filters, and order to create models that can answer the questions posed by end-users.
  • Restrict the model’s complexity by only using the data elements needed to address requirements. Incorporating extraneous data into models can lead to waste and degraded performance.
  • Verify each stage of data model development before proceeding with the next phase. For example, performing testing to ensure the proper primary keys have been chosen can help reduce the complexity of many-to-many relationships that contribute to unmanageable data models. 
  • Look for causal relationships between data elements that can be incorporated into data models. The difference between the correlation of data components and the causation of their behavior are important distinctions that need to be reflected in the associated models.
  • Allow data models to evolve to address changes in data sources or business requirements. Storing models in an accessible repository and using a consistent data dictionary facilitates the creation of models that can be updated when circumstances demand.

Approaching data modeling with these factors in mind will result in more effective models that add value to data-driven businesses.
