-projects, multiple projects can be reused. initially, only to do the basic common functions, the latter can be completed separately to improve the accounting system. implementation idea: WebService, the internal call introduces the jar package, just like calling a normal API. problem: Webserbice provides a service interface that can be accessed directly via HTTP. I feel that the internal system uses webservice, the code will be very clear. But to others, others will not necessarily use Java, us

A set of ERP system will have CRM, it is impossible to say that all my data are scattered, you want to use just write one. You go out and talk to people, you must say I have something here, and then you can tell people you do is invoicing. Ask the CRM or the financial system you say it's not my responsibility. If you've ever been in touch with a similar system, you can say that I've also done CRM, so to speak. We connect directly to the existing financial system, and you just push it out and you

Hrtimer timer WheelFirst, let's talk about timer wheel. It is the jiffies-based timer mechanism used by kernel. The interfaces include init_timer (), mod_timer (), del_timer (), etc.The emergence of hrtimer does not discard the old timer wheel mechanism (or it is unlikely to discard it :)). hrtimer is used as the timer in the kernel, while timer wheel

Windows 10 subsystems are not non-UbuntuGuideUbuntu manufacturer Canonical has long been cooperating with Microsoft and has given us a very controversial Bash on Windows experience. The outside world is also mixed. Many heavy Linux users are questioning whether it is useful, and further think that Bash on Windows is a security risk. Unix Bash is transplanted to Windows through the WSL (Windows Linux subsystem) feature. We have previously demonstrated

Label:SQL Server Agent is the core of all real-time databases. Proxies have a lot of non-obvious uses, so the knowledge of the system is useful for developers or DBAs. This series of articles will be popular to introduce its many uses. A SQL Server Agent job has a series of one or more job steps. A job step is assigned to a specific job subsystem to identify the kind of job step that will be performed. Each job step runs in its own security context, although each job has an owner who can

The main subsystems of Linux are CPU, Memory, IO, Network. in these subsystems, they are highly dependent on each other. A high load on any subsystem can cause problems in other subsystems. For example: a large number of paging requests to memory caused by the high throughput of the blocking NIC causes CPU overhead CPU overhead resulting in memory request queue a
