functions in JS, and the direct amount of functions is one of them. like var fun = function () {}, where function does not assign a value to fun then it is an anonymous function.OK, let's see how anonymous functions are called.1. function call to get return value after executionMethod One, call the function and get the return value. Forcing an operator to make a function call Execute(function (x, y) {alert (x+y);return x+y;} (3,4));Method Two, call the function, get the return value. Forces the

tight coupling to loose coupling, so that most analytical applications do not cause any changes in the data layer, whereas the MPP-based business intelligence system is able to perform high-performance analysis of detail data directly. This allows users to quickly develop data applications and then perform real-time analysis. 3Concluding remarksDT the arrival of the times, the value of data will be more and more people find, especially for large groups of enterprises, data from the production,

Time management is a necessary skill for managers, through the use of tomatoes, this goal, mailbox, our time management capacity is also constantly strengthening. Time management so that we can
fast ... In our test of using business data, the serialization/deserialization performance of PROTOBUF is about three times times that of Json.NET, and the serialized volume is about One-second of JSON, which can improve the throughput performance of WEBAPI to a considerable degree.Disadvantages of ProtobufThe DTO layer must refer to Protobuf-net to add attributes, which in some way leads to code intrusion. Basically dtos belong to Poco, relying on third-party package of words always feel a bit

The calculation formula of purchase quantity of single goods is generally:
The best purchase quantity = Low limit ≤ (planned dosage + inventory low limit – on-hand inventory) ≤ inventory High-limit
which
Inventory low limit must be guaranteed, inventory high-limit in the procurement for reference only.
On-hand inventory = existing physical stock + in-transit inventory
Existing physical stock = Posted Invent
Business scenario:

Print until the end of 75.There are two points to the main question:The 1th is that no other threads appear during the process of printing the threadThe 2nd is that the process of thread entry is orderly, as above 123123.
