### 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.

Vamos criar uma **dependência** do FastAPI com `yield` que fornecerá uma nova `Session` para cada requisição. Isso é o que garante que usamos uma única sessão por requisição. 🤓

import org.apache.maven.execution.MavenExecutionRequest;

/**
 * Strictly internal component able to "extend" {@link MavenExecutionRequest} in some way before it is used to
 * construct resolver session.
 *
 * @since 4.0.0
 */
interface MavenExecutionRequestExtender {
    void extend(MavenExecutionRequest mavenExecutionRequest);

 *
 * @since 3.0-alpha
 */
public interface GraphBuilder {
    String HINT = "graphBuilder";

    Result<? extends ProjectDependencyGraph> build(MavenSession session);

            user.put("session.rootDirectory", invokerRequest.rootDirectory().toString());
            user.put("session.topDirectory", invokerRequest.topDirectory().toString());
            Map<String, String> system = new HashMap<>(invokerRequest.systemProperties());
            this.session = ProtoSession.create(user, system);
        }

        public Logger logger;

### Create the Tables

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

### Create a Session Dependency

            try ( SmbTreeHandleInternal treeHandle = (SmbTreeHandleInternal) f.getTreeHandle();
                  SmbSessionInternal session = treeHandle.getSession().unwrap(SmbSessionInternal.class) ) {
                assertNotNull(session);
                try ( SmbTransportInternal transport = session.getTransport().unwrap(SmbTransportInternal.class) ) {
                    assertNotNull(transport);
