Database Warehouse Helpproject 2 Practice1adventure Works Cycles Is

Develop an OLAP Cube based on the AdventureWorksDW2012 data warehouse, including all dimensions, attributes, measures, and calculated fields as specified. Create a date dimension with hierarchy and relationships, format measures properly, add a calculated measure for TotalCost, and deploy the cube. Use SQL Server Management Studio to verify the cube's population, displaying Product Name, Year, UnitsBalance, and TotalCost. Additionally, create a KPI named "Availability" with traffic light indicators based on UnitBalance, and demonstrate its functionality within the Cube Browser for specific product and date selections. Include relevant snapshots and a comprehensive report with your name and the required images.

Paper For Above instruction

Adventure Works Cycles, a prominent multinational bicycle manufacturer, operates within a complex business environment that necessitates robust data analysis capabilities. To address this need, the development of an Online Analytical Processing (OLAP) cube based on the AdventureWorksDW2012 data warehouse becomes essential. This initiative will facilitate multidimensional analysis of sales, inventory, and product-related data, providing valuable insights for decision-making processes.

Part A: Designing and Deploying the OLAP Cube

The first step involves constructing an OLAP cube that encapsulates all relevant dimensions, attributes, and measures from the data warehouse structure described. The core fact table for this development is the FactProductInventory, which contains key performance indicators like inventory movement and units in/out. The dimensions to be incorporated include DimProduct and DimProductSubcategory, each providing granular contextual information about products and their categories.

To build this cube, the process begins within SQL Server Analysis Services (SSAS). Choosing FactProductInventory as the data source, the DateKey attribute must be transformed from an integer to a date-formatted attribute. This is accomplished via a calculated column using the expression: SUBSTRING(CONVERT(CHAR(8), OrderDateKey), 1, 4) to extract the year, and similarly for the month as SUBSTRING(CONVERT(CHAR(8), OrderDateKey), 5, 2). These are then used to develop a date hierarchy with Year, Month, and Day levels, setting their relationships as rigid to preserve integrity.

The Date dimension should have its attribute type altered appropriately, with the DateKey renamed to Date and set to invisible to declutter the cube interface. Attributes for product details, such as Product Name, Color, Size, and other descriptive data in DimProduct, are to be added but kept invisible to streamline the user experience.

A new calculated measure named TotalCost is created as the product of UnitCost from the dimension table and UnitsBalance from the fact table, formatted accordingly for currency or number display. Measures like UnitsIn, UnitsOut, and UnitsBalance should be formatted with appropriate aggregate functions and string formatting to enhance readability.

The product hierarchy is established within DimProduct, setting relationships as rigid to ensure stable navigation. This hierarchy typically includes Product Category > Product Subcategory > Product Name, allowing users to analyze data across different levels of product detail. The dimension usage configuration explicitly links DimDate with the fact table, with correct relationship attributes verified and tested.

Subsequently, the project must be deployed with correct settings, establishing connections to the database server and ensuring the cube is processed successfully. Once deployed, a snapshot of the cube view displaying Product Name against Years, with measures UnitsBalance and TotalCost, should be captured for documentation.

Using SQL Server Management Studio, verify the populated cube by querying the data, ensuring all relationships and measures are accurate and functional.

Part B: Creating and Demonstrating the KPI

The second phase involves defining a KPI named Availability, based on the UnitsBalance measure within the cube. The KPI categorizes inventory status with traffic light indicators: red for negative UnitsBalance (0). These thresholds support quick visual assessment of inventory health.

The KPI setup involves specifying the Value, Target, and Status expressions and configuring threshold values accordingly. The KPI is then demonstrated through the Cube Browser by selecting a particular product and viewing the Availability status for a specific year and month. Capturing screenshots of these views provides visual evidence of the KPI’s functionality.

Throughout the process, detailed visual documentation—including cube snapshots and KPI demonstrations—is essential for a comprehensive project report. This report should include a title page with the student's name, detailed descriptions of the steps taken, and all accompanying images to substantiate the cube's development and KPI functionality.

In conclusion, this project synthesizes data warehouse modeling, cube development, and KPI creation within SQL Server Analysis Services to empower Adventure Works Cycles with advanced analytics. The resulting cube enables multidimensional analysis of inventory and sales data, facilitating informed strategic decisions vital for competitive advantage in the bicycle manufacturing industry.
