Dynamics 365 Dataverse: Store, Secure, and Build Apps from Core Business Data
Microsoft Dataverse is the intelligent data platform that underpins the entire Dynamics 365 and Power Platform ecosystem, providing a secure, scalable, and governed foundation for storing core business data and building enterprise applications. With 28+ years of Microsoft consulting experience, our team at EPC Group has architected Dataverse solutions for organizations ranging from mid-market companies to Fortune 500 enterprises across healthcare, finance, and government.
What Is Microsoft Dataverse?
Dataverse (formerly the Common Data Service) is a cloud-based, low-code data platform that enables organizations to securely store and manage business data used by Dynamics 365 applications, Power Apps, Power Automate, and Power BI. It provides a standardized schema of tables (formerly entities), columns, relationships, and business logic that eliminates the need to build custom databases for every business application.
At its core, Dataverse is built on top of Azure SQL Database and Azure Cosmos DB, giving it enterprise-grade performance, automatic scaling, and geographic redundancy. Every Dynamics 365 application -- whether Finance, Sales, Customer Service, or Field Service -- stores its data in Dataverse, creating a single source of truth across your entire business operation.
Core Capabilities of Dataverse
- Standard and Custom Tables: Dataverse includes over 400 standard tables (Account, Contact, Opportunity, Case, etc.) that follow the Common Data Model specification. You can extend these or create entirely custom tables to model your unique business data without writing a single line of SQL.
- Rich Data Types: Support for text, number, currency, date/time, lookup, choice, image, file attachment, and calculated columns. Formula columns (powered by Power Fx) allow Excel-like expressions that compute automatically.
- Relationships: One-to-many, many-to-one, and many-to-many relationships between tables with referential integrity enforcement, cascade rules, and automatic lookup resolution.
- Business Rules and Logic: Define server-side business rules that validate data, set default values, show/hide fields, and enforce business logic without code. These rules execute consistently whether data is entered through a model-driven app, canvas app, API, or data import.
- Calculated and Rollup Columns: Automatically compute values based on formulas or aggregate child records. For example, roll up all invoice line items to a total on the invoice header.
- File and Image Storage: Store documents, images, and attachments directly in Dataverse with configurable size limits up to 128 MB per file.
- Elastic Tables: For high-volume, low-latency scenarios (IoT data, telemetry, logs), elastic tables backed by Azure Cosmos DB handle millions of rows with sub-millisecond reads.
Enterprise Security in Dataverse
Dataverse provides the most granular security model of any low-code data platform, making it ideal for compliance-heavy industries:
| Security Layer | Description | Use Case |
|---|---|---|
| Security Roles | Assign CRUD permissions per table with organization, business unit, parent-child, or user-level scope | Role-based access (Sales Manager, Finance Analyst) |
| Business Units | Hierarchical organizational units that partition data visibility | Multi-division, multi-country organizations |
| Teams | Owner teams and access teams for group-based record sharing | Project teams, regional teams |
| Field-Level Security | Restrict read/write access to specific columns | SSN, salary, PHI data in HIPAA environments |
| Column Encryption | Encrypt sensitive columns at rest with customer-managed keys | PII, financial data, health records |
| Audit Logging | Complete audit trail of all data changes with user, timestamp, old/new values | SOC 2, HIPAA, regulatory compliance |
Building Applications on Dataverse
Dataverse serves as the foundation for three types of applications within the Microsoft ecosystem:
- Model-Driven Apps: Automatically generate full-featured business applications from your Dataverse data model. The UI is driven by the table structure, forms, views, and dashboards you configure -- no front-end coding required. These apps include navigation, search, filtering, record creation, and inline editing out of the box.
- Canvas Apps: Build pixel-perfect custom UIs using a drag-and-drop designer with Power Fx formulas. Canvas apps connect to Dataverse as a data source and support offline mode, barcode scanning, GPS, camera, and other mobile capabilities.
- Custom Pages: A hybrid approach that embeds canvas app components within model-driven apps for scenarios requiring both data-driven layouts and custom UI elements.
All three app types share the same Dataverse security model, ensuring consistent data governance regardless of how users access the data.
Integration and API Access
Dataverse exposes a comprehensive set of APIs for integration with external systems:
- Web API (OData v4): RESTful endpoints for CRUD operations, queries, and batch operations from any HTTP client.
- Organization Service (.NET SDK): Strongly typed .NET client for high-performance server-side integrations.
- Power Automate Connectors: Over 1,000 pre-built connectors enable no-code integration with Salesforce, SAP, Oracle, ServiceNow, and hundreds of other platforms.
- Azure Synapse Link: Continuously replicate Dataverse data to Azure Synapse Analytics for large-scale reporting, data warehousing, and machine learning without impacting the operational database.
- Virtual Tables: Present external data (SQL Server, SharePoint, Azure SQL) as native Dataverse tables without data movement, enabling real-time access within apps and workflows.
- Dataverse Webhooks and Service Bus: Event-driven integration for real-time notifications when data changes.

Frequently Asked Questions
What is the difference between Dataverse and a traditional SQL database?
Dataverse is a managed platform built on Azure SQL that adds security roles, business logic, audit logging, API endpoints, and a standardized data model on top of the raw database engine. Unlike a traditional SQL database where you manage schemas, backups, scaling, and security yourself, Dataverse handles all of this automatically. You define tables, columns, and relationships through a visual designer or solution files, and the platform handles indexing, replication, and compliance.
How much data can Dataverse handle?
Dataverse includes a base capacity of 10 GB per tenant with additional capacity available through add-on licenses. Standard tables can handle tens of millions of rows with proper indexing. For high-volume scenarios requiring billions of rows (IoT, telemetry, event logs), elastic tables backed by Azure Cosmos DB provide virtually unlimited horizontal scaling with sub-millisecond latency.
Is Dataverse compliant with HIPAA and SOC 2?
Yes. Dataverse holds HIPAA BAA coverage, SOC 1 and SOC 2 Type II attestations, FedRAMP High authorization, ISO 27001/27017/27018 certification, and over 90 other compliance certifications. Field-level security, column encryption with customer-managed keys, and comprehensive audit logging make it suitable for storing PHI, PII, and financial data in regulated industries.
Can we use Dataverse without Dynamics 365?
Yes. Dataverse can be licensed independently through Power Apps per-app or per-user plans without requiring any Dynamics 365 licenses. This makes it ideal for building standalone business applications with Power Apps and Power Automate. You also get a limited version called Dataverse for Teams included with Microsoft 365 licenses, though it has reduced capacity and feature limitations.
How do we migrate data from our existing systems into Dataverse?
EPC Group uses multiple migration approaches depending on the source system and data volume. For smaller datasets, the built-in Excel import or the Dataverse connector in Power Automate works well. For large-scale migrations from SAP, Oracle, or legacy SQL databases, we use Azure Data Factory pipelines with custom transformation logic. We always perform a pilot migration, data validation, and reconciliation before the final cutover to ensure accuracy.
