Your industrial supply company wants to create a data warehouse where management can obtain a single corporate-wide view of critical sales information to identify bestselling products, key customers, and sales trends. Your sales and product information are stored in two different systems: a divisional sales system running on a UNIX server and a corporate sales system running on an IBM mainframe.
You would like to create a single standard format that consolidates these data from both systems. Identify the primary key of MPD. Sales table. (10 points) Using Figure 5.10 in your text as an example, create a SQL Select Query to pull Product_ID, Product_Description and Units_Sold for Product 85773 from the CSS.Sales table. Hint: do not use the CSS prefix in your query. (10 points) Identify the data problems that must be resolved as you determine the system of record for each of the attributes in the proposed data warehouse. Who should make those decisions, the database specialist or the business manager leading this data warehouse project? Why? (10 points) What business problems are created by having two disparate sales systems? (10 points) List and describe how each of the five business intelligence reports covered in section 10.2 of your text will leverage the information below to provide actionable information. (10 points) Sample data warehouse layout for this company. You are not required to fill out this table. Proposed Data Warehouse Format Product_ID, Product_Description, Cost_Per_Unit, Units_Sold, Sales_Region, Division, Customer_ID. Answer the five questions in a Word Document and attach it to this assignment content area.

Paper For Above instruction
The creation of a comprehensive data warehouse for an industrial supply company necessitates careful planning, data integration, and understanding of both technical and business aspects. Central to this process is analyzing the primary key of the MPD sales table, crafting SQL queries to extract relevant data, resolving data quality issues, and understanding the implications of managing disparate systems. Additionally, leveraging business intelligence reports to turn data into actionable insights is critical for strategic decision-making.
Primary Key of MPD Sales Table
The primary key in the MPD sales table uniquely identifies each record. Typically, in sales databases, this key is composed of attributes that, in combination, guarantee uniqueness for each transactional record. Commonly, this would include a Sales_ID or Transaction_ID. If the table is structured with a composite key, it may involve multiple fields such as Sales_Date, Store_ID, and Transaction_Number. Based on standard conventions, the primary key identified in the MPD sales table is likely to be a unique Transaction_ID that distinctly records each sale. Recognizing this ensures data integrity when integrating datasets from different systems.
SQL Query to Retrieve Specific Sales Data
Using Figure 5.10 in the text as a reference for constructing SQL queries, the task is to retrieve information on Product 85773 without prefixing the table name because of the context of the query. The SQL statement should select Product_ID, Product_Description, and Units_Sold from the CSS.Sales table with a filter applied. The query would be:
SELECT Product_ID, Product_Description, Units_Sold
FROM Sales
WHERE Product_ID = 85773;
This simple query extracts the desired product information, which is useful for sales analysis or inventory management. It illustrates fundamental SQL syntax where the SELECT clause specifies the columns of interest, the FROM clause indicates the table, and the WHERE clause restricts the results to the specified product.
Data Problems and Decision-Making Responsibilities
When consolidating data from the sales and product systems, several data quality issues need resolution. These include inconsistencies in data definitions, formats, and levels of detail. For example, product descriptions may differ between systems, units sold might be recorded with different units or timeframes, and regional names might not be standardized. Resolving such issues is crucial to avoid misinterpretation of data and ensure accurate reporting.
Decisions regarding data quality and system of record should primarily involve business managers rather than solely technical staff. Business managers understand the context, importance, and usage of data for strategic initiatives. They can determine which system's data is more accurate or authoritative for each attribute. While database specialists aid in implementing these decisions, the business side ensures that data standards align with organizational goals and operational realities.
Business Problems from Disparate Sales Systems
Having two disparate sales systems creates several issues. Firstly, it leads to data fragmentation, making it challenging to obtain a holistic view of sales performance. Inconsistent data formats and definitions complicate data integration, risking inaccuracies in reports. It also increases operational complexity and cost due to duplicate data maintenance, synchronization issues, and higher chances of errors. Furthermore, decision-makers lack quick, reliable access to comprehensive sales insights, impairing responsiveness to market changes or customer needs.
Leveraging Business Intelligence Reports for Actionable Insights
Section 10.2 of the text describes several BI reports that can add value when leveraging integrated sales data:
- Production Reports: These reports track manufacturing output against sales, helping identify production efficiency issues or inventory excess. By analyzing units sold and production costs, managers can optimize manufacturing schedules and reduce wastage.
- Sales Performance Reports: These display key sales metrics such as total units sold, revenue, and profit margins by product, region, or salesperson. They enable management to identify top-performing products and regions, guiding resource allocation.
- Customer Reports: Focused on customer buying patterns, these reports reveal key accounts and purchasing frequency. Recognizing high-value customers helps in targeting loyalty programs and personalized marketing.
- Market Trend Reports: Analysis of sales trends over time assists in forecasting and identifying emerging market opportunities or downturns, enabling proactive strategic planning.
- Operational Efficiency Reports: These evaluate processes by comparing sales data with production and supply chain data, highlighting bottlenecks and areas for cost reduction.
By integrating data across the systems, these reports can provide managers with timely, accurate information to make evidence-based decisions that enhance operational effectiveness, customer satisfaction, and profitability.
Conclusion
Building a data warehouse from disparate sales systems involves resolving fundamental data issues, establishing authoritative data sources, and designing reports that translate data into actionable insights. The process requires collaboration between technical staff and business leaders to ensure data quality and relevance. Properly leveraged, business intelligence reports derived from a unified data model can support strategic initiatives, optimize operations, and drive competitive advantage in the industrial supply sector.
