Part 2:

Query 1: Aggregate Number of Children

Graph and Data:

Explanation: This graph demonstrates what the correlation between the total amount of children the and the amount of sales that particular group completes. After analyzing the graph you see a trend that people with fewer children seem to be spending a lot more on the internet, this should be noted when developing a plan to seek what type of people to advertise to.

Code:USE [AdventureWorksDW2012];SELECT [OrderQuantity], [TotalChildren],SUM ([OrderQuantity]) as [Order Quantity],SUM ([SalesAmount]) AS [Total Sales],AVG ([SalesAmount]) AS [Average Sales]FROM [dbo].[DimCustomer] AS C inner join [dbo].[FactInternetSales] AS FON C.CustomerKey = F.CustomerKey

GROUP BY [TotalChildren], [OrderQuantity]ORDER BY [TotalChildren] ASC

Query 2: Aggregate Age

Graph and Data:

Explanation: This graph shows the difference between age and the amount of sales the person has. As you can tell by the graph, people within the 40-60 range spend the most money on sales in this company.

Code:USE [AdventureWorksDW2012];SELECT [OrderQuantity], [BirthDate] ,DateDiff (YEAR, [BirthDate], GETDATE()) AS [Age],SUM ([OrderQuantity]) as [Order Quantity],SUM ([SalesAmount]) AS [Total Sales],AVG ([SalesAmount]) AS [Average Sales]FROM [dbo].[DimCustomer] AS C inner join [dbo].[FactInternetSales] AS FON C.CustomerKey = F.CustomerKey

GROUP BY [BirthDate], [OrderQuantity]ORDER BY [BirthDate] ASC

Query 3: Aggregate Gender

Data and Graph:

Explanation: This data and graph is aggregated to show the total sales between men and females and the amount of sales that they produce. When examining the data and graph one could see the females slightly own the market but at the same time men are very close and marketing should be focused on both genders.

Code:USE [AdventureWorksDW2012];SELECT [OrderQuantity], [Gender] ,SUM ([OrderQuantity]) as [Order Quantity],SUM ([SalesAmount]) AS [Total Sales],AVG ([SalesAmount]) AS [Average Sales]FROM [dbo].[DimCustomer] AS C inner join [dbo].[FactInternetSales] AS FON C.CustomerKey = F.CustomerKey

GROUP BY [Gender], [OrderQuantity]ORDER BY [Gender] ASC

Query 4: Aggregate Education Level

Data and Graph:

Explanation: This data and graph shows the distribution of sales based on the markets education. For the most part people with a bachelor’s degree are the highest and marketing tactics should be adjusted for this demographic.

Code:USE [AdventureWorksDW2012];SELECT [OrderQuantity], [EnglishEducation] ,SUM ([OrderQuantity]) as [Order Quantity],SUM ([SalesAmount]) AS [Total Sales],AVG ([SalesAmount]) AS [Average Sales]FROM [dbo].[DimCustomer] AS C inner join [dbo].[FactInternetSales] AS FON C.CustomerKey = F.CustomerKey

GROUP BY [EnglishEducation], [OrderQuantity]ORDER BY [EnglishEducation] ASC

Query 5: Aggregate Marital Status

Data and Graph:

Explanation: This graph shows the difference between marital status and sales, in general it seems that people who are married usually make up more sales. But I should also be noted that people that are single also make up a large portion of this market.

Code:USE [AdventureWorksDW2012];SELECT [OrderQuantity], [MaritalStatus] ,SUM ([OrderQuantity]) as [Order Quantity],SUM ([SalesAmount]) AS [Total Sales],AVG ([SalesAmount]) AS [Average Sales]FROM [dbo].[DimCustomer] AS C inner join [dbo].[FactInternetSales] AS FON C.CustomerKey = F.CustomerKey

GROUP BY [MaritalStatus], [OrderQuantity]ORDER BY [MaritalStatus] ASC

Query 6: Aggregate Title

Data and Graph:

Explanation: This graph is meant to show the title of the purchaser and how much they make up in sales. It seems that most people do not use titles anymore should that could be taken into account when one is to try and aggregate this data.

-Code:USE [AdventureWorksDW2012];SELECT [OrderQuantity], [Title] ,SUM ([OrderQuantity]) as [Order Quantity],SUM ([SalesAmount]) AS [Total Sales],AVG ([SalesAmount]) AS [Average Sales]FROM [dbo].[DimCustomer] AS C inner join [dbo].[FactInternetSales] AS FON C.CustomerKey = F.CustomerKey

GROUP BY [Title], [OrderQuantity]ORDER BY [Title] ASC
