## Criar o App com um Único Modelo

Vamos criar a primeira versão mais simples do app com um único modelo **SQLModel**.

Depois, vamos melhorá-lo aumentando a segurança e versatilidade com **múltiplos modelos** abaixo. 🤓

### Criar Modelos

Importe o `SQLModel` e crie um modelo de banco de dados:

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[1:11] hl[7:11] *}

            }
        };

        // Execute stop
        dataStore.stop();

        assertTrue(stopCalled.get());
    }

    public void test_stop_multipleCalls() {
        // Test multiple stop calls
        final AtomicInteger stopCallCount = new AtomicInteger(0);

        dataStore = new DataStore() {
            @Override

    @Test
    public void testConvertWithMultipleLanguages() throws IOException {
        // Test convert with multiple languages
        String text = "test text";
        String field = "content";

        List<String> results = converter.convert(text, field, "en", "ja");

        assertNotNull(results);
        // With multiple languages, should use ReadingConverterChain
    }

    @Test

        user = new TestFessUser("ユーザー名", new String[] {}, new String[] {}, new String[] {});
        assertEquals("ユーザー名", user.getName());
    }

    public void test_getRoleNames() {
        // Test with multiple roles
        String[] roles = { "admin", "user", "manager" };
        FessUser user = new TestFessUser("testuser", roles, new String[] {}, new String[] {});
        assertArrayEquals(roles, user.getRoleNames());

	"sync"
