16. Data Warehouse Intro
Facts & Dims

17. Facts & Dimensions Fact Table Dimension Table
[AdventureWorksDW2014].[dbo]. [FactResellerSales]
[AdventureWorksDW2014].[dbo].[DimEmployee]
Consists of the measurements, metrics or facts of a business process
Calculations can be done on the measures (e.g. sum, count, min, max)
Provides filtering, grouping and labelling

Specifying the full connection string using the full ADO.NET or JDBC connection string. or
Specifying server, username, password, and database name.
Connect Using File command
A file contains the connection information, therefore can be environment related.

Check Data Warehouse table DimCustomer count record against a fixed value in FitNesse wiki page.

21. Count Data Warehouse Records
Query command with fixed result
Brittle test due to the fact this test requires updating every time test data changes as the DimCustomer table record will change.
Which SQL for COUNT and why?

22. Count Data Warehouse Records table FactInternetSales

TOP 3
Return results in the same order. ORDER BY 1, 2
(or else missing records will be displayed)
