This sample contains databases as well as a number of sample scripts and workload drivers.
The sample databases are created through SQL Server Data Tools projects in Visual Studio. Each database has its own project; the solution wwi-sample.sln in the root folder of the sample has references to all the projects. To load all project in the solution, SQL Server Integration Services and SQL Server Analysis Services need to be installed on the machine.
The sample scripts are available as Transact-SQL. The workload drivers are sample applications created in Visual Studio.
The source code for the sample is further structured as follows:
Sample Power BI dashboards that leverage the WideWorldImporters and WideWorldImportersDW databases.
Sample scripts that illustrate the use of various SQL Server features with the WideWorldImporters sample database.
Simple apps that simulate workloads for the WideWorldImporters sample database.
SQL Server Data Tools project for the OLAP database WideWorldImporters.
SQL Server Analysis Services Multidimensional project to create the Analysis Services database WWI-SSASMD.
SQL Server Data Tools project for the main OLTP database WideWorldImporters.
SQL Server Integration Services (SSIS) project for the Extract, Transform, and Load (ETL) process that takes data from the transactional database WideWorldImporters and loads it into the WideWorldImportersDW database.
The code included in this sample is not intended to be used for production purposes.
