Windows Service for Notifier and SQL Backend Update
Budget: ₹400 – ₹750 INR
Project Overview
1.1. Objective
To design and develop a Windows service that automates sending emails and updating SQL backend database.
1.2. Scope
This project document outlines the requirements, architecture, design, implementation, and testing strategy for the Windows service.
Requirements
2.1. Functional Requirements
2.1.1. Email Sending
The service must be able to send emails using SMTP protocol.
The service should be able to fetch email recipients, subject, and content from the SQL database.
The service should be able to handle email attachments.
The service should provide support for multiple email providers (e.g. Gmail, Outlook,yahoo, smartermail etc.).
The service should support retry mechanism for failed email sending.
2.1.2. SQL Backend Update
The service should be able to connect to SQL backend database.
The service should be able to fetch data from database tables as per the specified query.
The service should be able to update the status of sent emails in the SQL database.
The service should be able to log errors and exceptions in a separate table in the database.
2.2. Non-Functional Requirements
2.2.1. Performance
The service should have low memory and CPU usage.
The service should be able to handle a high volume of email sending and database updates.
2.2.2. Security
The service should have proper authentication mechanisms to connect to the SQL database.
The service should use encrypted communication for email sending (e.g. SSL/TLS).
Architecture and Design
3.1. Architecture
The service will be developed using .NET Framework.
The service will use SQL Server as the backend database.
3.2. Components
3.2.1. Email Service
Responsible for sending emails using SMTP protocol.
Handles email content, recipients, and attachments.
3.2.2. Database Access Layer
Responsible for connecting to the SQL database.
Handles fetching data and updating the database.
3.2.3. Scheduler
Responsible for triggering the email sending and database update operations periodically.
Implementation
4.1. Technologies and Tools
Programming Language: C#
Development Environment: Visual Studio
Database: SQL Server
4.2. Development Steps
Design the database schema for email data and logs.
Develop the database access layer using C# and ADO.NET.
Develop the email service component with SMTP support.
Implement the scheduler to trigger email sending and database update operations.
Implement proper error handling and logging mechanisms.
Develop a configuration mechanism for SMTP settings and database connection strings.
Testing
5.1. Test Scenarios
Test the service's ability to send emails with different email providers and configurations.
Test the service's ability to fetch email data and update the SQL database.
Test the service's performance under high volume email sending and database updates.
Test the service's error handling and logging mechanisms.
Test the service's security features, such as database authentication and encrypted email communication.
Deployment and Maintenance
6.1. Deployment
The Windows service will be deployed on a server with the necessary .NET Framework and SQL Server installed.
Configure the service with the required SMTP settings and database connection strings.
6.2. Maintenance
Regularly monitor the service logs for errors and exceptions.
Update the service as needed to accommodate changes in email providers' APIs and security requirements.
Optimize the service performance periodically by monitoring resource usage and addressing any bottlenecks.
