The following is a SharePoint Dictionary word of the day: Application Model.
In the world of SharePoint and Business Data Connectivity (BDC) Services, the application model plays a quiet but powerful role. It's the structural engine that organizes, transports, and standardizes how external data enters and moves through your SharePoint environment. For AdSense‑optimized content, this topic is gold: high‑intent readers, enterprise‑focused keywords, and strong search demand around integration, governance, and SharePoint architecture.
What Is an Application Model in BDC?
At its core, an application model is an object within SharePoint's Business Data Connectivity Services that contains:
- One or more external content types
- The properties, metadata, and configuration those content types rely on
- The structure needed to import or export these definitions across environments
- Think of it as a portable container that holds everything SharePoint needs to understand and interact with external systems - SQL databases, CRM platforms, ERP systems, line‑of‑business apps, and more.
Why Application Models Matter
The BDC application model is essential for organizations that depend on external data. Here's why:
- Consistency across environments - Move external content types from dev → test → production without rebuilding connections.
- Governance & compliance - Centralize definitions to ensure data access rules and metadata remain uniform.
- Scalability- Add new external systems or update existing ones without re‑architecting your entire SharePoint farm.
- Faster deployments - Import/export models as XML packages, reducing manual configuration time.
- For enterprises with complex data landscapes, this is a massive operational advantage.
How Application Models Work
- An application model bundles together:
- External content types (ECTs)
- Connection properties
- Authentication modes
- Metadata definitions
- Operations (CRUD, filters, identifiers)
When imported into BDC Services, SharePoint instantly understands:
- What the external system is
- How to connect
- What operations are allowed
- How data should be displayed in lists, web parts, and search
- This makes the BDC metadata store a powerful integration hub.
Importing & Exporting Application Models
One of the biggest strengths of the application model is portability. Administrators can:
- Export a model as a .bdcm file
- Import it into another SharePoint environment
- Version and maintain models as part of DevOps pipelines
- This is especially valuable for organizations using hybrid or multi‑farm architectures.
- Real‑World Use Cases
- Integrating SQL Server customer records into SharePoint lists
- Surfacing ERP inventory data in dashboards
- Connecting CRM systems for unified sales reporting
- Powering search results with external business data
- Automating workflows that depend on external line‑of‑business systems
Anywhere external data needs to appear inside SharePoint, the application model is the foundation.
Final Takeaway
The application model is more than a technical artifact - it's the blueprint that enables SharePoint to communicate with the outside world. By packaging external content types and their properties into a reusable, portable structure, it empowers organizations to scale integrations, maintain consistency, and accelerate deployments.
