### Criar as Tabelas

Em seguida, adicionamos uma função que usa `SQLModel.metadata.create_all(engine)` para **criar as tabelas** para todos os *modelos de tabela*.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[21:22] hl[21:22] *}

### Criar uma Dependência de Sessão

Uma **`Session`** é o que armazena os **objetos na memória** e acompanha as alterações necessárias nos dados, para então **usar o `engine`** para se comunicar com o banco de dados.

				{header: xlMetaV2VersionHeader{
					VersionID: [16]byte{1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1},
					ModTime:   baseTime.Add(15 * time.Minute).UnixNano(),
					Signature: [4]byte{2, 1, 1, 1},
					Type:      ObjectType,
					Flags:     0,
				}},
			},
		},
		// Has another version prior to the one we want.
		2: {
			versions: []xlMetaV2ShallowVersion{

### Create the Tables

We then add a function that uses `SQLModel.metadata.create_all(engine)` to **create the tables** for all the *table models*.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[21:22] hl[21:22] *}

### Create a Session Dependency

A **`Session`** is what stores the **objects in memory** and keeps track of any changes needed in the data, then it **uses the `engine`** to communicate with the database.
