Data Modeling Tools

Data modeling has always been the best way to understand complex data sources and automate design standards and integrity rules. Today, the role of data modeling has expanded as the central point of collaboration between data generators, stewards and consumers. That’s because data modeling is the best way to visualize metadata, and metadata is now the heart of enterprise data management, as well as data governance and intelligence efforts.

What Is a Data Model?

What is a data model?

A data model is a visual representation of data elements and the relationships between them. Data models help business and technical resources collaborate in the design of information systems and the databases that power them. They show what data is required and how it needs to be structured to support various business processes.

There are three basic types of data models, each with a specific purpose:

What is data modeling?

Data modeling is the process of creating a data model to communicate data requirements, documenting data structures and entity types. It serves as a visual guide in designing and deploying databases with high-quality data sources as part of application development.

Data modeling has been used for decades to help organizations define and categorize their data, establishing standards and rules so it can be consumed and then used by information systems. Today, data modeling provides even greater value because critical data exists in both structured and unstructured formats and lives both on-premises and in the cloud. So it’s a cost-effective and efficient way to manage and govern massive volumes of data, aligning data assets with the business functions they serve. You can automatically generate data models and database designs to increase efficiency and reduce errors to make the lives of your data modelers – and other stakeholders – much more productive.

Benefits of data modeling

You can’t manage what you can’t see. That’s why data modeling is a critical component of metadata management, data governance and data intelligence. It provides an integrated view of conceptual, logical and physical data models to help business and IT stakeholders understand data structures and their meaning. Data modeling is the first step to ensuring mission-critical information is used, understood and trusted across the enterprise. The primary benefits of data modeling software are the abilities to:

Discover, standardize and document existing data sources for visualization and analysis; also design and deploy high-quality data sources across disparate platforms

Use data models to migrate and re-deploy database structures to new database management systems and platforms

Visually compare, analyze and synchronize data models with deployed data assets

Support expanding regulatory requirements, such as GDPR and CCPA

Empower employees with self-service access for enterprise data capability, literacy and accountability

Govern data modeling teams, processes, portfolios and lifecycle to support expanding regulatory requirements

Author and integrate active data governance constructs, metadata configurations and stakeholder feedback to simplify collaboration across key roles and improve alignment

Improve business processes for operational efficiency

Data modeling tools have proved that if you take the time and make the investment upfront, you avoid the pain of costly mistakes further along in the development process. So the data model is a low-risk, low-cost capability that supports many use cases, including:

  • Database design and deployment with schema maintenance
  • Master data management design and data integration
  • Metadata management
  • Analytics/business intelligence design and data source analysis
  • Data warehouse and data lake design/documentation
  • Big Data adoption
  • DBMS rationalization and migration
  • Data governance
  • Data intelligence
