This document summarizes the implementation of a data warehousing project using SQL. It includes requirements analysis, database diagrams, and SQL scripts to create dimension and fact tables. The tables created include Vendor, Products, Inventory, Transactions, and Retailer dimensions and a Product fact table. Extract, transform, load processes are implemented using SQL Server Integration Services packages to stage and migrate data. The goal is a proof of concept for a data warehouse to track inventory, orders, and transactions.

- 1. IMPLEMENTING DATAWAREHOUSING USING SQL Project By- Sushil Kasar. Chandan Jha. Note:-This project is based on scenario given by our Institution ,you can refer the data_source files below.
- 5. Added Graphs showing the Net Savings.
- 10. Database_Daigram
- 13. Creating packages using SSIS. Staging and Migrating. A Proof of Concept.
- 22. SQL scripts • Create table Vendor_Dim ( Vendor_key int constraint pk_k primarykey, Vendor_name nvarchar(255), Vendor_Address nvarchar(255), Vendor_phone int, Vendor_state nvarchar(255) ) • Select * from Vendor_Dim --------------------------------------------------------------------------------------------------------- ----
- 23. Create table Products_vendor_Dim ( Product_vendor_key intconstraint Pk_pv primarykey, Unit_selling_price int, Discount int, Desired_Lead_time int ) select*from Products_vendor_Dim
- 24. • Create table products_Dim ( product_key int constraint Pk_P primarykey, Product_name nvarchar(255), Subcategory nvarchar(255), Qty_Per_unit nvarchar(255), Unit_cost_price int, Unit_selling_price int, ReOrder_Level int, ReOrder_Qty int, Qty_on_Hand int ) select*from products_Dim
- 25. Create table Inventory_Issued_Dim ( Inventory_Issued_key int constraint Pk_II primarykey, Qty_Issued int, date_issued date, Issued_By nvarchar(255), Issued_to nvarchar(255) ) Select * from Inventory_Issued_Dim
- 26. createtable Inventory_Ordered_Dim ( Inventory_Ordered_key int constraint Pk_IO primarykey, Date_Ordered date, Date_Received date, Lead_Time int, Qty_Ordered int, Qty_Received int, Unit_Cost_Price int, Qty_Deficit int, Discount int, After_Discount_Price int ) Select * from Inventory_Ordered_Dim
- 27. • createtable Transaction_QOH_Dim ( Transaction_QOH_Key intconstraint Pk_T primarykey, Closing_QOH int, Opening_QOH int, Transacted_Date date, Issued_to nvarchar(255) ) • Select * from Transaction_QOH_Dim • Create table Retailer_dim ( Retailer_Key intconstraint pk_R primarykey, Retailer_Name nvarchar(255), Retailer_Address nvarchar(255), Retailer_Phone int, Retailer_state nvarchar(255), Retailer_country nvarchar(255) ) • Select * from Retailer_dim
- 28. Createtable Product_fact ( Vendor_key intconstraint fkVendorkey foreignkeyreferences Vendor_Dim(vendor_key), Product_vendor_key int constraint fkPvKey foreign key references Products_Vendor_Dim(Product_vendor_key), Product_key int constraint fkP foreign key references Products_Dim(Product_key), Inventory_Issued_key int constraint fkII foreign key references Inventory_Issued_Dim(Inventory_Issued_Key), Inventory_Ordered_key int constraint fkIO foreign key references Inventory_Ordered_Dim(Inventory_Ordered_Key), Transaction_QOH_Key int constraint fkt foreign key references Transaction_QOH_Dim(Transaction_QOH_Key), Retailer_Key int constraint fkR foreign key references Retailer_Dim(Retailer_Key) ) • Select * from Product_fact
