现在越来越的数据库厂商,例如:SAP、Oracle正在向商业智能发展,通过对现有的数据分析、挖掘以预测未来市场发展曲线。“SQL Server 2008已经摆脱只是数据库工具形象,而要成为新一代智能的数据平台”微软(中国)服务器产品业务群总监符国新表示。
10月,SQL Server2008简体中文版将在中国正式上市,是至今为止最强大和最全面的SQLServer版本,相较于此前版本,SQLServer2008增加了很多新功能,例如:可以对整个数据库、数据文件和日志文件进行加密,而不需要改动应用程序;为了在线添加内存资源而扩展SQLServer中的已有的支持,热添加CPU使数据库可以按需扩展。事实上,CPU资源可以添加到SQLServer2008所在的硬件平台上而不需要停止应用程序。
SQL Server2008CTP(共享技术预览)版推出至今,已经有全球超过45万客户和合作伙伴对其下载,开发超过75项大型应用,并由近1000家ISV开发出超过1350项应用程序。在中国,包括广州建委、厦门银行、四川移动以及天狮集团都已经部署了SQLServer2008。
谈及SQL Server 之前版本升级到SQL Server2008的过程,微软(中国)服务器产品业务群SQLServer产品市场经理郝雪莹介绍说这一过程非常简单:“微软所有的管理基本都会提供图形化的界面,用户可以根据分析报告,按照指示就可以升级了。如果用户以前用的是其它厂商的产品,微软会提供"迁移帮助"工具,同样出一个报告,对历史的数据库做一个评估,指示用户逐步完成迁移,帮助用户将旧有系统升级以最优化的方式平滑升级到SQLServer2008中。”
SQLServer是微软应用平台中一个关键组成部分,在发布企业版的同时,还将提供适用于中小型应用规模的标准版、工作组版、以及180天试用的评估版及免费的学习版。

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.
