The document discusses how to use SQLite databases in a Universal Windows Platform (UWP) application. It includes instructions to install SQLite extensions from NuGet and create, read, update and delete database records using CRUD operations. It provides code examples to create a database, insert, retrieve, update and delete student records from the database and bind the data to a list view.

- 2. Install SQLite-UAP extensions form NuGet Package Manager
- 3. Next Install SQLite.Net-PCL extension from NuGet Package
- 4. • Include 4 functions CRUD Operations • Bind data to a ListBox
