Designing 1 applications doesn't seem to be difficult, but it's not easy to achieve the optimal performance of the system. There are many choices in development tools, database design, application structure, query design, interface selection, and so on, depending on the specific application requirements and the skills of the development team. This article takes SQL Server as an example, discusses the application performance optimization techniques from the perspective of the background database, and gives some useful suggestions. 1 database design to achieve optimal performance in a good SQL Server scenario, the key is to have 1 ...

In 2017, the double eleven refreshed the record again. The transaction created a peak of 325,000 pens/second and a peak payment of 256,000 pens/second.

Last week, we described how to evaluate the code used to extend cloud applications. Now, we're going to look at the coding and system-change strategies that are likely to make the system more vulnerable over time. Because of the seemingly never-ending development requirements of the CRM system, the durability of our code will be a key factor in the long-term smooth running of these systems. But before I begin, I need to declare that the usages and terms I cite apply only to the salesforce.com environment, and that other applications and platforms use different types of association ...
