Remarks

MsSqlServerStorage connects to SQL server using the .NET Framework Data Provider for SQL Server (System.Data.SqlClient Namespace).

The storage needs a host database with specific tables and stored procedures which may be created in dedicated or shared database. The necessary SQL objects may be created using the DatabaseCacheConfigurator tool (located under the Telerik Reporting installation folder / Tools) or manually executing the follow DDL script. It adds all needed objects to an existing MS SQL database (execute in the context of existing database):
