据Net Applications统计,2013年2月浏览器市场份额,IE高歌猛进,持续增长,占市场份额为55.8%。其中排名第二和第三的是Firefox和Chrome,分别占据了20.12%和16.27%。而Chrome这个成绩也是创下了17个月来的新低。
与1月份相比,IE同比增长了0.68%,其中,IE9是一月份增长速度最快的IE浏览器版本,增长了0.74%,占市场份额为21.67%;而Fierfox比上月增长0.18%;而Chrome则继续跌落,下降了1.56%。此外值得一提的是,Safari上涨了0.18%,占5.42%,而Opera持续增长,由1.75个百分点增长至1.82个百分点。
IE浏览器全球市场份额从今年1月首次突破55%大关至55.14%,而2月份在此基础上更进一步,达到55.82%。
IE10在2月份的市场份额仅比1月份增长了0.29%,为1.58%;这似乎也说明IE10的推广之路并没有那么一帆风顺,但在上月的27号, 微软正式发布了Win7版的IE10,这是否会推动IE10的市场占有率呢?而IE9则增长了0.74%,占市场份额为21.67%,是本月IE浏览器中增长速度最快且很有可能会在此后成为最受用户欢迎的浏览器;而IE 8份额下滑0.16%,但仍是用户首选IE浏览器版本,所占市场份额为23.38%。IE7和IE6则分别在2月份下滑了0.12%和0.36%。IE10很有可能会后来居上,赶超IE7和IE6。
Firefox浏览器仍在20%附近徘徊,其中Firefox 19在发布不到一个月的时间里占据了3.32%;而Firefox 18增长了2.77 %,占市场份额为11.05%,而其他所有旧版本Firefox份额均出现下滑,Firefox 17和Firefox 16分别下滑了5%和0.26%。
Chrome在2月份仅占了16.27%,这似乎也说明Chrome赶超Firefox的希望越来越渺茫。其中Chrome 25份额增长了3.14%, Chrome 24增长2.18%,所占份额为10.88%;
Chrome 23下滑6.13%,而Chrome 22下滑0.2%。
以上数据都是由Net Applications公司发布,每月数据由1.6亿的独立访问用户构成,并且该公司还为其客户监测4万个网站。

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA
