甲骨文自收购SUN以来，首次发布SUN旗下MySQL产品线的最新版本―MySQL Enterprise。甲骨文表示，MySQL Enterprise最新版本即将面市，并以此显示甲骨文公司正在持续投资MySQL。
甲骨文在新闻公告中称，MySQL企业监控器2.2(MySQL Enterprise Monitor 2.2)是该版本的关键组件之一。MySQL企业监控器2.2不仅增强了对查询性能的监控，还提高了安全性，并节省了与MySQL支持集成的时间。该版本增强了收集、搜索和查看查询性能数据的功能，使开发人员能够分析和过滤可能干扰关键系统资源的模式。
MySQL是全球范围内受中小企业和互联网公司欢迎的开源数据库软件。被SUN公司收购之后，又因甲骨文收购SUN而并入到甲骨文旗下。甲骨文是全球顶级数据库软件公司，旗下Oracle数据库软件与MySQL一定程度上存在竞争关系。随着MySQL并入甲骨文，很多用户担心他们正在使用的MySQL软件得不到更新和服务。
MySQL的国内分销商在其网站称，全球目前有超过1200万个MySQL安装，每天在MySQL网站有50,000个下载，“没有其他开源数据库像MySQL这样流行”。

MySQL BLOB: how to optimize BLOBs requestsMay 13, 2025 am 12:03 AMOptimizing 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.

MySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AMBest 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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
