课程名称：Azure Cosmos DB - 针对繁忙的 .Net 开发者的 NoSQL 数据库 课程概述：现代应用程序需要具备高响应性和始终在线的特性。为了实现低延迟和高可用性，这些应用程序的实例需要部署在靠近用户的数据中心。应用程序必须能够实时响应高峰时段的使用量大幅变化，存储不断增加的数据量，并以毫秒级的速度向用户提供这些数据。Azure Cosmos DB 是一个完全托管的 NoSQL 数据库，旨在满足现代应用开发的需求。其具有单数毫秒的响应时间，以及自动即时的可扩展性，确保在任何规模下都能保持高速度。 借助 Azure Cosmos DB，应用开发的速度和生产效率得以提升，用户可以在全球范围内实现即插即用的多区域数据分发，以及支持流行语言的开源 API 和 SDK。作为一种完全托管的服务，Azure Cosmos DB 让数据库管理的负担从你身上解脱出来，自动处理管理、更新和修补工作。同时，它还以经济高效的无服务器选项和自动扩展功能来管理容量，以应对应用需求，实现供需匹配。 课程内容包括导论、非关系型数据库、横向扩展、数据建模、分区键、嵌入实体、引用实体、文档限制等基础知识，以及实践环节，涵盖创建 Cosmos DB、Cosmos DB 模拟器、连接存储资源管理器、创建容器（表）、将 SQL 数据迁移至 Cosmos DB、JSON 上传及查询等操作。最后，还将介绍如何在 .Net Web API 中进行编码，包括在容器中插入项、更新项、检索所有项、以及使用过滤器检索项等内容。
Today's applications are required to be highly responsive and always online. To achieve low latency and high availability, instances of these applications need to be deployed in data centers that are close to their users. Applications need to respond in real-time to large changes in usage at peak hours, store ever-increasing volumes of data and make this data available to users in milliseconds.Azure Cosmos DB is a fully managed NoSQL database for modern app development. Single-digit millisecond response times, and automatic and instant scalability, guarantee the speed at any scale.App development is faster and more productive thanks to turnkey multi-region data distribution anywhere in the world, open-source APIs, and SDKs for popular languages. As a fully managed service, Azure Cosmos DB takes database administration off your hands with automatic management, updates, and patching. It also handles capacity management with cost-effective serverless and automatic scaling options that respond to application needs to match capacity with demand.So let's start rolling: Introduction - Non Relational,Horizontal Scaling,Data Modeling,Partition Key,Embedding Entities,Referencing Entities,Document Limit,Data ModelingHands-On - Create Cosmos DB, Cosmos DB Emulator, Attaching to Storage Explorer, Create Container (Table), Migrate SQL Data to Cosmos DB, Json Uploads, QueryingCoding.Net Web API - Insert Item in Container, Update Item, Retrieve All Items, Retrieve Items with filters
