01
Stage 1 – Sales Data Collection
Process
The organization collects sales information from its business systems.
Tools
Cloud S3
Cloud Lambda
Implementation
Sales data containing information such as customer, product, quantity, price, region, and sales date is uploaded to the application. The system receives the data and stores the raw sales records for further processing.
02
Stage 2 – Sales Data Validation
Process
The system checks whether the incoming sales data is complete and valid.
Tools
Cloud Lambda
Implementation
The system checks required fields such as product ID, customer ID, quantity, sales amount, and transaction date. Invalid or incomplete records are identified and separated from valid sales records.
03
Stage 3 – Data Cleaning
Process
The system removes duplicate and inconsistent sales records.
Tools
Cloud Lambda
Cloud S3
Implementation
The application identifies duplicate transactions, missing values, incorrect formats, and inconsistent records. Valid data is retained for further processing while invalid records are separated for review.
04
Stage 4 – Data Transformation
Process
Raw sales data is converted into a standardized format.
Tools
Cloud Lambda
Cloud S3
Implementation
The application standardizes values such as dates, currencies, product information, and sales categories. The transformed records are prepared for aggregation and analysis.
05
Stage 5 – Sales Data Aggregation
Process
The system combines processed sales records to generate useful business summaries.
Tools
Cloud Lambda
PostgreSQL
Implementation
The application calculates values such as total sales, total quantity, average sales, and revenue based on product, region, customer, and time period.
06
Stage 6 – Processed Data Storage
Process
The transformed and aggregated sales information is stored for future analysis.
Tools
PostgreSQL
Cloud S3
Implementation
Detailed processed sales records and aggregated results are stored in the appropriate data storage. PostgreSQL maintains structured sales information, while S3 can retain raw and processed datasets.
07
Stage 7 – Sales Analysis
Process
Managers and business users analyze the processed sales information.
Tools
PostgreSQL
Implementation
The application retrieves aggregated sales information and provides insights such as regional sales performance, product performance, monthly revenue, and customer sales.
08
Stage 8 – Sales Reporting
Process
The organization generates sales reports for management and business teams.
Tools
PostgreSQL
Cloud Lambda
Implementation
The application retrieves the required processed data and generates reports such as daily sales, monthly revenue, product-wise sales, region-wise sales, and customer-wise sales.
09
Stage 9 – Data Processing Completion
Process
The transformed and aggregated data becomes available for business decision-making.
Tools
Cloud Lambda
PostgreSQL
Implementation
After all processing stages are successfully completed, the system marks the data-processing workflow as completed and makes the latest sales information available to authorized users.
