Mongodb架构设计（一个架构与多个架构）

Question

我一直致力于使用mongodb存储数据的项目。在过去，我总是使用SQL，但我想我会尝试我们的mongodb。既然编写了代码并且站点正在运行并且正在运行，那我就开始怀疑我是否有效地设计了数据库。整个站点使用一个模式，但我想知道使用多个模式是否更清晰。

accounts[].reservations[]，accounts[].listings[].messages[]和accounts[].listings[].prices[]会变得非常大，而且我发现因为我在对象数组中有很多对象，所以＆＃39;很难设置/更新东西。我怎么能更好地解决这个问题？

这是我得到的：

var Account = new Schema({
    username: String,
    password: String,
    created: {type: Date, default:Date.now},
    accounts: [
        {
            type: {type: String, default: "Airbnb"}, // Airbnb, VRBO....
            airbnbUsername: String,
            airbnbPassword: String,
            airbnbUserID: String,
            airbnbAccessToken: String,
            lastLoginAttemptSuccessful: {type: Boolean, default: false},
            listings: [
                {
                    id: String,
                    airbnbName: String,
                    airbnbCheckInTime: Number,
                    airbnbCheckOutTime: Number,
                    airbnbListingID: String,
                    airbnbTimeZone: String,

                    pricesUpdatedLast: Date,

如果您想查看更多代码，我最近刚开源该项目。它是auto messaging and pricing engine for airbnb hosts：
