ER/Studio 20.8が登場：AIを活用したデータモデリングの導入

Now available: ER/Studio 20.8, featuring the industry’s first AI assistant for logical data modeling.

Data modeling has often started with a blank canvas, vague requirements, and hours of effort translating business concepts into structured models. ER/Studio 20.8 changes that. With the new AI Modeling Assistant, users can enter business requirements in plain language and instantly generate a fully structured, metadata-rich logical model.

No dragging shapes. No translating business terms by hand. Just type what you need—ER/Studio builds the model for you.

How the AI Modeling Assistant Works

The assistant lives directly inside ER/Studio’s modeling workspace. You simply enter a description of what you need—a few lines of plain text, like:

“We need to track customers, their purchases, payment types, and delivery preferences.”

In seconds, the AI returns a fully structured logical model that includes:

• エンティティ
• 属性
• 人間関係
• Business terms and metadata

It’s editable. It’s integrated. And it’s built to extend seamlessly into your broader ER/Studio architecture. You’re no longer stuck building everything by hand. You’re free to refine, govern, and scale.

What Makes This a Game-Changer?

This isn’t just a productivity boost. This is a strategic shift in how modeling begins—especially for organizations adopting Data Product delivery or expanding data ownership beyond technical teams.

Here’s what sets the ER/Studio AI Modeling Assistant apart:

• Natural Language → Structured Models: Just describe your business concept. The AI turns it into a working logical model—on demand.
• Faster Time to First Model: No more blank canvas paralysis. Start with structure and iterate—faster than ever before.
• Business-First Modelin: Because the assistant understands business language, the model reflects your terminology—not just technical labels.
• Alignment from the Start: By capturing stakeholder language upfront, the AI reduces rework, miscommunication, and model-to-business drift.
• Built for Real Environments: The model isn’t locked in. It behaves just like any other model in ER/Studio—ready for extension, mapping, versioning, and governance.

Seamless, Familiar, Powerful

You don’t have to install anything new or learn another tool. The AI assistant is:

• Embedded in your ER/Studio modeling workspace
• Accessed via the new Model Prompt textbox
• Fully integrated with your glossary, lineage, and metadata environment
• Included in all editions of ER/Studio: Standard, Professional, and Enterprise
• Free to use until October 31st, 2025

Start typing. The model will follow. See it in action.

ER/Studio 20.7 Recap: Enhanced JSON Modeling and Governance Integration

While 20.8 introduces AI-powered modeling, the recent release of 20.7 focused on improving modeling precision and expanding governance integration—especially for teams working with JSON and Microsoft Purview.

JSONフィールドのサポート例

ER/Studio 20.7 added the ability to define example values for fields in JSON models. This enhancement helps users create more realistic, informative schemas that better support design clarity and documentation.

• Example values appear in JSON Instance generation (prioritized over default/reference values)
• JSON Schema generation includes default, example, and reference values
• Containment line cardinality and nested structures are now more accurately represented

These updates are especially useful for teams designing MongoDB structures or managing complex JSON configurations.

Microsoft Purview Integration Enhancements

In Team Server, ER/Studio now supports Business Domain glossary terms introduced in Microsoft Purview. This allows teams to align their modeling efforts with evolving data governance frameworks, including Data Mesh and domain-oriented design.

Additional improvements include:

• Support for multiple inheritance in Purview term relationships
• Simplified relationship mapping for improved model clarity
• Direct sync with Purview-assigned roles such as Data Steward and Catalog Reader

Together, these enhancements enable tighter alignment between ER/Studio models and Microsoft Purview’s governance capabilities—helping organizations maintain consistency across both technical metadata and business context.

Why These Releases Matter

Together, ER/Studio 20.7 and 20.8 deliver a powerful one-two punch:

• 20.7 gave architects more control over JSON and deeper alignment with Purview governance.
  
• 20.8 makes modeling faster, easier, and more collaborative through AI.

If you’ve ever wished data modeling could move at the pace of business, this is your moment. Whether you’re driving modernization, building a Data Mesh, or simply trying to keep up with the backlog, ER/Studio’s latest releases help you deliver faster—without losing structure.
