SQL Server应用模式之OLTP系统性能分析

OLTP系统的最大特点，是这类应用里有大量的，并发程度比较高的小事务，包括SELECT、INSERT、UPDATE和DELETE。 这些操作都比较简单，服务器空间，事务时间也不会很长，但是要求的返回时间很严格，基本上需要在几秒钟内必须返回。
支持生产流水线的数据库应用，美国服务器，是很典型的OLTP系统。一件产品从原材料到组装成最后的产品，中间会有很多道工序。每道工序本身不复杂，不会花很多时间。工厂需要使用数据库应用记录和监督每一道工序。在流水线上，工人可以扫描产品上的条形码，快速的输入产品加工、处理或检验结果。这些输入和修改过程都会很简单，而且很多在数据库里会是INSERT、UPDATE或DELETE动作。但是应用的响应速度要求非常高，最后等待的时间可以忽略不计。如果工人输入一个条形码以后要等几秒钟，很多他在处理每一件产品的时候，都会多花几秒钟。如果他要花几十秒，那么整个流水线的运转就会很慢。如果系统出了问题，他每处理一个产品都要花几分钟，那么流水线就会瘫痪，工人们都可以去喝茶了。数据库管理员这时将面对的是心急如焚的管理高层。
所以OLTP系统在设计的时候，香港虚拟主机，要非常小心，像那种由于一条语句而导致整个服务器范围的阻塞，是绝对要避免的。
OLTP系统要注意避免出现的问题主要提现在以下几个方面。

May 03, 2024 pm 09:03 PM
The performance comparison of PHP array key value flipping methods shows that the array_flip() function performs better than the for loop in large arrays (more than 1 million elements) and takes less time. The for loop method of manually flipping key values takes a relatively long time.
Huawei will launch the Xuanji sensing system in the field of smart wearables, which can assess the user's emotional state based on heart rate
Aug 29, 2024 pm 03:30 PM
Recently, Huawei announced that it will launch a new smart wearable product equipped with Xuanji sensing system in September, which is expected to be Huawei's latest smart watch. This new product will integrate advanced emotional health monitoring functions. The Xuanji Perception System provides users with a comprehensive health assessment with its six characteristics - accuracy, comprehensiveness, speed, flexibility, openness and scalability. The system uses a super-sensing module and optimizes the multi-channel optical path architecture technology, which greatly improves the monitoring accuracy of basic indicators such as heart rate, blood oxygen and respiration rate. In addition, the Xuanji Sensing System has also expanded the research on emotional states based on heart rate data. It is not limited to physiological indicators, but can also evaluate the user's emotional state and stress level. It supports the monitoring of more than 60 sports health indicators, covering cardiovascular, respiratory, neurological, endocrine,
How to optimize the performance of multi-threaded programs in C++?
Jun 05, 2024 pm 02:04 PM
Effective techniques for optimizing C++ multi-threaded performance include limiting the number of threads to avoid resource contention. Use lightweight mutex locks to reduce contention. Optimize the scope of the lock and minimize the waiting time. Use lock-free data structures to improve concurrency. Avoid busy waiting and notify threads of resource availability through events.
