dbo is the "default" schema for SQL Server;(database owner)

Dimension TableFact Table[AdventureWorksDW2014].[dbo]. [FactResellerSales]

• 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

Worked Examples

Specifying server, username, password, and database name.

Connect Using File commandA file contains the connection information, therefore can be environment related.

Which SQL for COUNT and why?

Brittle test due to the fact this test requires updating every time test data changes as the DimCustomer table record will change.

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

Lets Change Focus

Test Database

Data Warehouse

[DbFitNesseTest]

Test Database

Data Warehouse

Test Database is used for:• Store Test data (either as a source or created from other sources)• Store procedures (to be executed from FitNesse)• Storing results (to compare in the future)
