c# – NoSQL世界中的唯一性是什么意思,我如何处理MongoDB中的关

也许我期待MongoDb过多,或者我还没有掌握NoSQL数据库中的关系概念.

基本上,以下测试失败,我想知道如何模拟用户和组之间的这种关系(这是1：0..N关系).

[TestFixture]
public class MongoDbExamples
{

    private MongoServer _mongoServer;

    [TestFixtureSetUp]
    public void FixtureSetUp()
    {
        _mongoServer = MongoServer.Create();
    }

    [TestFixtureTearDown]
    public void FixtureTearDown()
    {
        _mongoServer.Disconnect();
    }


    [Test]
    public void RelationTest()
    {
        var database = _mongoServer.GetDatabase("StackoverflowExamples");

        var p = new Person() { Name = "Testperson" };
        var persons = database.GetCollection<Person>("Persons");
        persons.Save<Person>(p);

        var group = new Group() { Description = "A fancy descriptor" };
        group.Add(p);
        var groups = database.GetCollection<Group>("Groups");
        groups.Save<Group>(group);

        var readPerson = persons.FindOneById(p.Id);
        readPerson.Name = "a different name";
        // since the id hasn't change this is an update of the original person:
        persons.Insert<Person>(readPerson);

        // and I thought that it should be reflected in the group as well:
        var readGroup = groups.FindOneById(group.Id);
        Assert.AreEqual(readPerson.Id,readGroup.persons[0].Id); // this passes,the id is the same
        Assert.AreEqual(readPerson.Name,readGroup.persons[0].Name); // this fails,the groups person still has the old name
    }

}

这种关系有最佳实践吗？例如.是否应该搜索所有收藏/文件中的所有人并与人员收藏的匹配人交换那些人？或者是NoSQL数据库不擅长的关系,我应该避免关系(我想知道如何在更大的系统中使用NoSQL-DB然后使用更复杂的对象图)？
