Building Resilient Embedded Apps: Working with Data and Constraint Management in SQLite

In the world of modern software, not every application needs a massive, server-based database cluster. Sometimes, the most powerful tool is the one that lives right inside your application. SQLite is the unsung hero of the tech world, powering everything from mobile apps to web browsers. If you are ready to move beyond simple spreadsheets and start building professional-grade local storage solutions, this journey through the SQLite learning path is your perfect starting point.
