Join us to learn what it takes to expose relational data from a SQL Server Azure database as oData. This data can then be consumed as an external data source and queried just like any other related object within Salesforce. We'll focus on what you need to know to work with the read-only (for now) data and what you might need to change when two-way data communication is allowed.
