+This article demonstrates how to install SQLx with the SQLite feature and use it with Tauri, focusing on the Rust side.
+
+## Install SQLx
+
+To install SQLx with the Tokio runtime and SQLite support, add the following to the `[dependencies]` section of your `src-tauri/Cargo.toml` file:
+
+```toml
+[dependencies]
+# SQLx with Tokio (no TLS) and SQLite support
+sqlx = { version = "0.8", features = [ "runtime-tokio", "sqlite"] }
+```
+
+## Connect to the Database
+
+Create an asynchronous method to establish a connection to the SQLite database and return a connection pool:
+
+```rs
+async fn establish_connection() -> SqlitePool {
+    SqlitePoolOptions::new()
+        .max_connections(5)
+        .connect("sqlite://")
+        .await
+        .expect("Unable to connect to SQLite database")
+}
+```
+
+## Store the Connection Pool
+
+Create a struct to store the database connection pool:
+
+```rs
+struct AppData {
+    db_pool: SqlitePool,
+}
+```
+
+Next, initialize the connection pool:
+
+```rs
+// Create a connection pool
+let db_pool: SqlitePool = block_on(establish_connection());
+```
+
+Store the connection pool in the application state:
+
+```rs
+ app.manage(AppData { db_pool });
+```
+
+## Access the Database in an Async Command
+
+To interact with the database from an asynchronous command, define a Tauri command like this:
+
+```rs
+#[tauri::command]
+async fn db_test(state: State<'_, AppData>) -> Result<(), String> {
+    // You can now interact with the database using `state.db_pool`
+    Ok(())
+}
+```
