InterSystems states that Caché supports at least three data models – relational, object and hierarchical (globals). On can work with data presented in relational model in a program written on C# the same way one works with any other relational DB. To work with data presented by object model in C# one needs to use .NET Managed Provider or some kind or ORM. And starting with version 2012.2 one can work directly with globals (or use direct access to hierarchical data) via Caché eXTreme for .NET

Presenter: Jeff Semmens
Task: Model and access data as objects in .NET without designing the database first
Approach: Use InterSystems Entity Framework
 

Description: Come and experience how you can design your database model in .NET and evolve it over time by leveraging the Entity Framework.

Problem: Current bindings require database-first design. I cannot design my model in .NET.

Solution: The Entity Framework is an object-relational mapping framework that allows data-oriented applications to model and access their data as objects in .NET. Database- first is still supported but will fade away in future releases.
