开篇有益:为什么选择MongoDB?
为啥用MongoDB？
赶NoSQL时髦?
Auto-shard等激动人心的特性?
•No! 08年，还都是浮云。
最初的想法是寻找一个可靠的分布式K/V解决MySQL的问题。
NoSQL(NoSQL = Not Only SQL )，意即反SQL运动，是一项全新的数据库革命性运动，早期就有人提出，发展至2009年趋势越发高涨。NoSQL的拥护者们提倡运用非关系型的数据存储，相对于目前铺天盖地的关系型数据库运用，这一概念无疑是一种全新的思维的注入。
所以说，NoSQL不仅仅是产品，更是一项运动!

继续使用Memcached？
决定：寻找Memcached替代品
选中Flare：
证
项目开发1个月后：
（1）个人能力有限，无法解决一些灵异事件
（2）没有开发者社区
（3）不懂日文
新的候选者MongoDB：
胆子大一点MySQL ＋MongoDB?
可实现
据，代码逻辑有些复杂
能否彻底抛弃MySQL?
胆子再更大一点好吧，试试：
MongoDB,就是它了一举两得的加分项：GridFS
力
综上原因，选对了!
有问必答
碑良好
本文参收集网络资料整理，作为我选择MongoDB的一个参考。

Is the conversion speed fast when converting XML to PDF on mobile phone?
Apr 02, 2025 pm 10:09 PM
The speed of mobile XML to PDF depends on the following factors: the complexity of XML structure. Mobile hardware configuration conversion method (library, algorithm) code quality optimization methods (select efficient libraries, optimize algorithms, cache data, and utilize multi-threading). Overall, there is no absolute answer and it needs to be optimized according to the specific situation.

Does XML modification require programming?
Apr 02, 2025 pm 06:51 PM
Modifying XML content requires programming, because it requires accurate finding of the target nodes to add, delete, modify and check. The programming language has corresponding libraries to process XML and provides APIs to perform safe, efficient and controllable operations like operating databases.
What is the priority of C language !x?
Apr 03, 2025 pm 02:06 PM
The logical non-operator (!) has the priority next to parentheses, which means that in expressions, it will precede most other operators. Understanding priority not only requires rote memorization, but more importantly, understanding the logic and potential pitfalls behind it to avoid undetectable errors in complex expressions. Adding brackets can clarify expression intent, improve code clarity and maintainability, and prevent unexpected behavior.

Best practices for C language default
Apr 03, 2025 pm 03:48 PM
The best practices of default in C language: place it at the end of the switch statement as the default processing for unmatched values; it is used to handle unknown or invalid values to improve program robustness; avoid duplication with case branches to maintain conciseness; comment clearly on the purpose of the default branch to improve readability; avoid using multiple defaults in one case to maintain clarity; keep the default branch concise and avoid complex operations; consider using enumeration values as case conditions to improve maintainability; in large switch statements, use multiple default branches to handle different situations.
