JSON数据库基础** **1.1 JSON数据模型与特性** JSON(JavaScript Object Notation)是一种轻量级的数据交换格式,基于JavaScript对象语法。它使用键值对的形式存储数据,键为字符串,值可以是各种类型,如字符串、数字、布尔值、数组或嵌套对象。JSON的灵活性和可扩展性使其成为存储和传输复杂数据的理想选择。 **1.2 MongoDB和CouchDB等JSON数据库简介** MongoDB和CouchDB是流行的JSON数据库,它们将JSON数据存储在文档中。文档是键值对的集合,其中键是字段名称,值是字段值。MongoDB使用BSON(二进制JSON)格式存储文档,而CouchDB使用JSON格式存储文档。这些数据库提供了丰富的查询和索引功能,使开发人员能够高效地处理和检索JSON数据。 # 2. 电商网站数据建模 ### 2.1 产品数据建模 #### 2.1.1 产品基本信息 产品基本信息是电商网站中最重要的数据类型之一,它描述了产品的核心属性,例如: - 产品ID - 产品名称 - 产品描述 - 产品价格 - 产品库存 这些属性可以存储在一个JSON文档中,如下所示: ```json { "productId": "12345", "productName": "iPhone 13 Pro Max", "productDescription": "6.7英寸Super Retina XDR显示屏,A15仿生芯片,1200万像素三摄系统", "productPrice": 999, "productStock": 100 } ``` #### 2.1.2 产品分类和属性 为了便于产品管理和搜索,需要对产品进行分类和添加属性。分类可以是多级的,例如: - 电子产品 - 智能手机 - 苹果手机 - iPhone 13 Pro Max 属性可以描述产品的具体特性,例如: - 颜色 - 存储容量 - 操作系统 这些分类和属性可以存储在单独的JSON文档中,并通过引用与产品基本信息关联,如下所示: ```json { "categoryId": "1", "categoryName": "电子产品" } { "attributeId": "1", "attributeName": "颜色", "attributeValues": ["黑色", "白色", "蓝色"] } { "productId": "12345", "categoryId": "1", "attributes": [ { "attributeId": "1", "attributeValue": "黑色" }, { "attributeId": "2", "attributeValue": "512GB" }, { "attributeId": "3", "attributeValue": "iOS 15" } ] } ``` ### 2.2 订单数据建模 #### 2.2.1 订单基本信息 订单基本信息记录了订单的概要信息,包括: - 订单ID - 订单日期 - 订单状态 - 订单金额 - 用户ID 这些信息可以存储在一个JSON文档中,如下所示: ```json { "orderId": "67890", "orderDate": "2023-03-08", "orderStatus": "已完成", "orderAmount": 1234.56, "userId": "123" } ``` #### 2.2.2 订单商品明细 订单商品明细记录了订单中包含的商品信息,包括: - 商品ID - 商品数量 - 商品单价 - 商品总价 这些信息可以存储在一个JSON数组中,如下所示: ```json [ { "productId": "12345", "quantity": 1, "unitPrice": 999, "totalPrice": 999 }, { "productId": "56789", "quantity": 2, "unitPrice": 499, "totalPrice": 998 } ] ``` ### 2.3 用户数据建模 #### 2.3.1 用户基本信息 用户基本信息描述了用户的个人资料,包括: - 用户ID - 用户名 - 密码 - 邮箱地址 - 手机号码 这些信息可以存储在一个JSON文档中,如下所示: ```json { "userId": "123", "username": "john", "password": "123456", "email": "john@example.com", "phoneNumber": "1234567890" } ``` #### 2.3.2 用户行为数据 用户行为数据记录了用户的操作和浏览历史,包括: - 用户ID - 操作类型 - 操作时间 - 操作对象 这些信息可以存储在一个JSON数组中,如下所示: ```json [ { "userId": "123", "operationType": "浏览产品", ```
