Microsoft has added LocalDB support in .NET Framework 4. LocalDB is a free developer edition of SQL Server “Denali” meant to provide most of the server’s API but without management overhead.
Microsoft announced that the next version of SQL Server, known by the codename "Denali", will be called SQL Server 2012. It will feature the big data capabilities of Apache Hadoop and Power View, a touch-based business intelligence tool.
Solutions Design has released ORM Profiler, a tool meant to help improve data access layer performance. It tracks and logs ADO.NET calls so that developers can analyze their data access and discover potential problems.
Denali will be the final edition of SQL Server to support OLE DB, because Microsoft considers ODBC to be the industry standard for relational data access.
SQL Server Development Tools (SSDT) - ‘Juneau’ - brings testing, debugging, version control, refactoring, dependency checking, and deployment to database development in Visual Studio. It was previewed recently along with SQL Server ‘Denali’ CTP.
SQL Server Denali includes a new type of table called FileTable, which builds on FileStream functionality. FileTable is meant for storing and managing unstructured data in SQL Server, while also making it accessible via the file system.
Microsoft recently announced CTP 3 for SQL Server ‘Denali’, which boasts of improved BI capabilities like Self Service Alerting, Self Service Reporting, improved Office integration, SharePoint Shared Service, better VS Tooling for developers and more.
