InquirySpark - Technical Summary InquirySpark is a .NET 10-based survey and inquiry management system that combines a modern MVC admin interface with a read-only SQLite persistence layer, designed to eliminate SQL Server dependencies while maintaining enterprise-grade data integrity. The solution comprises four interconnected projects: an ASP.NET Core admin portal styled with Bootstrap 5 and DataTables, an Entity Framework Core 10 repository layer providing abstraction over immutable SQLite databases, shared domain models and SDK objects, and a comprehensive MSTest unit test suite—all enforced through nullable reference types, XML documentation standards, and automatic npm asset pipelines. Key architectural innovations include a SqliteOptionsConfigurator pattern for centralized connection management with read-only mode enforcement, primary constructor usage for dependency injection, and an immutable database strategy that prevents schema mutations while supporting simultaneous application instances. The technology stack spans C# (39.9%), HTML/Bootstrap UI (33.5%), T-SQL schema definitions (21.7%), PowerShell automation (3.7%), and JavaScript asset management (1.2%), with no external CDN dependencies and all front-end libraries bundled locally via npm. The project targets teams seeking lightweight, self-contained inquiry systems that prioritize data immutability, simplified deployment (no database server required), and compliance-friendly audit trails through read-only data access patterns. Despite minimal recent activity (zero commits in 90 days), the codebase demonstrates mature architectural decisions and comprehensive documentation, positioning it as a viable template for organizations migrating from traditional SQL Server-based survey platforms to containerizable, cloud-native alternatives.
