数据仓库入门（实验1）创建数据源
首先需要创建一个数据源，SSAS（分析服务）将利用数据源来连接源数据库。一、准备环境1.准备SQLServer 安装一台SQLServer2012。2.安装DEMO数据库 下载一个演示
首先需要创建一个数据源，SSAS（分析服务）将利用数据源来连接源数据库。
一、准备环境
1. 准备SQL Server
安装一台SQL Server 2012。
2. 安装DEMO数据库
下载一个演示数据库 。本实验用到的数据库为：
AdventureWorksDW2012 Data File
application, 206080K, uploaded Mar 12, 2012
3. 准备SSDT
从 SQL Server 2005 起，SQL Server将商业智能的开发功能统一到一个工具，，称为BIDS（Business Ingelligence Development Studio）。在SQL Server Denali CTP3时称为SSDT（SQL Server Developer Tools），SQL Server 2012 将其重新命名为SSDT（SQL Server Data Tools）。
这个SSDT工具实际上就是Visual Studio。安装 SQL Server 2012 时，如果本机没有事先安装 VS2010，那么 SQL Server 2012 安装程序会在本机安装一个 VS2010 的 partner 版本。
二、启动SSDT，新建项目
启动SSDT，实际上是启动了VS2010，然后利用“商业智能”模板来创建和管理一个BI解决方案。
三、创建数据源
对于数据源的概念，可以将其简单理解为类似于ODBC设置数据源的功能。
测试连接，如果正确连接到数据库，则出现以下信息：

When might a full table scan be faster than using an index in MySQL?
Apr 09, 2025 am 12:05 AM
Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.
MySQL: Simple Concepts for Easy Learning
Apr 10, 2025 am 09:29 AM
MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.
MySQL: The Ease of Data Management for Beginners
Apr 09, 2025 am 12:07 AM
MySQL is suitable for beginners because it is simple to install, powerful and easy to manage data. 1. Simple installation and configuration, suitable for a variety of operating systems. 2. Support basic operations such as creating databases and tables, inserting, querying, updating and deleting data. 3. Provide advanced functions such as JOIN operations and subqueries. 4. Performance can be improved through indexing, query optimization and table partitioning. 5. Support backup, recovery and security measures to ensure data security and consistency.
MySQL's Role: Databases in Web Applications
Apr 17, 2025 am 12:23 AM
The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.
MySQL: An Introduction to the World's Most Popular Database
Apr 12, 2025 am 12:18 AM
MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.
Explain the role of InnoDB redo logs and undo logs.
Apr 15, 2025 am 12:16 AM
InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.
MySQL's Place: Databases and Programming
Apr 13, 2025 am 12:18 AM
MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen
Why Use MySQL? Benefits and Advantages
Apr 12, 2025 am 12:17 AM
MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4.
